在網際網路蓬勃發展的時代，電腦病毒也更加的猖獗。雖說防毒軟體百家爭鳴，但對於未知病毒的防治技術仍然束手無策。本研究的目的在追溯出電腦惡意程式運行模式，利用IDA靜態反編譯軟體與病毒原始碼尋找出病毒共同的特徵，阻斷其滋生途徑。 本研究在實驗中，研究者利用Borland C++ Builder 6作為應用程式開發環境，配合WinAPI函數與TRegistry類別設計出參數監控系統。研究顯示不論是修改於Window 9x架構下的win.ini, system.ini，或是Run與Run Service之下的資料項，本系統都能有效運作。此系統能成功的攔截到惡意程式對Registry鍵值的讀寫，亦即當使用者否決其修改鍵值時，惡意程式無法在重新開機後運行；易言之，惡意程式失去執行效力。 實驗結果發現，參數監控系統可攔截惡意程式之修改命令，防止未知病毒與惡意程式開機自動運行，以此達到未知病毒的攔截基礎技術。本研究之結果可補強市售防毒系統，對於未知病毒的攔截，能達到完整的防護效果。 Computer viruses become more rampant in the rapidly-developing era of Internet. With the various kinds of Anti-Virus software, people still can do nothing about detecting the unknown viruses. This research aims to trace back the computer virus function mode. By using IDA Pro Disassembler and Virus Source, we can find out the common characteristics of viruses. Thus, we can stop viruses from thriving. The experiment uses Borland C++ Builder 6 as the Registry Detection System by coordinating Win API and TRegistry. It works no matter by modifying win.ini and system.ini under the structure of Window 9x or by modifying Run Value and RunService Value. Moreover, it can intercept the viruses from reading and writing of the ValueKey. As the users deny the modified ValueKey, the viruses cannot run after resetting. In other words, the viruses lose their effects. The results present that Registry Detection System can intercept the modifying commands and prevent the automatic running from unknown viruses. By doing so, we can acquire the basic technology of intercepting the unknown viruses. The application of this study can improve the functions of Anti-Virus. In this way, through protection from unknown viruses can be obtained.

Purpose Although Body Mass Index (BMI) is accepted by the World Health Organisation (WHO) as the standard method of measuring a person’s obesity or lack thereof, it is restriction to the two measurements of height and weight. This makes its accuracy questionable. By using other easily obtainable body measurements, a better way of evaluating Body Mass Index is possible. The purpose of this project was to show that the BMI formula is only accurate to a certain degree and that its validity varies depending on certain factors used in my project. Procedure 50 Adolescent female aged 16-20 and 50 women aged 40-56 none of whom were noticeably obese or underweight volunteered. Using a simple questionnaire, several measurements were taken – age in months, caliper measurement of tricep and hip bone, shoe size, height in metres, hip waist and wrist measurements (cm), exercise per week, heart rate and body type. Results were tabulated and graphs drawn using EXCEL. BAI (Body Adiposity Index) measurements were calculated for all volunteers. Results The girls and women with pear and hourglass figures were classified by BMI as overweight or obese. The girls and women who exercised a lot were also unfairly classified by their BMI readings. Many of the graphs show that BMI is not accurate, however, others show that there is merit to the formula. Conclusions The results while interesting require a larger sample group to be conclusive. It would appear that the BMI formula needs to be extended in order to improve its accuracy. Further research includes: 1. Larger sample group, 2. Representative age groups, 3. Investigate males, 4. Look at data for different ethnic groups, 5. Research into BAI formula as a possible substitute, 6. Develop an improvement on BMI. Although, there is some merit to BMI formula, it could be greatly improved with the use of other measurements including those used in this project.

特定基因的表現與不同氧自由基的產生，已知會影響細胞的生長和死亡。我\r 個人有興趣利用間質幹細胞體外培養擴充，以為筋骨組織再生的可能應用。因此\r 利用轉植(transfect)突變ras 基因(Glu61Leu)進入骨髓間質細胞株(HS-5 cells)，來\r 控制ras 基因表現的高低，進而研究這些間質細胞隨著Ras 蛋白質表現的高低，\r 對氧自由基引導細胞生長與死亡之影響。結果發現ras 基因高度表現的間質細胞\r 生長減緩；相較於原生株平均減少62.4%。進一步研究其生長減少是否與細胞凋\r 亡有關，發現ras 基因高度表現的間質細胞凋亡確實比原生株高22.6%。探究其\r 凋亡原因，發現與caspase-3 有關但和粒腺體功能無關：因為caspase-3 有活化，\r 但是以粒腺體膜電位螢光追蹤劑JC-1 測得的膜電位卻沒有改變。追蹤ras 基因高\r 度表現的間質細胞其細胞內氧自由基的產量，發現Ras 高度表現株其細胞內氧自\r 由基明顯增加。當細胞外加入超氧根轉化酵素(SOD, 500 U/ml)去清除超氧根時，\r 對Ras 高度表現細胞的凋亡沒有影響；但是外加觸化酵素(catalase, 500u/ml)於培\r 養液中，卻可以抑制ras 基因高度表現的間質細胞內caspase-3 活化和細胞凋亡；\r 並且增加細胞生長循環促進分子Cyclin D1 的表現。從這些研究我們歸結出兩點\r 重要新發現: 1) ras 基因突變造成Ras 高度表現時，會促成細胞內特定氧自由基產\r 生，使得細胞生長減緩並進行細胞凋亡，只有特定抗氧化酵素(catalase)才能恢復\r 其異常； 2) Ras 蛋白高度表現而引導氧自由基產生的細胞凋亡與caspase-3 活化\r 有關，但與粒腺體功能無關。根據這些發現，未來我們或許可以朝調節特定氧化\r 還原反應或使用caspase-3 抑制劑去調控間質幹細胞的生長，以供筋骨組織再生\r 的應用。Certain gene’s expression as well as different species of oxygen radicals can\r affect cell growth and apoptosis. We are interested in amplifying mesenchymal\r progenitor cells for the application of musculoskeletal tissue regeneration. Thus, we\r transfected a mutant ras gene (61Glu/Leu) to change Ras protein expression in the\r mesenchymal progenitor cell line (HS-5 cells) and studied how ras expressing levels\r influenced intracellular oxygen radicals, and its relationship to cell growth and\r apoptosis. Results showed that Ras over-expressing HS-5 cells grew slower than those\r with wild type ras HS-5 cells and revealed a higher apoptosis rate. The higher\r apoptosis in Ras over-expressing cells was not related to mitochondrial dysfunction\r since mitochondrial membrane potential was normal as determined by flow\r cytometric analysis of JC-1 fluorescent staining assay. The higher apoptosis was\r related to higher caspase-3 activation. Further studies showed that Ras\r over-expressing HS-5 cells revealed a higher production of intracellular oxygen\r radicals in comparison to those with wild type ras HS-5 cells. Addition of catalase\r (500 u/ml) but not superoxide dismutase (SOD; 500 u/ml) specifically revived the cell\r growth associated with increase of cyclin D1 expression, but decrease of apoptosis\r associated with lower caspase-3 activation. Results from these studies demonstrated\r two important findings: 1) the ras gene over-expressing in a ras-mutant HS-5 cell line\r triggers a higher production of intracellular oxygen radicals resulting in higher cell\r apoptosis; and 2) the higher oxygen radicals related cell apoptosis is mediated by\r caspase-3 but not mitochondrial dysfunction. Based on these findings, we may\r propose to regulate mesenchymal progenitor cell growth for musculoskeletal tissue\r regeneration via modulation of redox reactions or caspase-3 inhibitors in the future.

It is hoped that this research will provide a foundation to further promulgate the high school science education and research, and may enrich the natural ecology protection and education materials for the loving care of local environment. The investigation started from April, 2003 to May, 2004, or for 14 months period and amounted to 85 times of field observations at night. It was confirmed that there were 37 species of amphibious and reptile ( 2 classes 3 aria 13 families 24genus),amphibious species: 4 families 13 species, lizard: 4 families 9 species, snake: 4 families 13 species, turtle: 1 family 2 species. In regard to the number of times of appearances, amphibious species of Rana latouchii had the most appearances with 1,547 times, and the least appearances was the Rana longicrus and the Rana swinhoana with only 6 times; for the lizards, Japalura polygonata xanthostoma had the most appearances with 1,995 times, and the least appearances was Eumeces elegans with only 4 times; for the snake and turtle, Trimeresurus mucrosquamatus had the most appearances with 85 times; for the Amphiesma sauteri sauteri, Boiga kraepelini, Lycodon ruhstrati ruhstrati, Oligodon formosanus, Ptyas mucosus, Ramphotyphlops braminus , Cistoclemmys flavomarginatn and Mauremys mutica , each had appeared only 1 time. On the appearance frequency, within the 14 months, amphibious species Rana latouchii and Rana kuhlii, Rana latouchii appreared 97.65%, the highest within the 85 investigations period, and the least was the Rana longicrus with only 3.53%; lizard Japalura polygonata xanthostoma had appeared within these 14 months, but in 85 investigations period, their frequency was 75 times, or 97.65% at the highest frequency. Eumeces elegans there upon within the 14 months and 85 investigations, had the lowest frequency each at 21.43% and 3.53%; for the snake and the turtle species, Trimeresurus mucrosquamatus within the 14 months and 61 appearances had the highest frequency record at 100% and 71.76%; but Cistoclemmys flavomarginata and Mauremys mutica only appeared once in a month and, therefore its frequency was at 7.14% and 1.18%. For the distribution breadth, in 22 investigation sample areas, amphibious species take Rana latouchii of the amphibious kind had the biggest record at 95.45%, and the smallest was Rana longicrus and Rana swinhoana at 18.18%; for the lizards, Japalura polygonata xanthostoma was 100% as the biggest, and the smallest was Hemidactylus bowringii at 9.09%; for the snake, the Trimeresurus mucrosquamatus was at 86.36% as the biggest; the turtle species had only 4.55% distribution breadths. For the number of appearance in each area, amphibious species in area A had the most with 11 species, lizard of second period school area had the most with 7 species, the snake of area AB had the most with 9 species. In all other areas, the amphibious reptile species number in area AB had the most with 22 kind of species. From the results of the research, the biodiversity of amphibious and reptile species within the investigation areas is very high, Rana latouchi is the codominant of Frog; Japalura polygonata xanthostoma is the codominant of Lizard, and Trimeresurus mucrosquamatus is the codominant of Snake.

In our daily life, objects and the contacts between objects they will have mutually affect each other, some initially chaotic systems after a sufficient amount of time will mutually correct each other, and finally achieve synchronization (example: the speed of bird and fish migration, market prices, infantry…), although some are unable to achieve this. We will illustrate and explain the synchronization system, its process and discover the conditions for synchronization. Using linking concepts, we will integrate the coupled map lattices with global coupling and coupled map lattices with intermediate-range models into a synchronization mode in order to simulate a synchronization system. We first used a small system of n≦50 to obtain results that will demonstrate the linking concepts: 1. The more chaotic a system, a longer period of time is required for synchronization. 2. An increase in the number of individual objects requires an increase in the range of concepts and the amount of time in order to achieve an in depth synchronization. 3. Initial concept values which randomly effect synchronization critical point conditions are not obvious in a mathematically incorrect graph. In a closer look, when we increased the synchronization to n≦400 and the number of times to t-->100,000 we discovered:1. Using the function G(x) we hoped the results from the graph after apply the function and correction able to overlap and test with “Scaling and Universality in Transition to Synchronous Chaos with Local-Global Interactions”, but the part which overlapped the measurements was not identical: 2. We can use the significance of the critical point and the Interactive Process to find the approximate value of the critical value up to 4 digits following the decimal point. 3. We can also use the approximate value to find out the range for the simultaneous conditions and the various points on the system itself, as well as obtain a negative correlation between them, and then it can be similarly expressed with using a curve. A computer can calculate values with this kind of enumerating method, even without any special resolution capabilities to quickly obtain large amounts of approximate values of simultaneous conditions, this is especially true when calculating unfamiliar systems. 日常生活中，物件與物件的接觸，彼此會互相影響，有些原本雜亂的系統再經過充裕時間的互相修正後，最後竟能達成同步(例如：鳥群、魚群遷徙的速度、市場價格、行軍步伐…)，有些則不能。因此，我們試著利用描述同步系統的模型，觀察系統同步的過程，並且找出同步的條件。由連結的觀點，我們將Coupled map lattices with global coupling 和Coupled map lattices with intermediate-range 模型的優點整合成Synchronization mode 去模擬同步系統。我們先用小系統(n≦50)得到能印證連結觀點的結果：(一)、系統越雜亂，就需要稍長的時間同步；(二)、個體數越多時，各點需要更大範圍的點數去影響於每單位時間內以及更深的影響才能同步；(三)、起始值隨機影響同步臨界條件並不明顯，在誤差範圍內。更進一步，我們將系統推向n≦400 點,t→100,000 次，我們發現：(一)、在”G(x)”我們希望能將圖形經過函數修正之後能疊和，驗證”Scaling and Universality In Transition to Synchronous Chaos with Local-Global Interactions ”中的結果，但只有部分疊和，尺度不相同；(二)、可以直接利用臨界點的意義用十分逼近法求出臨界值的近似值到小數後四位；(三)、我們用近似值也能發現同步條件與系統各點本身可跳躍的數值範圍是負相關，可用曲線去近似。這種窮舉方式，交由電腦運算，不需要特別的解析能力就能夠快速且大量求得同步條件的近似值，尤其在運算不熟悉的系統時。

本實驗的觀測乃著重於觀測各定點之臭氧濃度與該地天氣因子；如溫度、相對溼度、氣壓、雲量、風速、日照強度等與之比較並控制所有可能的變因，來推測一地空氣污染的程度，並從中思考影響一地臭氧濃度變化的要素。 利用自製的熊本試紙來測量在對流層中臭氧的濃度，進而來推論出我們所設的測站附近的空氣污染程度。 由實驗了解臭氧濃度和其他天氣因子如溫度、相對溼度、風向、風速、日照強度、紫外線強度、工廠作息或交通流量等因素有著很微妙的關係。 最後，我們歸納出在做此實驗時所遇到的相關問題與解決方法。 This experimentation is about the ozone of troposphere. We try to find out how the weather elements affect the ozone consistency (for example: air temperature, relative humidity, air pressure, cloudage, wind speed, solar insolation), and to discover the relation between the ozone consistency and the air pollution. We use the test paper which is made by ourselves to measure the ozone consistency of troposphere, so that we con use the date to infer the air pollution level at the area where we conduct our tests. According to our experiment, we find out the ozone consistency and other weather elements (ex: air temperature, relative humidity, air pressure, cloudage, wind speed, solar insolation or traffic), have some delicate relations with each other. Finally, we conclude all the relative problems we face in this experiment and their solutions.

在綠色能源中太陽能的利用充滿了無限的機會，其中利用太陽熱能發電的太陽能煙囪觀念有很大的潛力。在本研究中，我們以實驗的方法討論煙囪高度、入風口大小、管型等因素對solar chimney 效益的影響，發現就原先的觀念設計中，有相當大的改進空間。整體實驗而言，所改變的各項變數中，以管型之改變有最大的改進效益。就同長度直管與漸擴管而言，漸擴管在風速上有明顯改進效果，且以流速與截面積換算成效率，較原直管設計之效率高出約20 倍，因此推測漸擴管應用在現行之solar chimney 以改進效能是極有可行性的。研究中也發現煙囪管壁的熱傳導也會影響氣體的總體流動，使效率降低。相信此實驗之數據對日後嘗試對solar chimney 進行改進的研究者有相當之參考價值。Solar energy has a great market potential among many clean energies. The new solar chimney concept using solar thermal power in power generation may have a bright future. Experimental work was performed to study the energy conversion characteristics of a solar chimney. The air moving capability and the influences of chimney height, the shape of chimney and air entrance dimension were studied. It was found that there is a great room to improve the current solar chimney design and thus the efficiency. Overall speaking, the chimney pipe geometry may have the most significant impact on the improvement of performance. A diverged pipe configuration can induce nearly 20 times more flow than a traditional straight pipe. Another finding is the heat transfer effect on the chimney pipe may have the effect in reducing the flow. It is believed that the present study0 is valuable for those people in designing a future solar chimney.

A pair of bacterial two-component system RssB-RssA was cooperated into Serratia marcescens for toxicity phenolic compound detection. First step of this study, E coli was used to accept the plasmid and certified by fluorescent. Then transfer the system from E coli into Serratia marcescens. Finally, 7 kinds of chemical, included phenol, benzene, toluene, xylenes, 4-chlorotoluene, 2-nitrotoluene, and kerosene, were used to check the sensitivity of this gene modified Serratia marcescens line. The results showed that this gene modified Serratia marcescens line had good performances and responses to those chemicals. 本實驗是以一受到二元訊號傳遞系統調控的發光基因重組質體，送入黏質色拉雷菌中，並以製備好的菌株進行毒性化合物之測試。在實驗的第一階段，我們將重組質體送入大腸桿菌內，並以其發光的有無來判斷是否達到送入的目的，其後再以電泳法確認各基因片段是否正確。第二階段再以相同的方法將選殖好的重組發光質體送入黏質色拉雷菌。第三階段，以發光重組菌針對酚、苯、甲苯、二甲苯、4-氯甲苯、2-硝基甲苯及煤油進行發光測試。結果方面，我們發現黏質色拉雷菌發光重組菌對於這一系列的酚環類化合物的確具有相當高的敏感度。

We investigate the machinery producing successive Simpson’s paradoxical reverse. Taking advantage of algebraic and geometric techniques, we obtain the following results. Take playing baseball for example. In our study, we find that Simpson’s paradox only occurs when the hitter’s hits over 3 times in one game. Set n equal to the times I will hit in one game. If my batting average in each game is at least(n ?1)/2 times higher than the others’; then I am sure that my total batting average would not be invert by the others. In order to find how many the lattice points in the triangle, we use Pick’s formula. But sometimes, the Pick’s formula is not appropriate to triangles whose vertex are not all lattice points. So we develop New Pick’s formula to estimate the number of lattice points in such kind of triangles. Besides, we also find an iterative algorithm to produce successive “Simpson reverse” phenomenon by using C++ language, and we can therefore produce as many “Simpson’s set of four sequences” terms as we like(not beyond the computers’ upper limit).Moreover, if both sequences of ratios converge, then they must have the same limit.我們探討了一般人乍看之下顯得頗弔詭的辛普森詭論。我們配合GSP 作圖，用解析幾何、設立直角座標系和C++ 程式的運算，找出在特殊情況下或一般情況下所產生的辛普森數列組和特殊的性質，並且以棒球場上的打擊率為例子來做印證。通常一場棒球賽中，每個人平均上場3 次～4 次，經過我們的討論，發現要發生逆轉的機會只有在上場達到4 次或以上時才會發生。?了求出在直角座標系中可以滿足的格子點個數，我們用了Pick公式，但?了更準確的估計，我們引進了虛點的概念，重新推導出了新Pick 公式。另外，我們還發現，假設兩個人上場比賽，若打了2 場，且每場最多上場打擊K 次，其中的一個人的打擊率只要是另一個人的(k-1)/2倍以上就保證不會被逆轉。我們又找到了連續產生辛普森逆轉的演算法，利用C++ 寫出程式，經由演算法和遞迴式，製造出項數可任意多(只要電腦能夠承受)的辛普森數列組，且我們發現若兩個比值數列接收斂，則極限趨近於同一個數值。

In this study, we try to know how ectopic eye genes: eyeless(ey), eye gone(eyg), twin of eyeless(toy), twin of eye gone(toe) act cooperatively, and look for some unknown genes which affect the function of eyg. First, through human trans gene screening, we find two human genes change the phenotype of ey>eyg into dorsal out-growth when they co-express with eyg (ey>eyg+X). It means the two genes may relate to cell proliferation. Second, by sequencing the insert genes of mutant fly which was found by EP screening, the result shows the site of the insertion is the same as effete (eff) gene. eff translated wrong proteins which differ from functional ubiquitin-conjugating enzyme may be the major cause of the mutant eye . 本研究係探討果蠅複眼異位基因eyeless(ey)、eye gone(eyg)、twin of eyeless(toy)、 twin of eye gone(toe)間的協同作用，並尋找與eyg 有交互作用的基因、突變株。藉由人類基因轉殖篩選，找到兩株人類基因轉殖株，當其與eyg 共同表現時(ey>eyg+X)，會改變ey>eyg 的複眼性狀，造成dorsal out-growth，顯示這兩個基因可能與細胞增生有關，此外，藉由EP screening 複眼發生突變的果蠅之UAS 下游基因經比對後，位置與effete（eff）部分契合，推測複眼發生突變的原因是eff 的功能發生異常，致使細胞內蛋白質代謝失常所致。

本研究（超音波霧化降溫研究）由二實驗組成。實驗一主要針對超音波霧化器（以下簡稱霧化器）之造霧性能進行探討；實驗二則為霧化器之降溫應用。實驗一以改良傳統造霧方式，進而維持最佳造霧效果為主。由於先前的霧化方式是直接放置霧化器於水面，致使最佳霧化水深因霧氣蒸散、水位下降而無法維持；所以在實驗一裡，我們針對霧化器的使用設計一套「漂浮造霧法」：本法運用浮體使霧化器懸於水面，和水面等起伏，使霧化器底部距水面高度不變，藉以維持最佳造霧水深、造霧效果。實驗二乃霧化降溫之探討。本實驗在相同的霧化量下，操縱風速和接觸表面積的差異；利用霧、氣接觸面積與蒸散速率呈正向關係的原理，找出最佳的降溫條件。同時，也期待在兼顧環保的前提下，將之應用於未來開放空間的降溫。The research（Heat Control by Supersonic Vaporization）includes two experiments. One is focused on atomized effect of Supersonic Vaporization（so-called Atomizer）; the other is about applying atomizer to temperature decrease. Exp.1 adapts formal way of atomization. Since previous way of atomization is to put atomizer directly on the water, making the change of atomizer’s distance from water as water evaporates, Exp.1 creates a way called “Floating”. In Floating, atomizer is suspended in a float; constantly keeps the bottom of atomizer from same distance from surface of water. Thus, no matter how much volume of water is evaporated, the best depth of water for atomization and also, the best atomized condition, could stay. Exp2 inquires in relation between atomization and temperature decrease. In Exp2, the atomized volume is fixed, while wind speed and air-contact area are mastered elements. By the theory that, “the wider contact area is, the more efficiently water evaporates,” we could manage out the best condition in temperature decrease. In that way, with the theory practiced, this research, considering environmental case, is supposed to be applied to open-air area one day.

臉部皮膚會長出小小骨頭喔！皮膚多發性粟粒型骨瘤的發現，X光顯像，治病機轉與雷射在治療上的應用。本篇研究是探討一種特殊又不易偵測的骨瘤，皮膚多發性粟粒型骨瘤(MMOC)，利用各種X光顯像技術，應用在痤瘡病患，偵測其分佈、發生率和疾病之可能相關；並利用組織病理發現去推測致病機轉；且利用各種雷射光，在體內與體外進行治療性的探索，並獲致重要的結論如下：(1)MMOC非常常見，每個人都有可能發生，但臨床不易被偵測，跟性別無關，但與年齡增長成正相關；(2)病灶分佈包括額頭、眼皮、鼻子、臉頰及頸部，與痤瘡的病灶分佈十分類似，但與痤瘡的疾病活性與疤痕的嚴重度並無相關。(3)利用乳房攝影的斜切照影技術，是最簡易有效的偵測方式。(4)病理組織中有些皮膚腫瘤伴有MMOC存在，並非此腫瘤有其特異性。(5)MMOC是一個因為皮膚毛囊皮脂腺在不明顯的發炎下所造成的轉化型骨形成反應。(6)紅寶石雷射及銣-雅鉻雷射對色素性骨瘤是一有效的去除技術。鉺-亞鉻雷射及二氧化碳雷射磨皮技術，對嚴重痤瘡疤痕並有MMOC患者，亦為一良好治療方式。Multiple Miliary Osteoma Cutis(MMOC) is a kind of special condition and difficult to detect clinically. By using different kinds of X-ray techniques and compared the clinical data from the patients with acne of face, by observing the changes of skin tissue specimens for searching the possible mechanism of osteogenesis and by using scanning electron microscopic observation and energy dispersive Xray analysis for evaluating the biophysical effects on osteoma after Ruby, ND-YAG, Erbium:YAG or CO2 Laser irradiation, we concluded that: MMOC, a very common condition, may develop in everyone. MMOC can be easily demonstrated by the modified mammographic technique. The density of calcification in MMOC is not related to the sex of patients, the activity of acne, and the severity of atrophic scar but correlated with the age of the patients. MMOC, a non-specific condition, results from metaplastic ossification occurring within preexisting subclinical inflammatory processes of the pilosebaceous unit and may be found incidentally in different kinds of facial tumor. Ruby or ND-YAG laser may have some explosive effect on pigmented MMOC. CO2 or Erbium:YAG laser dermabrasion can be used to treat MMOC with acne scar.
