Micropollutants emerge in surface water through untreated discharge from sewage and wastewater treatment plants (STPs and WWTPs). Most micropollutants resist the conventional systems in place at water treatment plants (WTPs) and survive the production of tap water. In particular, pharmaceuticals and endocrine disruptors (ECDs) are micropollutants frequently detected in drinking water. In this review, we summarized the distribution of micropollutants at WTPs and also scrutinized the effectiveness and mechanisms for their removal at each stage of drinking water production. Micropollutants demonstrated clear concentrations in the final effluents of WTPs. Although chronic exposure to micropollutants in drinking water has unclear adverse effects on humans, peer reviews have argued that continuous accumulation in water environments and inappropriate removal at WTPs has the potential to eventually affect human health. Among the available removal mechanisms for micropollutants at WTPs, coagulation alone is unlikely to eliminate the pollutants, but ionized compounds can be adsorbed to natural particles (e.g. clay and colloidal particles) and metal salts in coagulants. Hydrophobicities of micropollutants are a critical factor in adsorption removal using activated carbon. Disinfection can reduce contaminants through oxidation by disinfectants (e.g. ozone, chlorine and ultraviolet light), but unidentified toxic byproducts may result from such treatments. Overall, the persistence of micropollutants in a treatment system is based on the physico-chemical properties of chemicals and the operating conditions of the processes involved. Therefore, monitoring of WTPs and effective elimination process studies for pharmaceuticals and ECDs are required to control micropollutant contamination of drinking water.

A powerful tool for chicken transgenesis could be established by employing a germline chimera production through primordial germ cell transplantation. This study was conducted to examine whether foreign gene-transfected gonadal primordial germ cells (gPGCs) have a migration activity into the gonad after transfer to recipient embryos. In Experiment 1, gPGCs of Korean Ogol Chicken were retrieved from 5.5-day-old embryos and subsequently transferred to the dorsal aorta of 2.5-day-old White Leghorn embryos after being labeled with PKH26 fluorescent dye. To confirm migration activity after transplantation, recipient embryos were sacrificed and examined on 3 days after transfer. Sex determination was concomitantly undertaken to examine whether sex of recipient embryos could affect the migration activity of gPGCs. All of embryonic gonads examined showed positive signals with PKH26 fluorescence and W-chromosome specific band by polymerase chain reaction (PCR) was detected in male embryos when gPGCs with ZW chromosome were transferred to recipient embryos. In Experiment 2, retrieved gPGCs were transfected with LacZ gene-containing cytomegalovirus promoter ($pCMV{\beta}$) by electroporation and subsequently transferred to recipient embryos. LacZ gene expression was identified in the gonads of 6 or 10-day-old recipient embryos and hatched-chicks. A total of 20 embryos and 12 hatched-chicks were examined and 11 of them (10 embryos and one hatched chicken; 11/32=34.4%) expressed $\beta$-galactosidase, a marker substance of LacZ gene. The results of this study demonstrated that foreign gene-transfected gPGCs can migrate and settle down into the gonad after being transferred into the blood vessel of the recipient embryos. This established technique will contribute to developing a peer biotechnology for transgenic chicken.

We would like to suggest the guideline of use of materials of sexual education for adolescent in school by examining the status of use of materials and by evaluating the video materials frequently used. Survey was done by enquetes on status of use of materials of sexual education from school nurses in 190 primary, 44 middle and 50 high schools in Seoul, Kyonggi-do and Kangwon-do from August 1999 to February 2000. The frequently used 84 videotapes were evaluated on their contents. As for the status of use, 99.3% of subjected schools possessed the materials for sexual education. Decision of purchase was determined according to the review of contents (92.6%). Information about materials was received by the advertisement in newspapers or broadcasting (46.1%) or recommendation of peer teacher (32.4%). Videotape was most frequently used (64.1%) rather than books or CD. Teachers concerns on the materials were the educational content according to developmental stage of students (41.9%), content provoking interest (33.5%) and concrete guide for teacher (10.6%). As for the evaluation of the contents of videotapes, a subject of education was not described out of 46.6%. Videotape producer were mostly the Government-affiliated institutes or non-profit organizations (86.8%). The year of production was indicated from 41.7%. Running time range of 21-30 minutes was highest (55.9%). The price was marked in only one videotape. Subjects of contents were general sexual education (34.5%), sexual violence or sexual harassment (21.4%), pregnancy and contraception (14.2%) and AIDS and sexually transmitted diseases (8.3%) and dating and adolescent change (4. 8%), and etc (11.9 %). According to above results, we suggested that materials for sexual education should be completed with a description on the subjected group, summary of content, information on the tape producer, year of production, running time and sale price.

Purpose: Social media's increasing adoption and the development of digital technology have completely changed how businesses interact with their clients. The current study is to examine the impact of live broadcasts on consumers' perceptions and actions across a range of fresh food goods. Research design, data and methodology: The scrutiny relies on the existing peer-reviewed literature, which may prevent a comprehensive evaluation of some recent advancements in the subject. Despite these caveats, the outcomes of this scrutiny are anticipated to contribute significantly to our understanding of the effect of live broadcast marketing on consumers' propensity to make purchases. Results: Previous literature review clearly states that 'Live Broadcast of Fresh Food' to attract relevant customers should be followed: (1) Increased Product Transparency and Trust, (2) Enhanced Customer Engagement, (3) Impact on Customer's Perception of Product Quality, and (4) sense of urgency and scarcity. Conclusions: All in all, the study's advice for firms in the food industry to improve their marketing efforts through live broadcasts have important practical ramifications. Promoting openness and trust in the production process and with the audience boosts a brand's reliability. Customers are more likely to participate and feel more connected to a brand.

본 연구에서는 대한의학학술지편집인협의회가 1997년부터 1999년 사이에 평가한 76종의 국내 의학학술지가 받은 총 33개 평가항목의 각 항목별 평가점수와 총평점의 분포, 그리고 이들의 상관관계를 분석하여 각 평가지표의 변별력을 측정하였다. 한국 의학학술지의 대표적인(변별력이 높은) 평가지표는 투고논문의 상호심사와 관련된 평가항목과, 학술지가 일정한 형식으로 일관성 있게 잘 만들어지고 있는지를 평가하는 항목으로 판명되었다. 논문상호심사제도(peer review system)가 학술지의 질관리에 있어서 매우 중요하다는 것은 주지의 사실이다. 학술지의 철저한 편집(quality of editorial work)과 출판품질 관리(production quality)가 학술지 평가의 좋은 척도가 될 수 있다는 것은 학술지 평가사업의 경제성과 효율성의 측면에서 매우 고무적인 일이다. 편집인 교체빈도나 연간 발행회수 등은 변별력이 거의 없는 평가지표로 나타났다. 평가대상 학술지가 우리나라 의학도서관에 비치되어 있는 정도나 권말색인 작성여부 등 변별력이 낮은 평가항목의 변별력을 높이기 위해서는 평가방법의 개선이 필요하며, 자체학술지 인용비율, SCI 인용빈도나 영향력지표 등의 평가항목은 평가배점 구간의 조정이 필요한 것으로 나타났다. SCI에서의 인용과 국제 데이터베이스 등재여부만이 아니라, 국내 학술지가 인용하는 빈도나 영향력지표, 국내에서 구축되고 있는 의학관련 데이터베이스 등재 여부, 레코드 입력율 등의 새로운 평가지표 개발이 필요하다.

Body shape of a child in elementary school is distinguished by physical differences in the form of low weight, normal weight and obesity, which are influenced by various periodic environments. In particular, there are hardly any patterns for obese children in elementary school to choose. To this end, the purpose of this study is to supplement the problems with the production lines of the companies for children's patterns as well as an analysis on the physical characteristics of obese children and to suggest the patterns appropriate to obese children. This study employed obese children from the 3rd- to 5th-grade elementary school students whose number has been rapidly increasing and conducted a questionnaire regarding the draft of the patterns for obese children on their mothers and the makers of children's clothing. Based on the results, the study compared and analyzed ordinary children's patterns to the patterns in question by suggesting a dimension system for Korean obese children. The results are as follows. The obesity rate of the children in elementary school has been grown in significant numbers every year, whereas obese children's sense of self-identity and degree of satisfaction with their patterns appeared to be much lower than other ordinary children in the peer group; also, the satisfaction level their mothers with their children's patterns appeared to be low. In order to verify the degree of the children's satisfaction with their patterns, the study suggested a dimension system for the obese children and displayed appropriateness by comparing the children patterns from ordinary companies and the patterns in question.

In modern society, the amount of alcohol ingestion is increasing at a dangerous level, especially among women. One of reason for increased alcohol consumption is stress caused by social pressures. Alcohol is a kind of depressant of centric nervous system, so it can induce relaxation of body and decrease the stress. The evidence on the effects of alcohol on the fetus is somewhat hazy, whereas that of smoking is quite clear. The literature on the ingestion of alcohol strongly suggests that drinking during pregnancy is associated with teratogenic effect and low birth weight. Therefore, the adverse effect of alcohol ingestion during pregnancy must be informed to public. More remarkable warning sign about alcohol ingestion must be attached on the top of bottles. This can be an effective measure for public education. Also legal sanction or tax imposition for the production of liquor be required. First of all, drinking habit or drinking culture must be changed. In fact, the strongest motivation of drinking in adolescent is a peer pressure which is related to drinking habit or culture. Secondly, early detection and treatment must be required to prevent from fetal alcohol syndrome. Accordingly, drinking history of pregnant women must be assessed as early as possible and health professional should give a warning about the abstinence of alcohol to drinking women. Thirdly, to minimize the adverse effects for mother, withdrawal syndrome by alcohol ingestion must be treated. to correct the malformation by fetal alcohol syndrome(FAS) can be corrected. Sometimes surgical intervention may be required for this purpose.
