  • 해외 플랜트 사업에서의 고부가가치를 창출하기 위해서는 기획 타당성조사, 프로젝트종합관리, FEED 및 기본설계 등 분야의 기술경쟁력 강화가 시급하다. 특히, FEED 업무는 프로젝트 전체에 대한 영향력이 절대적이고, 또한 기자재 및 패키지 산업의 경쟁력 강화에도 결정적 역할을 한다. 그럼에도 불구하고, FEED 관련 선행연구들은 설계업무 중심의 프로세스 및 성과물을 위한 연구가 대부분이며, 프로젝트 전체에 영향을 미치는 관리적 관점의 FEED 업무에 대한 연구는 미흡한 실정이다. 따라서 본 연구에서는 발전플랜트 중 화력발전소를 대상으로 사업관리 관점의 FEED 업무 프로세스 구조 및 항목을 제안하였다. 도출된 FEED 관리 업무는 3개의 레벨로 나누어진 계층적 구조를 가지고 있으며, 업무 항목에 대한 전문가 검증을 실시하였다. 또한 FEED 관리 업무에 대한 평가지표별 평가를 통해 결과를 분석한 결과 설계 중심의 업무들은 역량이 높지만 중요도가 높은 관리적 관점의 FEED 업무들의 역량은 부족한 것으로 나타났다. 그러므로 본 연구에서 제안한 FEED 관리업무 프로세스 구조는 FEED 역량 강화를 위한 가이드라인이 될 것이라 기대한다.

  • Human being does work to live out and they have their private life because human has sociality. Both work and life are important to live out but they are on the trade-off relationship. Because keeping the balance between work and life is too hard, it has been interested by academic and practical areas. Definition of Work-life balance here is that balance or imbalance arising between work and life has no negative impact on their daily life. Above all, Work-life balance is important because it is strongly related to identity. Recently, the introduction of the mobile office system has emerged as a way to solve the problem of work-life balance. It is based on the teleworking which was formerly generated. Teleworking is to perform the work in the employee's home or office space set aside without going into the workplace. Concept of the mobile office system here is not only using portable devices during work for convenience but also the system which is designed for the performance. Thanks to the diffusion of smart devices(smart phone, tablet pc), mobile office system has been spread. Although the importance of mobile office systems is emerging, there are few researches about it. Even they mostly focus on the standpoint of performance of mobile office system. However, Quality of life is as important as the performance. As a part of Quality of Life field, Work-life balance is the closest to employee's quality of life. So this study aims to examine the effect of the use of mobile office systems on work-life balance. To do so, we try to find factors effecting Work-life balance from existing studies and then set a research model. We set the use of mobile office systems as independent variables which are divided by use of function, use by location and use by situation. There are four dependent variables - sense of self command, sense of balance, solving work problem, solving life problem. We collected data from employees who are using mobile office systems on their job. 215 people were participated in the survey and we used multiple regression analysis to verify our research model. Results show that every independent variable has no impact on solving work problem while they have slight impact on the other dependent variables. Especially use on the business trip has significant effect on dependent variables. It means that there is a possibility use of mobile office system could control the employee's quality of life and system should be evolved until it covers even critical tasks. Also, support for mobile office system -education, encouragement-should be provided. By mobile office system is maturing, future research would be done.

  • Fundamental direction of the seventh education curriculum aims to nurture active and creative Koreans for globalized and information-oriented society of 21 century, and emphasizes the importance of career education identifying its subsections that are practices of student-focused education of aptitude, ability and career. Hence, as a clear targeting of career objective from elementary school through relevant career education enables them to recognize appropriate career for themselves, the basis of self- actualization and social contribution must be settled. This paper seeks to identify the relationship between career awareness and self-esteem by examining and analysing differences of sex, region and level. This study selected 536 samples from 4th and 6th year elementary school students in C city and S town of Chungcheong province. Career awareness test and self-esteem test is used as a measurement, statistical process control (SPC) of career awareness and self-esteem (M, SD, r) is made for each variable, and the significance was tested. The result of this research can be summarized as follows: First, generally there is very significant regional differences of career awareness (F=16.817, p<.001), which contains that urban children has higher career awareness (M=120.22) than that of rural children (M=113.87). In subsections of career awareness, self-esteem of urban children is higher than that of rural children, and the attitude & for career and values of girls is higher than that of boys. In terms of the career planning, urban children and 6th year students are higher than rural children and 4th year students. Second, self-esteem generally has very significant regional difference (F=12.123, p<.01), which contains that the self-esteem of urban children (M=106.50) is higher than that of rural children (M=101.80). In comparison of different forms, a very significant difference is as much as p<.01 level (F=11.046), which contains 4th year students (M=105.63) have higher self-esteem than 6th year students (M=102.05). In subsections of self-esteem, gross self-esteem and social self-esteem of urban children are higher than rural children. In terms of family self-esteem, urban children and 4th year students have higher figure than rural children and 6th year students. In school self-esteem, 4th year students had higher level than the 6th. Third, the career awareness and self-esteem are generally related as r= .50, it was very significant at p<. 001 level. All subsections of career awareness had positive relationships except the school self-esteem. According to the result, rural children had relatively low career awareness and self-esteem. This is presumably due to relatively poor circumstances for rural children, comparing to that of urban children. Therefore rural elementary schools should try to let them have appropriate career awareness by associating with family, school and local society to expand the opportunity of experiences for the self perception of aptitude, nature and interest. In addition, we have to strive for the whole-minded education increasing the self-esteem of rural children and giving them positive thinking through career counselling, personal counselling and group counselling.

  • 연평균 일교통량(AADT)은 교통 및 도로부문에서 중요한 기초자료로 활용되지만 예산 제약 등의 한계로 인해 일부 지점에 대해서만 상시조사를 통해서 AADT를 산출하고 있으며, 대다수의 지점에서는 단기 교통량 조사에서 수집된 샘플자료를 이용하여 AADT를 추정 활용하고 있다. 현재 단기 교통량 조사지점의 AADT 추정을 위하여 조사된 자료를 단순 평균하는 방법이 적용되고 있다. 기존 AADT 추정모형은 보정계수를 적용하는 방법이 대표적인 방법이나, 이 방법은 단기 교통량 조사 지점이 어떤 상시조사 지점의 보정계수를 적용할지에 대한 객관적인 방법이 없어 한계가 있다. 이에 본 연구에서는 공간통계모형을 도입하여 교통량 자료의 공간상관관계를 분석하고, 크리깅 모형을 적용하여 AADT를 추정하는 방법에 대하여 알아보았다. 공간통계모형의 AADT 추정의 정확도를 기존 연구와 비교하기 위하여 동일 대구간의 상시조사 지점의 보정계수를 적용하는 방법(방법 1)과 보정계수 그룹핑을 이용하여 해당 그룹의 보정계수를 적용하는 방법(방법 2), 공동크리깅을 적용한 방법(방법 3)을 비교분석하였다. 분석결과 공동크리깅을 적용한 모형은 기존 모형에 비해 AADT 추정 정확도가 향상되는 것으로 나타났다.

  • Present study was attempt to explore the relationship between perceived family support and depression and to emphasize the importance or needs of family support in psychological care especially among adolescents. Study subjects comprized of 308 high school students including vocational students in part, and data collection was done in the Kwangju City area in April. 1998. The Moos Family Environment Scale and the Zung's Self-Rating Depression Scale modified by investigators were used as measurement tools of 59 item questionnaire and in data analysis, statistical methods of T-test, ANOVA. and Pearson Correlation Coefficient were utilized. The study findings are as follows 1. The hypothesis of the study, 'the higher the degree of perceived family support among adolescents, the lower the level of depression', was supported (r=-0.4469, p<.001). 2. Some variables in demographic characteristics related to the degree of family support with statistical significance were school division of vacational vs non-vocational(t=-2.02, p<.05), age(f=5.47, p<.01), family monthly income (f=2.49, p<.05), mother's level of education (f=3.01. p<.05), residence at developmental stage (f=2.87, p<.05), personal problem of highest priority at present(f=7.73, p<.001), and family problem perceived by adolescents(f=7.38, p< .001). 3. Items In general characteristics related to the level of depression with statistical significance were sex(t=-2.91, p<.0l). mother's level of education(f=2.53. p<.05). residence at developmental stage (f=3.95. p<.0l). present personal problem of highest priority (f=3.68. p<.1l). and perceived in-family problem (f=4.58. p<.001). 4. The mean score of the degree of perceived family support was 61.26 $(SD=\pm14.45)$ in a range of 21.00 to 96.00 ; that of the level of depression. 43.74 $(SD=\pm8.04)$ in a range of 23.00 to 67.00. which demonstrated that the higher the degree of perceived family support, the lower the level of depression. In conclusion. it was found that the degree of family support perceived by adolescents is a variable affecting the level of depression. Based on the study outcome, further research suggestions can be made as such that repeated studies are needed in order to delineate the various factors affecting family support and depression, and a study involving family support implementation program is required as a nursing intervention for the development of emotional security among adolescents, perceived family support, depression, adolescence.

  • Purpose: The purpose of this study was to identify differences of BMI, pain, depression, self-esteem and self-efficacy between rheumatoid arthritis and osteoarthritis patients. Method: The study subjects were 135 persons having chronic arthritis at rheumatology clinic and the department of orthopedic surgery of the C university hospital in D city. The data were collected from February 19th to April 7th, 2003. The data analysis consisted of $X^{2}-test$, t-test, Pearson Correlation Coefficient, and multiple regression using SPSSWIN 10.0 program. Result: 1. There were significant differences in age(p=0.000), occupation(p=0.015), marriage(p=0.028), duration of illness(p=0.000), BMI(p=0.006) and Self-efficacy(p=0.017) between rheumatoid arthritis and osteoarthritis patients. 2. In rheumatoid arthritis, the BMI and self-esteem(r=-0.239, p=0.05) were significantly correlated and also pain and self-esteem(r=-0.402, p=0.01), pain and self-efficacy(r=-0.455, p=0.01) were significantly negatively correlated. The self-esteem and depression(r=-0.622, p=0.01), self-efficacy and depression(r=-0.729, p=0.01) were significantly negatively correlated and also pain and depression(r=0.432, p=0.01), self-esteem and self-efficacy(r=-0.476, p=0.01) were significantly positively correlated. In osteoarthritis, the pain and self-esteem(r=-0.225, p=0.01) were significantly negatively correlated and also pain and self-efficacy(r=-0.493, p=0.01), self-esteem and depression(r=-0.692, p=0.01), self-efficacy and depression(r=-0.566, p=0.01) were significantly negatively correlated. The pain and depression(r=0.290, p=0.05), self-esteem and self-efficacy(r=0.383, p=0.01) were significantly positively correlated. 3. The factors influenced by the self-efficacy, the depression and age in rheumatoid arthritis explained 56.2%, the depression and pain in osteoarthritis explained 43.9%. The factors influenced by the BMI, the self-esteem in rheumatoid arthritis explained 5.7%, but there was no significantly variable in osteoarthritis. Conclusion: The results support the importance of different nursing intervention focused on BMI and self-efficacy in patients with rheumatoid arthritis and osteoarthritis. There is a need for further studies to identify relation of variables in different diseases related to arthritis.
