본 연구에서는 군수품 무역대리점과 관련하여 크게 두가지의 연구를 수행하였다. 첫째는 군수품 무역대리점의 활용 효과도를 정량적으로 측정하기 위해 방위사업 종사자들을 대상으로 설문조사를 하였고, 두 번째는 중개수수료의 적정 기준을 제시하기 위해 실제 무기체계 국외구매사업의 사례에서 군수품 무역대리점이 실제로 활동한 내역을 분석함과 동시에 통계청에서 발표한 일반 상품중계업의 평균 영업이익이 군수품 중개업에도 보장될 수 있도록 적용하였다. 그 결과 군수품 무역대리점의 효과도 측면의 설문조사에서는 무역대리점을 활용하는 것이 활용하지 않는 것 대비 1.07배 효과적인 것으로 분석되었다. 적정 중개수수료와 관련된 분석에서는 중/소형사업과 대형 사업에서 상이한 결과가 나왔는데, 중/소형사업의 경우 총사업비의 5.1~8.7%가 적정 중개수수료인 반면, 대형사업의 경우 총사업비의 1.2~1.8%가 적정 중개수수료로 분석되었다. 따라서 본 연구에서는 군수품 무역대리점을 활용시 활용하지 않는 것 대비 어느 정도 효용성이 있는 것으로 확인되었고, 만약 정부가 적정 중개수수료율을 제시한다면 지금까지 논의 되었던 것처럼 고정된 특정 값을 일괄적으로 제시하는 것은 현실적이지 않고 총사업비 규모에 따라서 그 요율을 탄력적으로 적용하되, 사업의 성격을 분석하여 필수 활동비 소요를 사전에 파악하여 가감하는 것이 적절함을 알 수 있었다.

Experiment study on a down scaled two-phase catalytic reactor is presented. As a preliminary step for the development of catalytic reactor, nano-particulate catalyst was prepared. Perovskite La$\_$0.8/Sr$\_$0.2/CoO$_3$is chosen and synthesized as a catalyst considering superior catalytic performance in reduction and oxidation process where oxygen is involved among the reagent. Reactor that has a scale of 2${\times}$10${\times}$25mm was made by machining of A1 block as a layered structure considering further extension to micro-machining. Hydrogen peroxide of 70wt% was adopted as reactant and was provided to the reactor loaded with 1.5 g of catalyst. Reactant flow rate was varied by precision pump with a range of 0.15cc/min to 17.2cc/min. Temperature distribution within reactor was recorded by 3 thermocouples and total amount of liquid product was measured. Temperature distribution and factors that affect temperature were observed and relation between temperature distribution and production rate was also analyzed. Relative time scale plays a significant role in the performance of the reactor. To obtain steady state operation, appropriate ratio of flow rate, catalyst mass and reactor geometry is required and furthermore to get more efficient production rate temperature distribution should be evenly distributed. The database obtained by the experiment will be used as a design parameter for micro reactor.

The purpose of this study was to examine the feasibility of standardizing the Bayley Scales of Infant Development(BSID) for Korean infants. To examine whether the Korean version of BSID is appropriate for Korean infants during the first 30 months of age, the Scale was administered to 285 Korean infants in 14 age groups. The infants were from intact and mostly middle-class families. According to item rewponse analyses of the Mental and the Motor Scales, the passing rate on each item increased by the infant's age. Regularity rather than irregularity was found on most items. Ordinarily of the Mental and the Motor Scale items in terns of age placement was similar to that of the U. S. sample. Several items, however, could be rearranged based on the data from the Korean sample. The total scores of the Mental and the Motor Scales reflected developmental trends in which score differences with a conjoining age group ranged from 3 to 15 for the Mental Scale, and 2 to 10 for the Motor Scale. Correlations between the two Scales in each age group were low to moderate (.03 to .67), with a median of .34. Reliabilities of the Korean version of the BSID in terms of the split-half reliability coefficients and the tester-observer agreements were satisfactory. Similarities as well as differences were found in developmental trends of infants between two cultures. A further study is needed not only to confirm results of this study but to set forth the standardization of the Bayley Scales to Korean infants.

Factors related to health promotion activities and quality of life in Korean women with arthritis have not been clearly identified. Predictors of health promotion might be identified that will enhance the well - being of this group. Accordingly, the findings of the study will contribute additional information about the relationship between health promotion and quality of life and will add to the research on quality of life of individuals with a leading cause of disability--arthritis. The purpose of the study was to examine the relationship of selected background factors (years of illness, perceived severity of illness, uncertainty in illness), perceived self- efficacy, and health promoting behaviors to the quality of life of Korean women with arthritis. A cross - sectional descriptive design was used in this study to investigate relationships among the variables of interest. The sample was composed of 96 women who had arhtrits and visited large university hospital in Seoul for regular check up or pre-scription of medication. The purpose of a descriptive correlational design was to determine the absence or presence of relationships among variables that were measurable (Polit & Hungler, 1981, p.147). The design of this study was appropriate because it yielded answers to the research questions and hypotheses regarding the relationships among the model variables. the Questionnaire contained demographic information, translated Mishel Uncertainty in illness Scale-Community form (MUIS-C) (Mishel, 1987), translated and modified Disease Course Graphic Scale(DCGS) which was developed by Braden (1990), translated Sherer. et al.’s General Self-Efficacy Scale (1982), The Health -Promoting Lifestyle Profile (HPLP), developed by Walker, Sechrist, and Fender (1987) and traslated to Korean by Ha, and quality of life was measured by Face Scale (Andrew, 1976). Several steps of verification for the translation process were carefully conducted. Data analysis included descriptive correlational statistics and multiple regression techniques. Health promotion was the only contributor to pre-dict quality of life. Results showed that enabling cognitive perceptual factor (self-efficacy) mediates the disruptive force (uncertainty in ill-ness) on achieving a health promoting self- help behavior. The findings of this study also indicated that illness - related variable of severity of illness was mediated by health promotion, which buffered it's impact on quality of life.

The purpose of this study was to examine if Likert scales had been properly utilized in community nutrition research. A total of 527 research articles published in the 32 issues of Korean Journal of Community Nutrition from the volume 5, issue 1 in 2000 to the volume 10, issue 2 in 2005 were screened and 55 articles were found to have utilized one or more Likert scales for the studies. Therefore, 109 Likert scales used in the 55 studies were reviewed regarding the name, statement and response items, reliability and validity check, and analysis method. The scales were mostly referred as Likert scales (60%) or Likert-type scales (27%). Some scales were found to be referred as Likert scales although they were Likert-type scales when judged based on the information given in the respective articles. However some scales couldn't be judged for the rightness of the names because the information given for the scales in the articles was not enough. About 23% of the scales consisted of items less than 6 or more than 30, and therefore found to be inappropriate. The percentage of the scales listing all the statement items in the articles was only 25%. Most of the scales (85%) included 5 response items, and the rest included 4 (7%), 7 (6%), or 3 (2%). The percentages of the scales including appropriate center and end items were only 2% and 22%, respectively. Less than half of the scales (41%) were found to have been checked for reliability and only one scale was reported to have been checked for validity. In some scales (6%), the responses were scored improperly for analysis. The responses to the scales were frequently found to have been analyzed by parametric statistics such as mean, ANOVA, t-test, and Pearson's correlation, which might be a problem depending on the size and distribution of study samples. In conclusion, there is much room for improvement in the use of Likert scales in community nutrition research.
