  • This study intended to evaluate the validity of the simple nutrition screening test that had been developed with the elderly living in Cheongju as a subject. Nutrition screening score(NSS) and reference standards for nutritional and health status(nutrient intakes, mean adequacy ratio, perceive health, and serum albumin, hematocrit, and hemoglobin) were estimated by using the date obtained in 1996 from the 174 elderly living in Taejon, Statistical analysis showed significant correlations between mean adequacy ratio(MAR) and NSS(r=0.341) and also between NSS and biological indices such as albumin and hematocrit, Around 65-75% of the elderly with perceive health and low level of serum albumin, hemoglobin and hematocrit had NSS$\leq$ll. Sensitivity, specificity, and positive predictive values(PPV) were calculated from the crosstabulation of the three categories of NSS(high, moderate, and low nutritional risk) and low categories MAR(< 0.75, undernutrition;$\geq$0.75, normal) to validate the cut-off point for high or low nutritional risk by NSS. It was suggested that point l1 was appropriate as a criterion to determine high risk of undernutrition, but point 16 was better than 17 as criterion to determine low nutritional risk in the Taejon elderly. When point ll was used as a criterion of high nutritional risk, sensitivity, specificity, and PPV are 59.5, 60.5 and 82.1 respectively. When point 16 was used as a criterion of low nutritional risk, sensitivity, specificity, and PPV are 25.6, 95.4, and 64.7%, respectively. In conclusion, nutrition screening test that had been developed can be a simple, easy, and proper instrument to classify the high risk group of undernutrition. A further validation study seems to be required among other groups of individuals for the screening test to the finalized as a more valid instrument identifying Korean elderly at nutrition and health risk(Korean J Nutrition 33(8) : 864-872, 2000)

  • The performance of projects has always been an area of interest in the construction industry. Roles of all construction supply chain partners are necessary; however the role of a contractor firm in the construction project is pivotal. So, this research intended to explore a Construction Firm's performance criteria which could measure the level of performance of that firm in an ongoing project. Data was collected from construction professionals working in three principal project participant organizations, namely Owner, Consultant and Contractor. A total of 113 nos. of performance measuring items were sorted from literature review and used to collect data. Statistical tools processed by SPSS program was employed to analyze the data. Out of total 113 items, only 65 nos. of variables were found to be acceptable to every population group of this study. Factor analysis revealed 12 key performance predicting factors (KPPF) with 53 predictive indicators. 12 KPPFS with index weight are: work progress and smoothening (9.3%), change order management and work accuracy (9.1%), business relationship building (8.1%), adequacy of construction work procedure (8.6%), quality performance (8.0%), health and site safety adequacy (8.8%), Innovative contractor (8.0%), adequacy of construction site information (6.8%), compliance with contract plan/specification requirements (8.9%), creditworthiness and financial capability (8.3%), intra-agency relationship and responsiveness (7.0%) and resource management (9.2%). These results could be useful to project management body to evaluate performance of its contractor firm on site as well as the contractor itself to assess own performance and its subcontractors on-site.

  • 공간회귀모형은 공간가중행렬을 통해 공간관계를 명시적으로 정량화한다는 점에서 타 모형과 뚜렷하게 구별되는 강점이 있는 동시에, 공간가중행렬 구성에 자의성이 개입된다는 약점을 가지고 있기도 하다. 본 연구에서는 공간가중행렬의 구성에 따라 모형 적합도가 어떻게 변화하는지 인천시를 사례로 실증적으로 검토하였다. 또한 인근지역 범위 설정에 따라 공간시차모형(spatial lag model) 또는 공간오차모형(spatial error model) 중 어떠한 모형이 보다 우수하게 나타는지 검토하였다. 분석 결과, 토지가격 추정에 있어 인근지역 범위를 좁게 파악하는 공간가중행렬을 구성할수록 모형 적합도가 전반적으로 개선되는 것이 확인되었다. 또한, 공간적 이질성이 심한 지역은 공간오차모형의 적합도가 보다 우수한 것으로 파악되었다. 공간적 이질성이 심한 지역은 동질적 성격을 갖는 하부 인근지역으로 세분함으로써 그러한 이질성을 완화시킬 수 있었고, 그 결과 공간오차모형보다 공간시차모형의 적합도가 우수하게 나타날 수 있음을 밝혔다.

  • This study was performed to assess the extent of dietary diversity and nutrient intakes of Korean child-bearing women and to investigate the relationships between dietary diversity indices and nutrient intakes. A total of 91 women aged 18 to 48 years old participated. They were divided into four groups by age 15 subjects in teens, 20 in twenties. 32 in thirties and 24 in forties. Mean energy intake was 1638${\pm}$471㎉/day and it was low as 81.4% of the Korean RDA for energy. Mean intakes of folate, calcium and iron were also low as 81.7%. 72.6% and 57.2% of the RDAs. On the other hand, protein, vitamin A, thiamin, riboflavin and vitamin C were consumed close to or above the RDAs. It was obvious that the subjects in teens and twenties took less all of the nutrients as well as energy than those In thirties and forties. Mean nutrient adequacy ratio( MNAR) was 0.77 and showed a trend to raise with increasing age. Thus MNAR of the teens was the lowest and that of the forties was the highest among the age groups. The results in this study support the previous findings that nutrient intakes of women in teens and twenties were poorer compared to those in thirties and forties. Mean dietary diversity score( DDS) . dietary variety score(DVS) and dietary frequency score( DFS) were 4.1. 11.6 and 14.7. respectively. DVS and DFS of the teens and twenties were lower than those in thirties and forties. DDS significantly correlated to the intakes of energy and calcium only, however, DVS and DFS had significant relationships to the intakes of all nutrients. The MNAR significantly related to DVS and DFS. but not DDS. In conclusion, the intakes of energy, folate. calcium and iron of child-bearing women were not sufficient and their nutrient adequacy highly correlated with dietary diversity. It indicates that to consume various foods helps to enhance the nutritional status.

  • The aim of this study was to provide basic materials that would enable students who take courses in the subjects of technology and home economics to take the knowledge and technological skills they learn in the classroom and apply them to real life situations and to nurture their thinking power and creativity. To achieve these research objectives, a survey was conducted on 217 home economics teachers at 129 schools in the metropolitan area in order to assess their classroom operations and the adequacy of the curriculum regarding "clothes-making and reuse." The results showed that most of the schools surveyed have only one classroom for home economics and that a majority of them are cooking rooms. The most preferred place to practice making clothes was found to be the classroom. In addition, the use of teaching aids pertaining to clothes-making are lacking or in poor shape. Furthermore, analysis of the curriculum regarding "clothes-making and reuse" showed that most of the students use kits that contain materials for making clothes, due to a lack of practice hours. Most teachers thought that this section was appropriate for the school curriculum. In the more detailed categories, the students' ability to use sewing machines was the lowest, while the ability to sew by hand was selected as the most useful and most appropriate for real life situations.

  • The aim to this study was to investigated the effects of family type on the health-related behaviors, food behaviors, and nutrient adequacy ratio of the elderly. Studies were performed on 109 home-bound elderly in a rural area of Asan city, in 1996. Subjects were divided into two groups by their family type, one was single-elderly family(n=58) and the other was extended family(n=51). The results obtained by questionaires and personal interviews as follows. 1) The average age 68.6. They served in primary industry, and 89.1% of responders received less than a primary school education. There was no significant difference by family type. 2) Single-elderly family members themselves felt more negative about their health than extended family members. 3)Each nutrient adequacy ratio of single-elderly family/extended family members was 0.72/0.76 of energy, 0.73/0.76 of protein, 0.59/0.66 of Ca, 0.98/0.99 of Fe, 0.62/0.74 of vitamin A, 0.86/0.87 of thiamin, 0.72/0.73 of riboflavin, 0.71/0.77 of niacin, 0.90/0.91 of ascorbic acid, and 0.76/0.80 of Mar. The NAR of vitamin A of the single-elderly family members was significantly lower than for extended family members(p〈0.05). Energy, protein, Ca, vitamin A, riboflavin showed insufficient intake for both groups. The percentage of INQ〈1 of the single-elderly family/extended family members was 45.6/51.0 of protein, 66.7/66.7 of Ca, 64.9/56.9 of vitamin A. By NAR and INQ, the most insufficient nutrient to the elderly in this rural area was Ca. We there for suggest that it is needed for elderly in rural areas to receive of food that is higher ING of Ca.

  • A deep understanding of the dietary patterns and nutrient intake is important for assessment of possilbe nutritional risk and for establishing nutrition improvement strategies. This study was conducted toexamine the dietary characteristics of a nutritionally poor elderly group compared to the middle-and highly-nourished group. Elderly participant was recruited from local elderly centers in Suwon city in 1998. Trained dietitians interviewed 119 elderly(35 males, 84 females) aged 60 years and over for collecting dietary data(24-hour recall) and related variables. Male and female subjects were grouped into high, middle, and low according to the mean nutrient adequancy ratio(MAR) tertiles. An analysisof the percentage of RDA(Recommended Daily Allowances of Korea) for each of the 10 nutrients showed that the male low-MAR group consumed below the RDA in all kinds of nutrients, and the female low-MAR group consumed nutrients below the RDA except vitamin C. An evaluation of nutrient density by Index of Nutritonal Quality(INQ) also showed a similar tendency. Thus, the INQ level of the male low-MAR group was significantly lower than the middle-or high-MAR group, especially in protein, vitamin A, thiamin, riboflavin, and phosphorus(p<0.05). Moreover, INQ level of female low-MAR group was significantly lower than that of the high group(p<0.05) in all nutrients. The female low-MAR group's daily food intake were also lower than those of the high-MARgroup in gains, fish, fruits, oil and beverages. The energy distribution from carbohydrates, fats and proteins showed that the male low-MAR group had significantly higher carbohydrate and lower fat proportions compared to each gender high-MAR group, respectively. The male and female low-MAR group had low scores about eating all side dishes. These findings indicate that a moderate increase of the meat/egg/fishes intake was needed by the male low-MAR group for improving nutrition adequacy, and an overall increase of the food quantity and quality was desired for the female low-MAR group. These data could be used for planning a community elderly nutrition program and establishing strategies for tailored guidelines for the individuals.

  • 사회보장제도에 대한 정책평가의 핵심은 그것이 국민들을 사회적 위험으로부터 얼마나 효과적으로 보호하고 있는지를 살펴보는 데 있다. 본 논문은 <한국복지패널>자료를 이용하여 현재 시행중인 5개 주요 소득보장제도가 빈곤의 위험에 대처하는 데 얼마나 효과가 있는지를 포괄성과 충분성에 주목하여 분석하였다. 이때 각 제도별로는 물론 5개 제도 묶음이 나타내는 효과에 대해서 살펴보았고, 그 효과를 세분화된 집단별로 비교하였다. 그 결과 빈곤층 가운데 약 35%가 소득보장제도의 혜택을 전혀 받지 못하는 것으로 나타났다. 노인층에 대한 소득보장제도의 포괄성과 충분성은 상대적으로 높았으나 비노인층, 특히 실업자에 대한 포괄성과 충분성이 매우 낮게 나타났다. 이러한 점들은 한국의 소득보장제도가 여전히 많은 개선의 여지를 남겨두고 있다는 점, 특히 근로연령층 대상 소득보장제도의 개선과 확충이 필요하다는 사실을 시사한다.

  • The grouping analysis is a method guided by the Korea Radioactive Waste Agency for efficient analysis of radioactive waste for disposal. In this study, experiments to verify the adequacy of grouping analysis were conducted with radioactive soil, concrete, and dry active waste in similar environments. First, analysis results of the major radionuclide concentrations in individual waste samples were reviewed to evaluate whether wastes from similar environments correspond to a single waste stream. As a result, the soil and concrete waste were identified as a single waste stream because the distribution range of radionuclide concentrations was "within a factor of 10", the range that meet the criterion of the U.S. Nuclear Regulatory Commission for a single waste stream. On the other hand, the dry active waste was judged to correspond to distinct waste streams. Second, after analyzing the composite samples prepared by grouping the individual samples, the population means of the values of "composite sample analysis results/individual sample analysis results" were estimated at a 95% confidence level. The results showed that all evaluation values for soil and concrete waste were within the set reference values (0.1-10) when five-package and ten-package grouping analyses were conducted, verifying the adequacy of the grouping analysis.
