The goal of this study was to provide basic data for the future development of dietary life education in elementary schools by understanding the current conditions of the program after the execution of the Dietary Life Education Support Act. We conducted a survey to understand dietary teachers' recognition of dietary life education in elementary schools. We found that teachers' recognition was low and that dietary life education in elementary schools is still carried out indirectly by focusing on nutrition knowledge. Dietary life education is carried out during lunch time and dietary life-related class hours. However teachers of lower class levels did not have any practical subject related to dietary life and responded that a lack of time devoted to dietary life education was the biggest problem with the program. Most teachers responded that dietary life education in elementary schools is necessary for the formation of students' sound dietary habits, and that the development of a system of teachers directly responsible for dietary life education is necessary. In the past, dietary life education has typically been carried out at home, but now schools are required to play a role because of family nuclearization and the increase in working couples. Therefore, to revitalize dietary life education programs in elementary schools according to the Dietary Life Education Support Act, we suggest more systematic and segmentalized studies.

This study presents a more comprehensive approach to investigate how Emotional Intelligence (EI) is associated with performance. Previous research has revealed that EI is related to positive outcomes such as better performance, life satisfaction and career success. However, in most research of EI, this factor has been investigated independently from the effect of contextual factors and other individual characteristics. This study extended the research on the impact of EI on student performance by simultaneously examining the impact of EI, individual factors - (1) Perseverance of Effort, (2) Goal Consistency and (3) Goal Clarity and learning environment factors - Program Fit in one study. The results based on the data collected from 1,117 students in Vietnam largely support the hypothesis that that EI was an important but not the only factor affecting the student performance. MANOVA and post-hoc analysis indicated that both individual and environmental factors better predicted performance than EI could. These results suggest that the impact of EI on individual performance is more complicated than what we have already known. Future study is encouraged to investigate both the mechanism through which EI impact individual performance and the interaction between EI and other factors that moderate the EI - performance relationship.

Korean societies have been experiencing the wholesale structural changes in the rapid currents of recent openness, globalization and democratization, which effect much more heavily in rural areas than in urban areas, so rural recomposition works being an important national concern. In order to systematically reconstruct the rural structure, the decision makers, with a four step hierarchy of rural resident-residents group-community-region, should be endowed with the objective judgement on basic elements of resource potentialities under their control. In this process. rational resource evaluation works would be firstly necessiated from expert groups. Based on the view mentioned above, this study principally aimed at developing a rational evaluation framework for rural resources. For that objective, the first step of the study pigeonholed the total resources items identifiable in rural areas from the existing study results, spatial planning and field surveying data. After then, using the formalized classification criteria of resources items, a tentative goal system for rural resources evaluation was proposed and the final one determined through expert-group checking. The results obtained during the study are summarized as follows ; 1. Using the existing examples of resources identification/classification and the basic data list for county-level development planning as the principal reference ones, total rural resources elements were classified into 3 constituent units : land, natural environment and human resources, which correspond to places to work, to play and to live, respectively, as 3 constituent ones of life-supporting space. 2. Three characteristic areal types were adopted to represent the total rural areas : lowland, upland and seashore areas, and also 3 practical use types to represent the objectives of resources evaluation systems : for land use planning, natural conservation policy and village improvement planning. Thus 9 different types of goal system for resources evaluation were developed(each system by 3 areal typesX3 practical use types) 3. Each goal system has 3-tier classification steps from the higher, middle and lower one. The higher and middle steps should contain equally applicable components to all the rural areas, of which allowable number being around 3 and 4 respectively. However the lower step would contain detailed sub-components changeable to areal characteristics of which allowable number being around 7.

A one-shot system (device) refers to a system that is stored for a long period of time and is then disposed of after a single mission because it is accompanied by a chemical reaction or physical destruction when it operates, such as shells, munitions in a defense weapon system and automobile airbags. Because these systems are primarily related with safety and life, it is required to maintain a high level of storage reliability. Storage reliability is the probability that the system will operate at a particular point in time after storage. Since the stored one-shot system can be confirmed only through inspection, periodic inspection and maintenance should be performed to maintain a high level of storage reliability. Since the one-shot system is characterized by a large loss in the event of a failure, it is necessary to determine an appropriate inspection period to maintain the storage reliability above the reliability goal. In this study, we propose an optimal inspection policy that minimizes the total cost while exceeding the reliability goal that the storage reliability is set in advance for the one-shot system in which periodic inspections are performed. We assume that the failure time is the Weibull distribution. And the cost model is presented considering the existing storage reliability model by Martinez and Kim et al. The cost components to be included in the cost model are the cost of inspection $c_1$, the cost of loss per unit time between failure and detection $c_2$, the cost of minimum repair of the detected breakdown of units $c_3$, and the overhaul cost $c_4$ of $R_s{\leq}R_g$. And in this paper, we will determine the optimal inspection policy to find the inspection period and number of tests that minimize the expected cost per unit time from the finite lifetime to the overhaul. Compare them through numerical examples.

This study developed and proposed a lesson plan for the area of “Human development and family relationship”in secondary home economics curriculum. In current educational practice in secondary home economics curriculum, the employed goal and the nature of home economics are neither stated specifically nor closely interrelated. This problem has led us not being able to achieve pursuing goal of home economics education and to employ appropriate teaching methods. In view of this situation, the purpose of this study was to propose a lesson plan reflecting the contents and teaching methods to overcome difficulties and inefficiency in the current practice of secondary home economics education. The theoretical background of the lesson plan was based on the Marjorie M. Brown’s philosophy of home economics which can be summerized as follows: 1. The goal of home economics is to help individuals and families to become autonomous in their own family life and to be more capable of interacting with others in behalf of well-being of the family and of social evolution toward a free society. 2. The characteristics of home economics is conceptualized as practical science and personal service profession. 3. the nature of problems which home economics should deal with is perennial and practial. 4. Practial reasoning composed of historical understanding, critical action, and reflective thinking is appropriate for the previously mentioned goal and characteristics of home economics and for dealing with perennial practial problems. The lesson plan was proposed for one of perennial problem, “How should we understand, create, and maintain our family culture\ulcorner”by employing practial reasoning and teaching models such as “role play”and “classroom meeting.”

In this paper, a versatile multi-criteria optimization concept for fatigue life prediction is introduced. Multi-criteria decision making in engineering design refers to obtaining a preferred optimal solution in the context of conflicting design objectives. Compromise decision support problems are used to model engineering decisions involving multiple trade-offs. These methods typically rely on a summation of weighted attributes to accomplish trade-offs among competing objectives. This paper gives an interpretation of the decision parameters as governing both the relative importance of the attributes and the degree of compensation between them. The approach utilizes a response surface model, the compromise decision support problem, which is a multi-objective formulation based on goal programming. Examples illustrate the concepts and demonstrate their applicability.

The main goal of this paper is to establish an interference tolerance for determining optimal amount of clearance in the shaft-bearing system supported by radial ball bearings. The 2-D frictional contact model was employed for the FE analysis between the shaft and the inner raceway. Several examples were simulated using different material properties for the solid shaft. Efforts were focused on the deformation applied in the radial direction to select suitable bearings. The analysis results showed that the initial axial preload applied on the bearings plays a significant role to reduce bearing fatigue life. The proposed design parameters obtained by numerical simulations can approximately predict a rate of bearing life reduction as a function of shaft diameter ratio. This analysis can also be used to calculate the optimal initial radial clearance in order to obtain a shaft-bearing system design for high accuracy and long life.

The primary purpose of this study is to explore the daily lives of gay men and assess their interests in fashion and appearance management with the goal of better understanding the roles or meanings of fashion in their lives. In-depth interview method was adopted and the responses were analyzed qualitatively. Six homosexual men were interviewed, and the outcome of each conversation was recorded and analyzed; each man had a different background and thus showed different behavioral patterns. The life patterns distinct to Korean gays, the importance the highly patriarchal society places on family lineage and mandatory military service, for example, were discussed. Even though the interviewees asserted that their interests in fashion is not related to their sexual orientation, fashion was utilized as a means of self-expression by these gay men.

Apartment Housing in Korea has been developed rapidly and settled as a main housing form for short period, 40 years. In spite of increase of the apartment housing, it has pointed out that spatial organization of the apartment housing could accommodate residents 'various life style and life cycle. One of such planning methods is a flexible housing. Starting with the Gangbyoun-Siebeom apartment, flexible housing has been developed as merchandising constantly. However, flexible housing doesn't have enough understanding concerning lifestyle or life cycle of user individually, and it also means lack of comprehension and of flexibility, layout from modular coordination and planning of housing component. Therefore, according to the flexibility, the major goal of this research is to analyze the difficulty in realizing further of flexible housing in Korea and suggest implementation and alternatives or directions of flexible housing in Korea.
