이 논문에서는 초기 미주 지역 이주민인 김장연 씨에게 고국의 가족들이 1914년부터 1920년까지 보낸 일련의 한글 편지들을 판독하고 이를 통하여 20세기 초반 미주 지역 이민사의 편린과 고국에 남겨진 김장연 씨 일가의 사연을 알아보고자 하였다. 이 편지들은 한반도에서 미주 지역으로 보내진 초기 편지들로 이를 통해 김장연 씨 일가를 중심으로 한 미주 지역에서의 이주민의 생활의 편린을 확인할 수 있었고 문헌 자료를 확인하기 어려운 일제 초기 일반인의 삶과 언어 생활을 엿볼 수 있는 기초 자료를 구축할 수 있었다. 무엇보다 이 편지 자료들을 통해서 수원 지역 일대의 실제 지명과 다양한 언어 생활, 미주 지역 이민들과의 교류 내용 등을 알 수 있어서 20세기 초반의 이민사에서 중요한 한글 필사자료 및 언어 자료를 확보할 수 있었다. 이밖에 편지 속 등장인물들의 행적들을 <공립신보>, <신한민보> 등 관련 기록을 통해 확인할 수 있었고 감리교단 수원지역 순행 전도사의 활동 기록 등을 확인할 수 있었다. This paper aims to introduce Hangul letters which were written by Kim Chang Yeon`s family and emphasize their values as precious materials for Korean language research. Kim`s family in Korea sent letters to Kim Chang Yeon in America from 1914~1920, and these letters includes the life of the first Korean immigrants generations and fill the missing part of Korean language in this period of time of Korea. Based on these letters which were sent from Suwon area, place names of Suwon area and cultural and linguistic connections between Koreans and Korean immigrants can be studied. These letters will be provided to those who studies Korean language as important Hangul written materials that shows many aspects of Korean language. Besides, people`s past in letters such as Kim Byung Kwon, Kim Sun Kwon, Kim Sung Sik, Choi Sim Sun(Kim Chang Yeon`s wife), Kim Rose(Kim Chang Yeon`s elder daughter, Kim Eva(Kim Chang Yeon`s second daughter, Kim Young(Kim Chang Yeon`s elder son), Kim Edward(Kim Chang Yeon`s second son) was checked out in this paper. Finding out what Kim Byung Kwon`s had done as a methodist missionary of Suwon area is a collateral outcome of this study.

Longitudinal data often occur in prospective follow-up studies. Joint model for longitudinal data and failure time has been applied on several works. In this paper, we extend it to the case where longitudinal data involve informative observation time process as well as competing risks survival times. We use a likelihood approach and derive an EM algorithm to obtain maximum likelihood estimate of parameters. A suggested joint model allows us to make inferences for three components: longitudinal outcome, observation time process and competing risk failure time. In addition, we can test the association among these components. In this paper, liver cirrhosis patients' data is analyzed. The relationship between prothrombin times measured at irregular visiting times and drop outs is investigated with a joint model.

Recurrent event data occurs when a subject experience the event of interest several times and has been found in biomedical studies, sociology and engineering. Several diverse approaches have been applied to analyze the recurrent events (Cook and Lawless, 2007). In this study, we analyzed the YTOP(Young Traffic Offenders Program) dataset which consists of 192 drivers with conviction dates by speeding violation and traffic rule violation. We consider a subject-specific effect, frailty, to reflect the individual's driving behavior and extend to time-varying frailty effect. Another feature of this study is about the redefinition of risk set. During the study, subject may be under suspension and this period is regarded as non-risk period. Thus the risk variables are reformatted according to suspension and termination time.

The purposes of this study were 1) to investigate high school girls` overall clothing satisfaction and self concepts, 2) to clarify the relationship between clothing satisfaction and self concept in terms of body cathexis, school achievement and social self-esteem, and 3) to find out the social self-esteem differences among the groups related to the high and low levels of clothing satisfaction, body cathexis as well as school achievement. Body Cathexis was measured by the Secord and Jourard`s Body Cathexis Scale. School achievement and social self-esteem were assessed with the modified questionnaires based on the previous researches. Clothing satisfaction which included 3 aspects was measured by the questionnaires developed for this study. The questionnaire was administered to 464 high school students in Seoul, and the data were analyzed by frequency, t-test, one-way-ANOVA and SNK test, Pearson`s product moment correlation and factor analysis. The results of this study were as follows: 1) High-school girls` body cathexis showed low levels of mean and distribution, wheareas school achievement and social self-esteem showed high levels of those. 2) There were significant positive correlation between clothing satisfaction and all of the self concept variables. In addition, postive correlation were found among the three self concept variables. 3) Three clothing satisfaction factors were emerged and named as clothing possession, clothing selection ability and parent`s clothing restriction. Clothing possession and parent`s clothing restriction were generally satisfied. 4) School achievement was the most influencial variable for the level of social self-esteem. It was thought that body dissatisfaction would be relieved by the high clothing satisfaction.

Interval-censored data are commonly found in studies of diseases that progress without symptoms, which require clinical evaluation for detection. Several techniques have been suggested with independent assumption. However, the assumption will not be valid if observations come from clusters. Furthermore, when the cluster size relates to response variables, commonly used methods can bring biased results. For example, in a study on lymphatic filariasis, a parasitic disease where worms make several nests in the infected person's lymphatic vessels and reside until adulthood, the response variable of interest is the nest-extinction times. Since the extinction times of nests are checked by repeated ultrasound examinations, exact extinction times are not observed. Instead, data are composed of two examination points: the last examination time with living worms and the first examination time with dead worms. Furthermore, as Williamson et al. (2008) pointed out, larger nests show a tendency for low clearance rates. This association has been denoted as an informative cluster size. To analyze the relationship between the numbers of nests and interval-censored nest-extinction times, this study proposes a joint model for the relationship between cluster size and clustered interval-censored failure data.

양극성 장애 (bipolar disorder)는 조증 삽화 (manic episode)와 우울증 삽화 (depression episode)를 반복적으로 경험하는 기분장애이다. 양극성 장애환자에게 우울증은 조증보다 심각한 결과를 가져오며, 치료의 효과를 측정하기도 어렵다고 알려져 있다. 본 연구의 목적은 우울증(depression) 상태에 있는 환자들을 대상으로 항우울제를 사용하여 정상 (normal) 상태로 전환했을 때, 약물의 장기 사용으로 일어날 수 있는 조증 (mania)과 같은 부작용을 통제하고자 한다. 이를 위해 정상 상태에서 조증으로 전환하는데 소요되는 시간의 분포를 추정한다. 본 연구에서는 세 가지 방법, 모수적, 비모수적 그리고 준모수적 방법을 차례대로 적용하였다. 특히 기분 전환의 흐름을 파악하기 위해 3단계 모형을 사용하였다. 예를 들어, Illness-Death 모형하에서 기분 전환의 발생시점에 대한 분포를 추정하기 위해 계수 과정에 의해 기분 전환에 대한 과정을 모형화하였다.

A method has been developed to tune the static stiffness at a rotation joint considering the whole machine tool system by interactive use of finite element method and experiment. This paper describes the procedure of this method and shows the results. The method uses the static experiment on measurement model which is set-up so that the effects of uncertain factors can be excluded. For FEM simulation, the rotation joint model is simplified using only spindle, bearing and spring. At the rotation joint, the damping coefficient is ignored, The spindle and bearing is connected by only spring. By static experiment, 500 N is forced to the front and behind portion of spindle and the deformation is measured by capacitive sensor. The deformation by FEM simulation is extracted with changing the static stiffness from the initial static stiffness considering only rotation joint. The tuning static stiffness is obtained by exploring the static stiffness directly trusting the deformation from the static experiment. Finally, the general tuning method of the static stiffness of machine tool joint is proposed using the force stream and the modal analysis of machine tool.

Ordinary survival analysis cannot be applied when a significant fraction of patients may be cured. A cure rate model is the combination of cure fraction and survival model and can be applied to several types of cancer. In this article, the cure rate model is considered in the interval censored data with a cluster effect. A shared frailty model is introduced to characterize the cluster effect and an EM algorithm is used to estimate parameters. A simulation study is done to evaluate the performance of estimates. The proposed approach is applied to the smoking cessation study in which the event of interest is a smoking relapse. Several covariates (including intensive care) are evaluated to be effective for both the occurrence of relapse and the smoke quitting duration.

Rib structure has been used to bed and column of machine tool to heighten weight stiffness ratio, cost performance and weight saving. In this paper the bed rib structure was estimated with thermal characteristics. Using superposition principle, machine tool designer can describe every complicated heat generation in the machine tool thermal source. As thermal characteristics, thermal deformation of guide rail and column and Maximum-minimum temperature variation were selected. The size, configuration and direction against the thermal loading surface operated to the thermal characteristics. The DB chart was made following rib structure estimating thermal characteristics. With superposition principle and DB chart, machine tool designer can prognosticate the thermal characteristics without FEM analysis to every bed rib structure.

The purposes of this study were 1) to identify the effects of age and sex on adolescent`s psychological characteristics-egocentrism, self-consciousness, body cathexis and clothing behaviors and 2) to identify the effects of psychological characteristics on clothing behaviors in each of the 6 groups classified by sex and age. Egocentrism was measured by Kim`s Imaginary Audience Scale, and body cathexis, by the modified Secord and Jourards Body Cathexis Scale. Buss`s Self-Consciousness Scale was slightly modified to assess public and private self-consciousness, and five aspects of clothing behavior were assessed with the questionmaires from the previous studies. The questionnaire were administered to 713 middle and high school boys and girls, and college students living in Seoul. Data were analyzed by frequency, factor Analysis, two-way ANOVA, and multiple regression analysis. The results of this study were as follows: 1) Four factors of egocentrism were identified Potency, Appearance/populatity, Sympathy and Justice. Four factors of clothing behavior were Clothing exhibition/dressing for others, Clothing interest, Psychological dependence, and Clothing conformity. 2) Sex and age were found to have effects on psychological variables and clothing behaviors of adolescence. Females showed higher egocentrism, selfconsciousness, clothing benaviors, but lower body cathexis than males. The mean scores of egocentrism, self-consciousness, clothing behaviors tended to increase with age. However, high school boys showed unique tendency, as they showed higher scores in those variables than the other two age groups. 3) Egocentrism (Appearance/populality factor) and public selfconsciousness were the most influencial variables on adolescent`s clothing behavior among psychological characteristics. Private self-consciousness was found to be an important variable in explaining Psychological dependence.
