SCM440, which is widely used as the diesel engine piston of vessel, has been hardened by a $CO_2$ laser with the wavelength of $10.6{\mu}m$. Laser hardening experiment has been carried out for the condition of a laser power 1kW, the travel speed between 0.4 and 1.5m/min, and a rectangular-Gaussian beam. Residual stress has been measured by using middle point technique of half value width of X-ray diffraction method. It was found that the compressive residual stress with the range between 400 and 600MHz has distributed in the laser hardening zones and the tensile residual stress between 100 and 200MHz has distributed in the boundary of hardening zones.

Objectives It is very important to diagnose Sasang Constitution (SC) correctly. The aim of this study was to reveal the concordance and validity of the specialists in Sasang Constitutional Medicine (SCM). Methods Three experts who had more than 5 years of experience and used more than 90% of Sasang Constitutional prescription in clinical practice of SCM participated in this study. The data composed of body shape, face, voice, temperament and physio-pathological symptoms were collected in the Korea Constitutional Multicenter Bank and 81 subjects' data were extracted randomly. The experts reviewed all 81 subjects data independently. Kappa analysis was conducted. Results 1) The concordance is from 52.5% to 68.4% among three experts. 2) The validity between individual expert and gold standard is from 54.3% to 63% and Kappa's coefficients are from 0.283 to 0.421. 3) The validity is from 68.5% to 70.7% when two or three experts agree the Sasang constitution independently and 75.7% when all of experts agree it. Conclusions The concordance and validity of experts in SCM seems to be moderate. We think further study is needed.

1. Objectives: This research was proposed to reinterpret "Soeumin Bumron(少陰人 泛論)"through development of Soeumin exterior disease in Sasang Constitutional Medicine(SCM). 2. Methods: We chronically compared the conceptions, symptoms, mechanisms and treatments of Soeumin exterior disease from "Donguisusebowon-GabObon(東醫壽世保元甲午本)"(DGO) to " "Donguisusebowon-ShinChukbon(東醫壽世保元辛丑本)"(DSC) 3. Results and Conclusions: (1) The classification standard of Soeumin exterior disease was different in DGO and DSC. (2) Soeumin exterior disease classified Taeyang Disease(太陽病), Yangmyoung Disease(陽明病) in DGO and Ulkwang-syndrome(鬱狂證), Mangyang-syndrome(亡陽證) in DSC. (3) Based on the changes of understanding about Soeumin exterior disease from DGO to DSC, we attempted to reinterpret "Soeumin Bumron(少陰人 泛論)" in view of DSC. In view of DSC, the classification standard of Soeumin exterior disease focused on Warm Yang Qi(陽煖之氣), Healthy energy(保命之主) of Soeumin.

SCM 21 and D.P steel were carburized in vacuum using prophane at a temperature ranging from 1228k to 1308k under a gas pressure ranging from 21.3kpa to 61.8kpa, and the following results were obrained. 1) D.P. steel has considerable efficiency in depressing the grain growth during the high temperature carburizing and it has fine structure even at 1268k for 14.4ks when carburizied. Therefore this steel is expected to be suitable for vacuum carburizing at a high temperature. 2) Case depth was increased as the carburizing temperature increases and it was 3.2mm at max, temperature of 1308k, for max, time of 14.4ks and under max, pressure of 61.8kpa. Thus vacuum-carburizing was considered effective for the materials which need case depth, which is necessary for machine structure use. 3) The rate of case depth of SCM 21 was faster than D.P. steel under same carburizing conditions and the increasing rate of the case depth was constant. 4) Case depth was increased as the gas pressure becomes high under same carburizing temperature. 5) Case carbon concentration, $C_s$, of SCM 21 obeys to a formula, $$C_s=kt^{1/2}+C_0$$ Where k is $2.15{\times}10^{-2}$($wt%.S^{-1/2}$) and this value is a little bit lower than that of SNCM 815.

Objectives . The types of Sasang constitutional medicine (SCM) have definite effect on response to herbal drugs. The majority of human P45O dependent xenobiotic metabolism is carried out by polymorphic enzymes which can cause abolished, altered or enhanced metabolism. Therefore, we evaluated the relation of major CYP2C19, 2D6 polymorphism with Sasang types. Methods : 214 healthy subjects were recruited with informed consent; 172 among them had Sasang diagnosis by QSCC2. CYP2D6, 2C19 polymorphism were determined by PCR-RFLP method. Results : None of the Sasang types showed significant difference in CYP2D6, 2C19 polymorphism. However, the Tae-um type showed relatively low frequency of CYP2D6 $^{*}$10/$^{*}$10 polymorphisms with low activity (p=0.110). In the So-yang type, specific $^{*}$3/$^{*}$3 genotype which is a poor metabolizer of CYP2C19$^{*}$3 was detected (p=0.078).Conclusion . These results suggest that the Tae-um type which is said to have high liver function in SCM has the tendency of high drug-metabolizing enzyme activity. With further study, the CYP polymorphism could serve as a scientific tool for SCM diagnosis.

1. Objectives: This study examines the pathologies that originate from a Common Root Pathologic Category(CRPC; 同出一屬) in the Soyangin that are suggested in the Sasang Constitutional Medicine(SCM). 2. Methods: The changes in concepts and perceptions on the Soyangin pathologies were compared across the different editions of Donguisusebowon, "Donguisusebowon, Gabo edition(東醫壽世保元甲午本) (DGO)" and "Donguisusebowon, Sinchuk edition (東醫壽世保元辛丑本) (DSC)". 3. Results and Conclusions: The Soyangin pathologies originating from a CRPC that are described in Donguisusebowon are actually detailed classifications of the Yin-deficiency Diurnal-heat symptomatology (陰虛午熱證) and the Chest-congestion symptomatology (結胸證). Lee Jema had introduced the concept of "Common Root Pathologic Category(CRPC)" to approach pathologies of similar exterior/interior classification or severity stage (mild/moderate/severe/critical) by combining them in a comprehensive, integrative pathology system. This comprehensive approach, which promotes better understanding of the Soyangin pathology and maximizes the therapeutic efficiency of SCM, constitutes the "Comprehensive Therapeutic Methodology" that is the hallmark of Sasang therapy.

1. Objectives This study is purposed to find a dietary treatment of Taeyangin in the ${\ulcorner}$Sik Ryo Chan yo(食療纂要)${\lrcorner}$(1460). 2. Methods It was researched as bibliographic study with ${\ulcorner}$Sik Ryo Chan YO${\lrcorner}$ of the oldest Korean book concerned about a dietary treatment and ${\ulcorner}$Hyangyakjipseongbang(鄕藥集成方)${\lrcorner}$ ${\ulcorner}$Euibangyoochui(醫方類聚 )${\ulcorner}$ etc. 3. Results and Conclusions (1) ${\ulcorner}$Hae Dong Moon Hun Chong Rok(海東文獻總錄)${\lrcorner}$ misquoted ‘Five Vegetable(五菜)’ written in ${\ulcorner}$Sik Ryo Chan YO${\lrcorner}$ as 'One leaf(一葉)'. (2) The efficacy of persimmon, Mo Gwa, Oh Ga Pi(the root bark of various araliaceous shrubs), Crucian, Ju Du Kang, Watershied plant(Brassenia purpurea) in this book are the same or similar to those of ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$ and ${\ulcorner}$Dongmu Yugo${\lrcorner}$. But some of them are represented as having different properities in Sasang Constitutional Medicine(SCM) and ${\ulcorner}$Sik Ryo Chan YO${\lrcorner}$. For example, dried persimmon is used for the treatment of deafness, Crucian for asthma and Song Jul(松節) for bruises in ${\ulcorner}$Sik Ryo Chan Yo${\lrcorner}$ but SCM. (3) This book doesn`t have a definite expression about Sasangin, but it contains documents of clinical cases. So it seems that this book would somewhat affect to SCM after ages.

스토리지 클래스 메모리(SCM)는 메모리와 스토리지의 장점을 동시에 가지고 있기 때문에 기존의 스토리지를 대체할 차세대 스토리지로 주목 받고 있다. 하지만 현재까지 제안된 SCM 전용 파일시스템은 데이터 일관성을 충분히 보장하지 않거나 혹은 보장될 경우, 과도한 일관성 유지 비용을 발생시키는 문제점을 지니고 있다. 본 논문에서는 보편적으로 사용하는 WAL(Write Ahead Logging) 방식의 일관성 유지 기법 대신 롤백-복구 방식을 이용하여, 블록내의 변경되는 데이터의 비율에 따라 로그 데이터 기록 방식을 변경하는 데이터 일관성 유지 기법을 제안한다. 본 기법은 데이터 일관성 손실 없이 로그 데이터의 크기를 줄여 데이터 쓰기 및 동기화 비용을 최소화시킬 수 있다. 제안한 기법을 평가하기 위해 리눅스 3.10.2 상에 구현하여 성능을 측정한 결과, 다른 일관성 유지기법에 비해 평균적으로 9배 정도의 데이터 쓰기 성능이 향상됨을 볼 수 있었다.

A cross-sectional study was undertaken to report prevalence and to identify risk factors of subclinical mastitis of dairy cattle in Sylhet district of Bangladesh. Among 325 dairy farms of the district 12 farms(3.7%) were selected conveniently for this study. All the dairy cows of the 12 farms were selected for sample collection. Fresh milk samples from each of the selected dairy cows were collected aseptically in separate sterilized test tube as RF, RH, LF and LH quarter of the udder. Rapid modified White Side Test(WST) was used to detect subclinical mastitis(SCM). Results of WST and data derived from filled in questionnaire were entered in Microsoft Excel 2003 and transferred to $STATA^{(R)}$, version 8.0/Intercooled(Stata Corporation, Texas, USA, 2003). The overall prevalence of SCM and its distribution in different categories of variables in cow and their exact binomial 95% confidence intervals were calculated in $STATA^{(R)}$. Simple bivariable associations among independent variables were investigated by $x^2$ test in $STATA^{(R)}$. Multiple logistic regression analysis with backward elimination method was used to identify risk factors of SCM. To identify significant variation in quarter SCM, linear regression analysis was performed after arcsine transformation of the data. The overall prevalence of SCM found in this study is 54%. Dairy cows with teat lesions had significantly increased SCM(OR=12342, P value=0.000, 95% CI=762, 199798) than others without teat lesions. The Holstein Friesian X Jersey X Sahiwal breed has significantly decreased(OR=0.18, p=0.03, 95% CI 0.04, 0.85) SCM than other breeds. The prevalence of SCM found in this study is in agreement with others. The injury in the teat increases the probability of getting infected with microbes and thereby mastitis. If the prevalence of teat lesion can be decreased the probability of subclinical mastitis will also be decreased. The negatively associated Holstein Friesian X Jersey X Sahiwall breed may help in planning mastitis control program if this finding can be validated by a more powerful case-control or cohort study design.
