Purpose: This study was performed to investigate the correlation between mother's characteristics and obesity index, percentage of body fat, total cholesterol, and serum leptin levels in obese children. Method: Sixty two students in 4th, 5th, and 6th grades were selected from two elementary schools located in the suburbs of Seoul. Mother's characteristics were collected by questionnaires. Biophysical indexes were as follows; obesity indexes were calculated by height and weight, percentages of body fat were measured by a bioelectrical impedence fatness analyzer, total cholesterol levels were measured by a Hitachi automatic analyzer, and serum leptin levels were measured by the immunoradiometric assay method. Result: The degree of mother's concern for their children's obesity showed a statistically significant positive correlation with biophysical indexes such as obesity index and serum leptin level in obese children. However, there were no significant correlations between mother's economic state, education level, occupation and biophysical indexes. Also, there were no significant correlations between mother's concern for their children's obesity and percentage of body fat, and serum cholesterol levels. Conclusion: These results indicate that mother's concern for their children's obesity is one of the most important factors in child obesity.

Chilsan-do Island, South Korea, has previously been identified as one of the biggest spawning sites of the small yellow croaker Larimichthys polyactis in the Yellow Sea. To determine whether Chilsan-do still serves as a spawning site for L. polyactis, three to five stations around Chilsan-do Island were surveyed for eggs from April to June (the main spawning season of L. polyactis) in 2019, using an RN80 net. For the first time, three L. polyactis eggs were identified at two stations, located just in front of Chilsan-do Island and between Chilsan-do and the coastline, only in May. The diameter of L. polyactis eggs (1.26-1.34 mm) was very similar to those of Collichthys niveatus (1.30-1.37 mm) and Setipinna tenuifilis (1.34-1.35 mm). During the survey period, the sea surface salinity remained constant (32.0-32.1 psu), but the sea surface temperature (SST) rapidly rose from 13.6-13.7℃ in April to 22.1℃ in May. Our findings suggest that L. polyactis still spawns near Chilsan-do Island today, but on a very small scale, and that changes in SST promote spawning of L. polyactis.

Purpose: This study was to test the effectiveness of Web-based multimedia contents for Physical Examination and Health Assessment on learning achievement. Method: Multimedia contents based on Jung's teaching and learning structure model were used to enhance learning achievement. Learning achievement was measured by the knowledge of Physical Examination and Health Assessment. The participants of this study were students in a BSN and RN-BSN program in a university located in Seoul. 59 students in the experimental group received lectures using web-based multimedia contents and 75 students in the control group received regular lectures. Results: The mean score of the degree of educational achievement in the experimental group(mean=31.09) was significantly higher than in the control group(mean=25.55)(t=-3.883, p=.000). Conclusion: These web-based multimedia contents were found to maximizethe effectiveness of the teaching process when used as a teaching aid, and yet kept the strength of a face to face teaching learning method. This program is recommended as part of a main text, vital teaching aid or cyber lecture materials in nursing schools and in health care educational institutions.

N-Alkyl/benzyl substituted isatin derivatives are intermediates and synthetic precursors for the preparation of biological active heterocycles. N-alkyl/benzyl isatins have showed various biological activities, such as cytotoxicity, antiviral, caspase inhibition, cannabinoid receptor 2 agonists for the treatment of neuropathic pain, etc. In this study, N-alkyl/benzyl isatin derivatives were synthesized from isatin and alkyl/benzyl halides in presence of K₂CO₃ in DMF and excellent to quantitative yields (~95%) were obtained. Isatins and benzyl-isatins were condensed with fluorescein hydrazide to form fluorescein hydrazone. All the compounds were subjected to their fragmentation behavior study using LC/MSⁿ. N-Alkyl substituted isatin derivatives fragmented at nitrogen-carbon (N-C) bond, hence gave daughter ion as [RN+H]⁺. Whereas, N-benzyl substituted isatin derivatives fragmented at carbon-carbon (C-C) bond of alkyl chain which linked with nitrogen molecules, therefore gave N-methyl fragments [RNCH₂]⁺. This study demonstrated that, isatin moiety present in a small/large molecule or in a matrix of reaction mixture with/without N-alkyl/benzyl substituents can be identified by mass spectroscopic fragmentation behavior study.

It is important for nurses to try to improve their interpersonal relationship and communication skill. The purpose of this study was to examine the nurse's inerpersonal conflict and expression with physicians, other nurses and patients & their caregivers. A convenient sample of 62 RN-BSN students were recruited. The data collection was done from August, 2001 to September, 2001. Nurses experienced the most conflicts with high-positioned nurses, then doctors, patients and their families, administrators, nurse-aid, nurse colleagues and lower-positioned nurses. There was a significant correlation between nurse's interpersonal conflict with doctors and nurse's age & career, between with high-positioned nurses and region of hospitals & nurse's position. The expression that nurses least-like from physicians was 'Do it as order'. From other nurses was 'manner of speech such like order'. And from patients and their family was 'naming such like young lady or sisters'. The other side, the expression that nurses most like expression from physicians and ohter nurses was 'You are excellent'. From patients and their family was 'You are kindness'. In conclusion, it is necessary to improve nurse's communication skills and interpersonal relationships.

Time-loss injuries are still a major occurrence in Canada, injuring thousands of Canadian workers each year. With obesity rates on the rise across the country, as well as around the world, it is important that the possible effects of obesity in the workplace be fully understood, especially those effects linked to lost-time injuries. The aim of this paper was to evaluate predictors of workplace lost-time injuries and how they may be related to obesity or high body mass index by examining factors associated with lost-time injuries in the health care sector, a well-studied industry with the highest number of reported time loss injuries in Canada. A literature review focusing on lost-time injuries in Registered Nurses (RNs) was conducted using the keywords and terms: lost time injury, workers' compensation, occupational injury, workplace injury, injury, injuries, work, workplace, occupational, nurse, registered nurse, RN, health care, predictors, risk factors, risk, risks, cause, causes, obese, obesity, and body mass index. Data on predictors or factors associated with lost-time injuries in RNs were gathered and organized using Loisel's Work Disability Prevention Management Model and extrapolated upon using existing literature surrounding obesity in the Canadian workplace.

본 논문에서는 레지듀 연산(residue arithmetic)을 사용하여 디지탈 필터를 실현하는 한 가지 방법을 제시 하였다. 기존의 레지듀 디지탈 필터가 비교적 적은 비트 수를 갖는 신호만을 처리할 수 있었던 것에 비해, 여기서는 비트 슬라이스 알고리즘[1]의 원리를 적용함으로써 보다 많은 비트 수를 갖는 신호를 처리할 수 있도록 했으며, 또한 레지듀 가감산 및 승산은 연산표에 의해서 고속으로 수행될 수 있으므로 이를 이용하여 비트 슬라이스 알고리즘의 단점인 융통성 (flexibility)의 문제를 해결하였다. 실제로 종속 접속형 4차 버터워즈 저역통과 디지탈 필터를 구성하여 실험함으로써 이와 같은 사실들을 입증할 수 있었다.

Purpose: This study was to develop nursing competencies, sub-competencies and behavior indicators according to the clinical ladder of emergency nurses. Method: index of content validation was used by 21 clinical experts. Results: This study had three phases to develop nursing competencies, sub-competencies and behavior indicators. In first phase: 12 nursing competencies and 33 sub-competencies were developed through the literature review on nursing competency and emergency nurses' job description. The content of 12 competencies and 33 sub-competencies were reviewed by 3 nursing professors. The 12 competencies and 33 sub-competencies were followed: clinical judgement and measures(6 sub-competencies), processing ability of ward works(2 sub-competencies), flexibility(2 sub-competencies), resources management(2 sub-competencies), confidence(3 sub-competencies), cooperation(2 sub-competencies), professional development power(2 sub-competencies), patient service orientation(3 sub-competencies), inclination toward ethical value(5 sub-competencies), influence power(2 sub-competencies), developing others(2 sub-competencies), self control(2 sub-competencies). In second phase, 132 behavior indicators were developed according to nurse clinical ladder: novice, advanced novice, competent, proficient. In Third phase, content validity was examined on 132 behavior indicators by 21 clinical experts. 126 among 132 indicators had over 70% agreement among experts and 6 indicators under 70% were revised. Conclusion: nursing competencies, sub competencies and behavior indicators can be used nurses' clinical performance as well as establishing proper directions for professional growth related to reward system.
