  • Recently, according to the increase of income and development of quality of life, the leisure industry has been developed. In particular, the interest of design and manufacture technology of leisure yacht has significantly increased. However, domestic market of leisure ships is currently in its initiating stage. So research and development for structural strength of leisure yacht need to be investigated. In this study, lug of yacht's mast which is known for a critical damage region is explicitly considered. This paper deals with the estimation of stress concentration factors (SCFs) for lug of yacht's mast depending on dimensions of lug using hot spot stress. Also, SCF formulae is suggested using parametric study.

  • It is desirable that the management of human resources, as a strategy for the competition, should be the necessity for the hotel industries to survive in the rapid change and continuous development In other words, the management of enterprise provides the foundation to form human relationship, just as the hospitality industry operates with human relationship. Here by, all the problems out hotels have faced are that our hotels should look for a new human resources. The control of human resources in hotels means that if does not only satisfy hotels, employees, and guests but improves the personal ability. also it is important for the method of hotel operation as a management. Therefor, hotel managers have to get a good human resources, at the same time, improve the potential ability from them in order to get development for industries and a person. This study in the effective project for the human resources in hotels is relation to the organization of hotel sand he factor of human resources. This research if focused on the property of classification each factor in the control of human resources. according to the classification, the relationship and an effect are commonly made in groups of properties and are named respectively.

  • The development of this inventory for measuring the parenting self-efficacy of Korean mothers took place in Seoul with 473 mothers of 5th and 6th grade children. Means, %, ${\chi}^2$, Cramer's V, Cronbach's ${\alpha}$, Split-half Reliability, factor analysis and Pearson's r were used for data analysis. Five parenting self-efficacy factors were extracted from the 37 items developed for this study. Subscales were General Parenting Self-Efficacy, Health, Communication, Education, and Control. Criterion Validity of the 37 items was confirmed by a significant correlation with the Shin's parenting self-efficacy(r=.71). Internal consistency of this scale was high (Cronbach's ${\alpha}=.92$), including internal reliability of subscales. Factor validity was satisfactory at .65 - .86. These results confirm this scale as a valid and reliable measure of the parenting self-efficacy of Korean mothers.

  • Menu is regarded as the main factor for management of hotel and restaurant. Menu design was affected by many factors, but there are some items should be considered carefully for development of menu, such as a good understandings of consumers' demand. considering of the regional characteristics, establishing of the exact target, and careful thinking of a unit cost. At last, the most important factor is careful evaluation of developed menu and it have to be continuously reformed by feed back of these factors. Food service industries should create an independent menu(including restaurant layout, consumer level, marketing and advertising) rather than copying other restaurant' menu. Also. we have to design an efficient menu with useful information through the best of menu.

  • 유역의 수자원 및 환경 상태에 관련된 문제를 파악하고 관리에 적극적인 참여를 유도하기 위해서는 객관적인 평가수단이 필요하다. 따라서 본 연구에서는 지속가능한 유역관리를 위하여 수계의 중권역별 유역관리 상태를 평가할 수 있는 평가지수를 개발하고 지수의 적용성을 평가하였다. 본 연구에서는 유역조사 자료와 다변량 통계 기법의 하나인 요인분석을 이용하여 유역관리 평가지수를 개발하였다. 또한, 평가지수를 한강수계에 적용하여 중권역별 유역관리 상태를 상대적으로 비교하여 평가하였다. 유역관리 평가지수는 이수관리 평가 세부지수, 치수관리 평가 세부 지수, 수질 및 생태 관리 평가 세부 지수로 구성하였다. 각 평가지수는 요인분석을 통하여 추출된 3개의 지표로 구성이 되어 있으며, 각 지표들은 $3{\sim}5$개의 변수들로 구성되어 있다. 한강수계의 중권역별 유역관리 상태를 평가한 결과, 댐상류에 위치한 중권역에서 다른 중권역들 보다 유역관리지수가 높게 나타났으며, 수계의 최하류에 위치한 중권역에서 다른 유역들 보다 작은 값을 나타냈다.

  • It is essential in evaluating the chronic pain patients that the physician obtain a multiple causative factors including organic, psychological, and socioenvironmental factors. Though these multiple factors are involved in the development of chronic pain syndrome, chronic pain syndrome is not only the sum of the interaction of all of these factors, but is also influenced by the sequelae of chronic pain, which again are organic, psychological, and socioenvironmental in nature. Therefore a systemic approach is probably the best way to asses the role of all of these factors. Furthermore, this approach can provide a framework for understanding chronic pain syndrome, for assessing chronic pain syndrome, for the rational management of chronic pain syndrome, and for the development and testing of hypotheses.

  • Self-esteem and social supports are important variable influencing adjustment to college life. The study aims to identify the factors influencing college students' adjustment moderating effects on social supports. Data were collected from 265 usable questionnaires among college students in Pyeongtek University. Results of a factor analysis yielded three dimensions of self-esteem which were talent/attitude and capacity/pride. And results of factor analysis also yielded three dimensions of social supports which were family, friends, and professor supports. Hierarchical regression analysis revealed that capacity/pride and all of social support factors affected significantly for adjustment to college life. And female and attitude for students' major had a positive affect on adjustment to college life. It was suggested that self-esteem, social supports, and aptitude for students' major should be considered in college management policy.

  • Bone is a dynamic organ that bone remodeling occurs throughout life and involves the process in which the bone matrix is broken down through resorption by osteoclasts and then built back again through bone formation by osteoblasts. Usually these two processes balance each other and a stable level of bone mass is maintained. We here discuss transcription factors involved in regulating the osteoblast differentiation pathway. Runx2 is a transcription factor which is essential in skeletal development by regulating osteoblast differentiation and chondrocyte maturation. Its companion subunit, Cbf${\beta}$ is needed for an early step in osteoblast differentiation pathway. Whereas Osterix(Osx) is a new identified osteoblast-specific transcription factor which is required for the differentiation of preosteoblasts into more mature and functional osteoblasts. We also discuss other transcription factors, Msx1 and 2, Dlx5 and 6, Twist, and Sp3 that affect skeletal patterning and development. Understanding the characteristics of mice in which these transcription factors are inactivated should help define their role in bone physiology and pathology of bone defects.
