So many patterns of the clothing give the specific indication for one's clothing behavior and present the common style for the society. Human being gives the one's free expression and attempts to change the existing cultural environment by the clothing even though human being would be restricted in choosing the clothing within the category of the society & the culture. The value of human being which attempts to escape the restriction through the behavior theory of T. Parsons is analysed and studied. The role of the modern society is being transformed and human being attempts to express one's self through the clothing very strongly. The clothing behavior means the expression of oneself for others. This phenomenon comes from the changing of human being's view of value through the social & cultural environment which give human being the freedom of the individual to choose the various clothing.

The call-attempt behavior in a telecommunications service is influenced by the launch of new services and the choice of subscribers. On Feb 28, 2005, there was a disastrous shut-down of major local electronic switching systems (ESS) due to an abrupt increase of call-attempts. This incident turned out to be a strong proof that appropriate forecasting attempts are necessary not only for the capacity planning of network but also for the quality control of ESS. In this paper, forecasting models are first developed to estimate the daily ESS call-attempts and user retrial rates and then meaningful interpretations of results will follow. Finally future research topics will be presented.

Objectives: We aimed to compare the smoking behaviors in adolescents from monocultural and multicultural families and to evaluate the associations between their smoking behavior and number of suicide attempts. Methods: The data used in this study was collected from The Tenth Korea Youth Risk Behavior Web-based Survey. The differences in the sociodemographic characteristics between the adolescents in the multicultural and monocultural families were analyzed through the ${\chi}^2$-test, and a logistic regression was conducted to evaluate the relationships between the smoking behavior and number of suicide attempts of the adolescents in multicultural families. The process involved an analysis using a complex sample design. Results: There was significant difference in the weighted rates of the current smoking behavior (13.3% vs. 8.4%, p<0.001), experience of violence (6.8% vs. 2.3%, p<0.001), and number of suicide attempts (5.4% vs. 2.7%, p<0.001) between the adolescents from the multicultural and monocultural families. In both groups, the current smoking behavior was associated with the number of suicide attempts (multicultural families OR=6.5, p=0.005; monocultural families OR=1.5, p<0.001). Conclusion: Our results showed that the percentage of current smokers in the adolescents from multicultural families was higher than that in the monocultural families and that current smoking behavior is related to the number of suicide attempts in both groups, after adjustment for age, sex, socioeconomic status, academic achievement, current smoking behavior, depressive mood and experience of violence.

연구목적 본 연구에서는 우울감을 주소로 내원한 청소년을 대상으로 비자살성 자해행동(Non-suicidal Self-Injury, 이하 NSSI) 의 빈도와, NSSI유무에 따른 사회인구학적, 임상적 특성을 비교하고, 이와 연관된 자살시도의 예측인자를 밝히고자 한다. 방 법 총 113명의 우울감을 주소로 내원한 12세에서 18세 청소년을 대상으로, 사회인구학적 특징, 자살행동과 NSSI, 심리상태에 대해 자기보고식 검사도구를 이용하여 평가하였고, 반구조화된 면담도구를 이용하여 정신과적 진단을 하였다. NSSI의 유무에 따라 두 군으로 나누어 이들의 사회인구학적 특징과 임상적 특징을 비교하였고, 로지스틱 회귀분석을 이용하여 유의한 변수 중 자살시도의 예측인자를 분석하였다. 결 과 분석에 포함된 113명의 청소년 중 42.1%에서 NSSI를 보고하였다. NSSI 가 있는 군은 없는 군에 비해 여성이 더 많았고, 우울, 불안 및 자살사고점수가 더 높았다. 자살 시도의 가장 연관성이 높은 예측인자는 NSSI, 가족이나 친구 중 자살/자해 경험, 총 상태불안점수였다[Odds Ratio (OR)=0.05, 95% Confidence Interval (CI)=0.01~0.20, p<0.001 ; OR=0.07, 95% CI=0.01~0.45, p=0.005; OR=1.10, 95% CI=1.02~1.19, p=0.013]. 결 론 본 연구를 통해 우울감을 주소로 병원에 방문한 청소년은 일반인구에 비해 NSSI의 빈도가 3배 정도 더 높고, NSSI가 동반된 경우 자살사고와 불안이 높며 자살시도와도 연관성이 매우 높음을 확인하였다. 본 연구 결과를 통해 병원에 방문한 우울한 청소년의 경우, NSSI에 대한 평가의 반드시 포함해야 하며 청소년 대상 자살예방프로그램 개발 시 NSSI에 대한 평가 및 접근을 반드시 포함해야 할 것으로 생각된다.

There have been several attempts to describe the recent phonemona of e-tailing and the competition of e-tailers with traditional retailers. However, it appears that the previous models exhibit some shortcomings. With an extension of the well-known circular city model, this paper attempts to relax those limiting assumptions and addresses various issues around electronic commerce: whether e-tailing will eventually drive out traditional retailing, whether e-tailing will necessarily increase competition and lead to lower prices, and whether all the consumers will be better off with more alternatives to choose from.

Non-suicidal self-injury (NSSI) has been noted as a significant risk factor for possible suicide attempts. According to the Interpersonal Psychological Theory of Suicide, individuals can attempt suicide after they have acquired the capability to commit it. The acquired capability for suicide can be defined as one's habituated level to the pain and fear associated with suicidal behaviors. This is obtained through constant exposure to painful and provocative events, NSSIs being a prime example. This article reviews prior related studies to determine the extent to which the acquired capability for suicide can be utilized as a predictive factor for fatal suicide attempts following NSSIs. Our review finds a total of 11 studies that directly or indirectly support the claim that the acquired capability for suicide should be considered as a relevant factor linking NSSIs and suicide attempts. Given that NSSIs are most frequently observed in clinical settings, our findings suggest that the acquired capability for suicide will be a useful indicator for clinicians to predict the risk of future suicide attempts by patients.

Background: Tobacco use and quit attempts are two key indicators of the Global Adult Tobacco Survey (GATS) that assess quit attempts among current as well as former tobacco users. The relevant data have inherent policy implications for tobacco cessation programme evaluation. This study aimed to review the concepts of quit attempt assessment and quantifying invalid responses considering GATS-India data. Materials and Methods: GATS assessment of tobacco use and quit attempts were examined in the current literature. Two categories of invalid responses were identified by stratified analysis of the duration of last quit attempt among current users and duration of abstinence among former users. Category A included absolute invalid responses when time-frame of assessment of current tobacco use and less than former tobacco use were violated. Category B included responses that violated the unit of measurement of time. Results: Current daily use, current less than daily use and former use in GATS were imprecisely defined with overlapping of time-frame of assessment. Overall responses of 3,102 current smokers, 4,036 current smokeless users, 1,904 former smokers and 1,343 former smokeless users were analyzed to quantify invalid responses. Analysis indicated overall 21.2% (category A: 7.32%; category B: 17.7%) and 22.7% (category A: 8.05%; category B: 18.1%) invalid responses among current smokers and smokeless users respectively regarding their duration of last quit attempt. Similarly overall 6.62% (category A: 4.7%; category B: 2.3%) and 10.6% (category A: 8.6%; category B: 3.5%) invalid responses were identified among former smokers and smokeless users respectively regarding their duration of abstinence. Conclusions: High invalid responses for a single assessment are due to the imprecise definition of current use, former use and quit attempt; and failure to utilize opportunity of direct data entry interface use during the survey to validate responses instantly. Redefining tobacco use and quit attempts considering an appropriate timeframe would reduce invalid responses.

Objectives: To identify bacterial contamination rates of laryngoscope blades and handles stored in emergency crash carts by hospital and area according to the frequency of intubation attempts. Methods: One hundred forty-eight handles and 71 blades deemed ready for patient use from two tertiary hospitals were sampled with sterile swabs using a standardized rolling technique. Samples were considered negative (not contaminated) if no colonies were present on the blood agar plate after an 18-hour incubation period. Samples were stratified by hospital and according to the frequency of intubation attempts (10 attempts per year) using the ${\chi}^2-test$ and Fisher exact test. Results: One or more species of bacteria were isolated from 4 (5.6%) handle tops, 20 (28.2%) handles with knurled surfaces, and 27 (18.2%) blades. No significant differences were found in microbial contamination levels on the handle tops and blades between the two hospitals and two areas according to the frequency of intubation attempts. However, significant differences were found between the two hospitals and two areas in the level of microbial contamination on the handles with knurled surfaces (p<0.05). Conclusions: Protocols and policies must be reviewed to standardize procedures to clean and disinfect laryngoscope blades and handles; handles should be re-designed to eliminate points of contact with the blade; and single-use, one-piece laryngoscopes should be introduced.
