This study investigated the nutrition education realities and nutrition status of children in community child centers, by analyzing the status of nutrition education, nutrition quotient (NQ), and the level of maintaining dietary guidelines. The subjects were 173 children from grades 1 to 6, enrolled in community child centers, Jinju, Kyungnam. The NQ was examined by a questionnaire, which was a checklist of 19 food behavior items. The distribution of scores (out of 100) in the nutrition quotient were as follows: total score of NQ was 59.4, balance 56.6, diversity 60.6, moderation 65.6, regularity 60.9, and practice 56.7. Nutrition quotient was higher in the higher graders due to significant differences in the area of variety. The level of maintaining dietary guidelines was higher in girls, especially in the area 'eat politely with family', and higher amongst the upper graders in the area 'have safe snack wisely'. To improve the eating habits and nutritional status of the children in community child centers, their nutritional state should be checked with regular and systematic education, and their nutritional management should be pursued continuously. Since the assessment of the eating behaviors and the nutritional state of children is important at home as well as in schools and community child centers, nutritional education should be further extended to the parents and their care givers. This study can be implemented as basic material for the nutritional education of children, to minimize the dangers of malnutrition and to help build up the right eating habits amongst children in community child centers.

This paper aims to find out the current state of early English education in the world(including Korea) and to suggest its more desirable direction, with special reference to TEFL in elementary schools of Korea. In fact English teaching in elementary schools of Korea has been put into practice as an extracurricular activity since 1982. But in 1995 the Ministry of Education proclaimed a policy to establish a TEFL program as the regular course in elementary schools of Korea since 1997. In this connection, the writer surveyed several kinds of theories about early English education to verify the necessity and validity of Korea's elementary school English education. The logical result from these theories is that younger children are better equipped to learn foreign languages with efficiency than older children or adults. However, as most studies are based on logical inferences rather than on direct observation or experimental evidence, we are not sure that those theories are right. In this view, the writer put stress on the preparation of educational environments to establish a more desirable direction of early English education in Korea, since Korea's elementary school English education will be practiced under EFL environment, not ESL environment. The writer also pointed out some problems of educational finances, the curriculum development process and its content, teaching materials(textbooks and tapes), English teachers, teaching methods, evaluation, educational facilities. This paper concludes that we have to try to solve these problems to succeed in a TEFL program in elementary schools of Korea and suggests several things for a more desirable direction of Korea's elementary school English education.

Objectives : Basic life support (BLS) is considered one of the essential clinical skills medical students should master. Nevertheless, neither the current state of education nor the educative effect of and attitudes toward BLS in Korean medical students have yet been reported. The aim of this study was to examine the educative effect of BLS training for Korean medical students in terms of attitudes, knowledge, and skills. Methods : Surveys concerning attitudes toward BLS and its education, and tests for knowledge and scheme performance were conducted with 85 students in a college of Korean medicine under training for American Heart Association (AHA) BLS course for healthcare providers. Results : Before training, 70.6% of students answered they felt the necessity to be trained in the BLS course. The levels of confidence to perform and self-presumed knowledge on BLS were low at first. After training, however, the level of confidence and knowledge increased significantly. In the final test, the mean scores of written test and scheme performance significantly decreased, while the level of confidence didn't. Most of the participants answered they wanted to be re-trained under regular re-education system. Conclusions : To evaluate the current state of BLS education and its educative effect in Korean medical schools, it's required to expand the target of research to larger number of colleges and students over the country.

Three inspection-ordering policies of a part with three types of lead times, i. e., expedited lead time, special lead time and regular lead time are considered. Policy I : The original part is replaced by a spare immediately after delivery, even if the original part is still operating. Policy II : The delivered spare is put into inventory until the original part failes. Policy III : The original part is inspected once again immediately after the delivery of the spare. If it is in a good state, the original part is used up to its mean degradation time, then replaced. If it is in a degradation state, the original part is replaced by a spare. A cost effectiveness for each policy is analyzed. Optimal inspection-ordering policy which maximizes a cost effectiveness is obtained. Time to degradation distribution and time to failure distribution are assumed to be Weibull and exponential, respectively. Variations of policies are observed with respect to variations of associated costs.

Background: Colon polyps need to be excised upon detection during colonoscopy due to the risk of malignancy irrespective of their size. In our study, we retrospectively evaluated the clinicopathological characteristics of polyps detected during colonoscopy. Materials and Methods: We assessed 379 patients with polyps detected during colonoscopy between January 2010 and May 2012. The demographics, complaints, colonoscopy findings (shape, place and size of the polyp) and histopathological findings were recorded. We carried out statistical analysis using PASW 18.0 for Windows. Results: There were 227 males (59.9%) and 152 females (40.1%) in the trial. The mean age was 53.8 years (32-90). The most common complaint was rectal bleeding (36.1%), followed by abdominal pain (35.4%). Polyps were detected most commonly in the rectosigmoid region (43.8%), followed by the descending colon (17.4%). Some 239 patients had a single polyp (63.1%) while 140 were found to have multiple polyps (36.9%). While tubular adenoma was the most common pathological type, occurring in 181 patients (47.8%), tubulovillous adenoma (14.2%) and hyperplastic polyp (12.7%) followed, occurring in 54 and 48 patients respectively. While 313 patients (82.6%) did not feature dysplasia, 37 patients (9.7%) exhibited low-grade dysplasia, 28 (7.7%) had high-grade dysplasia and 4 had cancer (1.1%). The rates of villous components and dysplasia were detected to be high among pedunculated polyps and polyps larger than 1 cm (p<0.001). Conclusions: Due to the fact that large-diameter polyps with malignant potential are commonly located in the left colon and have a high prevalence among the middle-aged individuals, it would be appropriate to screen this population at regular intervals via rectosigmoidoscopy.

Purpose: To appraise the frequency of cervical cytological abnormalities in a population at normal risk via analysing the archive records of cytology for the period of approximately 9,5 years, comparing them with patient demographic charecteristics, and discuss the results for women under age of 35. Materials and Methods: A total of 32,578 cases of Pap smears were retrieved and analysed from our archive included the Pap tests performed between January 2001 and April 2010 at the Early Cancer Screening, Diagnosing and Education Center by the consent of three pathologists via utilizing the Bethesda System Criteria 2001 and the results were compared with some demographical characteristics. Results: Our rate of the cervical cytological abnormality was 1.83%, with ASCUS in 1.18%, LSIL in 0.39, HSIL in 0.16%, AGUS in 0.07%, squamous cell carcinoma in 0.02%, and adenoarcinoma in 0.006%. Cytological abnormalities were detected mostly in those with higher age, lower parity, and premenopausal period whereas the smoking status was without influence. Bacterial vaginosis (5.6%) was the most frequent infectious finding (Candida albicans 2.7%; Actinomyces sp. 1.3%; and Trichomonas vaginalis 0.2%) detected on the smears. The rate of abnormal cervical cytology was 9.5% among the women aged between 30-34. Conclusions: Early detection of the cervical abnormalities by means of the regular cervical cancer screening programmes is useful to attenuate the incidence, mortality, and morbidity of cervical cancer. Our prevalence of the cytological abnormalities was much lower than the one in Western populations in general but very similar to those reported from other Islamic countries that may be explained by the conservative lifestyle and the lower prevalence of HPV in Turkey. A remarkable rate of abnormal cervical cytology of women aged 30-34 was pointed out in the present study.

Differences in dietary intake of Korean Americans (KA) by the length of residence in the U.S. were studied in relation to health and disease patterns in Michigan. Of 1860 questionnaires mailed, 637 (34.3%) responded with demographics, anthropometrics, self-reported disease patterns, lifestyle, and dietary patterns (93-item FFQ developed for KA). Complete responses were available for 498 people (263 men,253 women, aged 30-87 yr), who were then divided into three groups based on the number of years lived in the U.S.: 15y, 16-25y, 26y. Age-adjusted weight, height, BMI, and waist to hip ratio were within the normal ranges and did not differ among the three groups. Chronic diseases frequently reported in men and women (age-adjusted) included hypertension (14.4%, 14.1%), digestive diseases (5.4%, 8.5%), diabetes (3.6%,4.9%), and arthritis(3.3%, 12.5%), respectively. The length of residence in the U.S. was inversely associated with the age-adjusted prevalence of digestive diseases (12.4%, 6.5%, 0.4% in men, 13.0%, 11.7%, 0% in women). The length of residence was positively associated with health consciousness, receiving regular health care, taking supplements regularly, and exercising, while inversely related to smoking. The majority favored American foods for breakfast and Korean foods for dinner. Foods frequently consumed included cooked rice (w/other grains). kimchi, coffee (w/cream and sugar),bread (white and dark), citrus juice, milk (low fat and skim), lettuce and cucumber, apple, seaweed, and soda. Intake frequency of the Korean starch food group was inversely associated with the length of residence for both men and women (p<0.001), but not with the American starch food group. Fat intake did not differ by the length of residence in the U.S. The dietary changes were associated with the length of residence and chronic disease patterns for the first generation of KA, which should be further examined 'for the subsequent generation of KA.

In present study, a two dimensional unsteady Navier-Stokes solver has been developed using the Diagonalized ADI (DADI) method and implicit dual time stepping method. The jacobian matrices in steady state Navier-Stokes equations are introduced from inviscid flux terms. The implicit treatment of artificial dissipation terms results in a block penta-diagonal matrix system and it becomes a scalar penta-diagonal matrix by diagonalization. In steady state equations about fictitious time, a new residual including a real time derivative term is introduced. From a converged solution about fictitious time, a real time unsteady solution can be obtained, which is called 'implicit dual time stepping method'. For code validation, an oscillating flat plate, a regular Karman vortices past a circular cylinder and shock buffeting around a bicircular airfoil problems are numerically solved. And they are compared with a theoretical solution, experiments and other researcher's computations.

Museum Records is both a resource for the administration and for researchers. And It is necessary for the day-to-day operation of the museum's activity and it serves researchers of all kinds. This study is aimed to grasp the present condition of museum records management in a National Museum of Korea and 11 local national museums in Korea as a case study. To this end, two methods were used to collect the essential data. First, a comprehensive literature survey was conducted to investigate foreign successful museum records management system. Second, interview and questionnaire survey were conducted to collect the data of actual state of National Museum. The results show that National Museum should be a wholly responsible for the department and disposition of professional staffs and set up the comprehensive registration system, the standard of classification considering the museum's feature and the regular estimation system. And also National Museum should expand and improve the facilities according to "Archives and Records Management of Public Agencies Act".
