This study was conducted to investigate the menu patterns consumed frequently in 5 Korean rural areas for all seasons, using 24-hour recall method with 1,185 subjects. The purpose of this study was to suggest the menu pattern in rural areas for the basis data of the nutrition education program and nutrition intervention project. The result were following : most frequently used menu patterns by the number of side dish were rice + soup + kimchi + 1 side dish> rice + soup + kimchi + 2 side dish> rice + soup + kimchi > rice + stew + kimchi + 1 side dish in the order. Most frequently used menu patterns by the kind of side dish were rice + soup + kimchi > rice + stew + kimch > rice + kimchi> noodle + kimchi in the order. In menu patterns showed higher frequency, Nutrient Adequacy Ratio(NAR) of all nutrients except Ca and Vit A was over 0.7. The Mean Adequacy Ratio (MAR) of rice + soup(or stew) + kimchi + 2(or 3) side dish was 0.76∼0.82. The number of dishes consumed in winter was the highest. The menu had traditional menu pattern based on cooked rice, Korean soup and kimchi in Korean rural areas. With these results, we can conclude that nutrient balances from the menu pattern can be improved, if the composition of main dish and side dish are adequate . For the nutrition program in the community menu patterns should be examined carefully. The result from this study can be used as basic data for nutrition education programs in Korean rural areas.

Purpose: Preventing frequent change and discontinuation of the nurses' carrier is one of major issues for human resource management in a health organization (HO). This study was conducted to get evidences for improvement nursing manpower management and career development of the clinical nurses through investigating affecting factors to their career withdrawal intention (CWI). Methods: A self-report questionnaire survey was conducted on the subjects of the 590 clinical nurses with more than one year tenure from the eight hospitals in Busan city during December, 2013. Data analysis was performed using SPSS program (ver 20.0) and AMOS program (ver 20.0) for structural modeling. Results: Career satisfaction (CS) showed positive(+) effects, and increased with higher job adequacy (${\beta}=.139$, t=2.676, p=.007), job autonomy (${\beta}=.260$, t=4.815, p<.001), and career planning (${\beta}=.301$, t=5.797, p<.001). Career commitment (CC) showed positive(+) effects, and increased with higher job adequacy (${\beta}=.107$, t=2.280, p=.023), job autonomy (${\beta}=.257$, t=5.035, p<.001), career planning (${\beta}=.232$, t=4.717, p<.001), and career satisfaction (CS)(${\beta}=.123$, t=2.293, p=.022). CWI showed negative(-) effects and increased with lower CC (${\beta}=-.906$, t=-15.72, p<.001). Conclusion: Results indicate that CC and CS have important mediating roles between job adequacy, job autonomy, career planning and CWI. As CC directly influenced CWI, there is a need to strengthen CC to prevent frequent changes and discontinuation of nurses' careers and to contribute to productivity HO's.

Background: Several methods have been presented for the evaluation of the endometrium in patients with abnormal uterine bleeding, which include minimal invasive and invasive approaches such as diagnostic curettage or endometrial biopsy by Pipelle. Many studies have been performed in order to compare two methods; diagnostic curettage and outpatient endometrial biopsy. This investigation compared sampling adequacy, endometrial histopathology, failure rates, duration and costs between diagnostic curettage in a hospital and endometrial biopsy. Materials and Methods: This single blind clinical trial was performed on 130 patients older than 35 years who was referred to Amir training hospital in 2013 for elective diagnostic curettage because of abnormal uterine bleeding. For all patients eligible for the study, an endometrial sample by Pipelle was taken without anesthesia or dilatation. Then under general anesthesia diagnostic curettage was performed by sharp curette. Sampling duration was calculated and both samples were sent to the same pathologist. The diagnostic values of two methods in the diagnosis of normal endometrium, endometrial hyperplasia and carcinoma were compared. The costs of these two methods were also compared. Data analysis was performed by SPSS (version 16.0) software. Chi-Square, Fisher, and Pearson tests were used and were considered statistically significant at P values less than 0.05. Results: Two methods were agreed upon 88% of sampling adequacy and 94% of pathological results. Specificity of 100% and sensitivity of 90% for detection of proliferative endometrium, secretory endometrium, simple hyperplasia without atypia and 100% for cancer were recorded. Pipelle diagnostic accuracy in comparison with curettage, have been reported over 97%, so the failure rate in this study was below 5%. Sensitivity of Pipelle for detection of atrophic endometrium was reported below 50%. Duration and cost was lower in Pipelle versus curettage. Conclusions: It is concluded that due to high agreement and cohesion coefficient between curettage and Pipelle on the issue of sampling adequacy, histopathology finding (except atrophic endometrium), low failure rate, duration of sampling and cost, Pipelle can be introduced as a suitable alternative of diagnostic curettage.

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.

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 consumption of a wide variety of food groups is considered one of the key components of nutritional adequacy. The 2005 Dietary Guidelines for Koreans includes the consumption of a variety of foods from diverse food groups as a component of a normal diet. A survey was conducted to evaluate the relationship between the dietary diversity of food groups and nutrient intake in elderly patients (age 65 and above) at a rural area in Korea (Inje). 296 subjects (111 male and 185 female) were probed in a 3 day 24-recall dietary survey. Subjects were grouped according to food group intake frequency, based on six food groups (grain, meat/fish/legume/egg, vegetable, fat/oil, dairy, fruit). Nutritional quality was evaluated according to the numbers of nutrients under EAR (Estimated Average Requirements), and MAR (mean adequacy ratios). The frequency of elderly subjects consuming a meat/fish/legumes/egg food group less than once per day was 29.4%. The frequency of elderly subjects consuming fat/oil food group less than once per day was 65.8%. The percentage of subjects who did not eat dairy food was 88.8%, and that of subjects who did not eat fruit was 57.5%. A stepwise multiple regression analysis was used to develop models relating nutritional quality to possible food group intake frequency factors. Using the number of nutrients under EAR as a dependent variable, the meat/fish/legume/egg food group intake frequency explained 9.9% of variance, followed by the grain group, fat/oil group, dairy group, and vegetable and fruit group (Model $R^2$=0.260). For mean nutrient adequacy ratio as a dependent variable, the model $R^2$ was 0.326. The results of this study suggest that a highly varied diet in elderly might be associated with better nutritional quality, as assessed by nutrient intake. Accordingly, dietary guidelines should take into consideration nutritional characteristics in order to improve intake from all major food groups and to provide a variety of foods in the diet.

Background: New alternative types of pet foods such as raw and cooked homemadestyle diets containing human food ingredients have been introduced due to a trend of pet humanization and diversification of consumer needs. Objectives: To evaluate nutritional adequacy of new alternative types of dog foods containing human food ingredients as maintenance diets for dogs. Methods: Eleven homemade-style foods for adult dogs were purchased from online channel in Korea and analyzed to evaluate nutritional adequacy for adult dogs. Nutrients analyzed included crude protein, amino acids, crude fat, fatty acids, and minerals. Results: Crude protein and amino acids in all products satisfied Association of American Feed Control Officials (AAFCO) requirements. Crude fat in one of 11 products did not meet AAFCO requirements. The most deficient minerals were selenium (10 of 11, 90.9%), copper (five of 11, 45.5%), zinc (five of 11, 45.5%), potassium (three of 11, 27.3%), calcium (three of 11, 27.3%), iron (two of 11, 18.2%), and magnesium (one of 11, 9.1%). Six products were not in the range of the recommended Ca:P ratio in AAFCO dog food maintenance nutrient profiles. Conclusions: This study performed nutritional evaluation of raw and cooked homemadestyle foods as maintenance diets for adult dogs. Some nutritional inadequacies were observed including some minerals, Ca:P ratio, and omega-6:omega-3 fatty acid ratio, although three products (26.2%) satisfied the AAFCO standard except selenium. Overall, the data suggest a need for accurate nutritional adequacy statement for consumers based on proper methods to validate the formula.

Purpose - Why, why is it difficult to predict the appropriateness of self-employment, and what are the countermeasures and policy proposals to overcome. This study intends to further develop the field of statistical variables. It is necessary to overcome the limitation of existing proper scale research in Korea. We need to find statistical variables that can determine the appropriateness of self-employment in Korea. These efforts will be helpful in evaluating OECD countries and statistics and developing domestic economic indicators. Research design, data, and methodology - It is the discovery of statistical indicators and complementary indicators that have not been revealed in previous studies. Therefore, we sought to find new statistical parameters based on the statistics of the Korea National Statistical Office, the Bank of Korea, and overseas OECD statistics. (Proper Size of Adequacy) is defined as the specific gravity or number of the self-employed in Korea, which is shown as "Out Put" by statistical analysis of STATA panel statistical data. It is possible to further develop variables such as gross domestic product, gross national product, economic growth rate, unemployment rate, income tax rate, consumer price, tax level, exports, import amount, bill default I want to dig. Results - In addition to expanding economic indicators that can be explained by self-employment determinants, we have developed a variety of methods such as linear and non-linear (U-shaped, inverted U-shaped). It is the improvement of the self-employment determinants and the analysis method to estimate the appropriate scale. Conclusions - The proposed contents are reflected in self - employment appropriateness evaluation data and hope to help the government to select the policy support and to evaluate the government business after the policy support. These efforts are expected to be of great help to operators operating their own businesses, and to government and related institutional practitioners who support them. In this way, self-employment will be created in accordance with the Korean situation, where the happy life of all the people becomes the premise and the inclusive economic activities are guaranteed. It will improve the method of analyzing proper scale of small business owners and self-employed in Korea.
