Objectives : This study describes a plan that was designed to prevent a measles outbreak that showed a changed outbreak pattern. This study is based on the epidemiological investigation of a measles outbreak in a preschool in Incheon, Korea, 2006. Methods : The subjects were 152 students at a preschool where a measles outbreak occurred. A questionnaire survey was conducted and serological testing for measles-specific IgM was preformed. Results : Of the fifteen confirmed, identified cases, eleven patients had been vaccinated with one dose, one patient had received two doses and three patients were unvaccinated. The three unvaccinated cases consisted of one 5-year-old child, one 3-year-old child and one 16-month-old infant. For the cases with one dose of the vaccination, there were 11 cases, which consisted of six 5-year-old children, two 4-year-old children, two 3-year-old children and one 2-year-old child. The case with two doses of the vaccination was one 4-year-old child. The attack rate of measles was 100% in the 0-dose group, 11.2% in the 1-dose group and 2.0% in the 2-dose group. The vaccine's efficacy was 88.8% in the 1-dose group and 98.0% in the 2-dose group. The vaccine effectiveness for the 2-dose group was higher than that of the 1-dose group. Conclusions : High coverage with a 2-dose vaccination should be maintained, and the vaccination should be given at the suitable time to prevent a measles outbreak with a changed outbreak pattern.

Based on the Vygotskian perspective that a learner's thinking is constituted in his or her talk and the assumption that student talk in the classroom may occur in more than one way, this study examined discursive practices of students in Korean high school science classrooms. Data came from $11^{th}$ grade earth science classrooms where the Group Investigation (GI) method was implemented. Data source included verbatim transcripts developed from video recordings of class sessions in which students presented their science projects to the whole class and exchanged questions and answers during the presentations. The analysis of the videotape transcripts revealed five different modes of student talk, including 1) retrieving information, 2) reformulating information, 3) building on one's own experience, 4) elaborating current understanding, and 5) negotiating meanings with others. Considering that each of the five modes had different value for learning science, it was recommended that the teacher should engage students in more active modes of discourse and guide them into more sophisticated understanding of science.

Microglia are the confined immune cells of the central nervous system (CNS). In response to injury or infection, microglia readily become activated and release proinflammatory mediators that are believed to contribute to microglia-mediated neurodegeneration. In the present study, inflammation was induced in the immortalized murine microglial cell line BV-2 by lipopolysaccharide (LPS) treatment. We firstly performed phosphoproteomics analysis and phosphoinositide lipidomics analysis with LPS activated microglia in order to compare phosphorylation patterns in active and inactive microglia and to detect the pattern of changes in phosphoinositide regulation upon activation of microglia. Mass spectrometry analysis of the phosphoproteome of the LPS treatment group compared to that of the untreated control group revealed a notable increase in the diversity of cellular phosphorylation upon LPS treatment. Additionally, a lipidomics analysis detected significant increases in the amounts of phosphoinositide species in the LPS treatment. This investigation could provide an insight for understanding molecular mechanisms underlying microglia-mediated neurodegenerative diseases.

This study aimed at defining radish cultivars to a best cooking usage based on their physiochemical and textural characteristics of Nabakkimchi. Baekkwang, Daeburyong, Chungwoon and Taebaek were used as four types of radish cultivars. Nabakkimchi was stored at $8^{\circ}C$ either after fermentation for 12 hours at $25^{\circ}C$(A group) or without preliminary fermentation(B group). As storage period went by, lightness was decreased. Haziness of liquid showed sudden increase at preliminary fermentation in group A, while it increased between the third day and fifth day in group B. Hardness of 'Fall season' type was relatively high after storage. pH was suddenly decreased on the second day in A group and on the fifth day in B group. Acidity was suddenly increased on the second day in A group and since the third day at B group. As a result of sensory evaluation, Chungwoon stored for 2 days after preliminary fermentation was the best variety.

2020. 2.경 대한민국에서 코로나19 감염증의 대유행이 시작될 당시 문제가 되었던 대구 지역 A종교단체의 역학조사 방해 사건을 중심으로 면밀히 검토한 결과, 역학조사관이 특정 단체에게 명단 제출을 요구하였을 때, 이에 불응하거나 편집된 누락 명단을 제출한 행위에 대하여 역학조사에 해당하지 아니한다는 취지로 선고된 사례가 있는 반면, B열방센터 행사 출입자명단 미제출 사건의 경우 '출입자 명단' 등을 요구받았음에도 정당한 이유 없이 거부한 사실에 대하여 '출입자 명단의 제공은 역학조사에 수반되는 역학조사 간의 연결 과정을 형성하는 핵심적 사실행위로, 이를 거부하는 것도 역학조사 거부, 방해행위에 해당'하므로 적법하게 명단을 요구할 수 있어 처벌이 가능하다는 사례도 있다. 교인명단 제출요구가 역학조사에 해당하는지 여부와 관계없이 교인명단 제출 거부 또는 누락 행위가 곧 역학조사 거부·방해행위에 해당하는 경우도 있는데, 역학조사와 직접 관련성, 역학조사를 위한 것임이 외부적으로 표시되어 인식되었는지 여부, 명단의 역학조사 외의 목적으로 전용될 가능성 등을 종합적으로 고려하여 역학조사에 수반되는 사실행위를 방해함으로써 결과적으로 역학조사가 거부 내지 방해되는 결과가 발생한 경우에는 역학조사 방해가 된다는 하급심 판결의 논리가 설득력이 있다. 역학조사 결과 확인된 각 감염병환자등이나 접촉자 등에 대해 설문조사나 인체검체 채취 및 시험과 같은 역학조사가 실시되지만, 개별적인 사람에 대해 실시되는 역학조사가 서로 독립하여 존재할 수 없으며 역학조사의 연결 과정을 확인하고 추적하는 과정이 역학조사에 필수적으로 수반되며 이러한 연결고리를 확인하는 과정을 누군가 고의로 방해하거나 거부하게 되면, 역학조사가 직접적이고 현실적으로, 광범위하게 방해되는 결과가 발생하기 때문이다. 이 글에서는 주로 ① 감염병예방법상 역학조사와 정보 제공 요청은 차이점이 있으나 정보 제공 요청의 경우에도 역학조사에 해당되는 영역이 있다는 점, ② 코로나19의 의학적 특성과 역학조사의 연속성을 감안하면 역학조사관의 명단요구 행위가 역학조사에 해당할 여지가 있다는 점, ③ 특정한 경우에는 역학조사 방해죄가 위계공무집행방해에 해당할 수 있다는 점, ④ 2020. 9. 29.부터 감염병예법상 정보제공요청을 거부하는 경우에 징역형 또는 벌금형의 처벌규정이 신설되어 운용되고 있다는 점 등을 지적하여, 향후 감염병예방법의 적용 및 역학조사 실무 운용에 있어 도움이 되고자 한다.

Objective: To investigate the clinical effect of riboflavin sodium phosphate on prevention of radiotherapy related esophagitis (RRE). Methods: This retrospective study involved 55 patients with middle and advanced esophageal cancer who were divided into an experimental group of 28 and a control group of 27 patients. Those in the experimental group were treated with riboflavin sodium phosphate combined with conventional symptomatic treatment during radiotherapy; while patients in control group received the latter alone. The incidence and degree of RRE were compared after radiotherapy. Results: The incidences of RRE in experimental and control group were 53.5% and 81.4%, respectively (p<0.05); the incidence of stages III and IV RRE in the experimental group was 17.8%, while in the control group it was 44.4% (p<0.05). Conclusion: Riboflavin sodium phosphate could significantly prevent RRE and reduce the incidence of stage III and IV disease. These results were worthy of further confirmation by randomized controlled trials.

An investigation of the effect of occupational information on vocational cognitive complexity was conducted with 331 male and female adolescents in ninth grade. There were 2 experimental groups and 1 control group. Experimental group I was given only occupational information sheets (written form information) while group II was given occupational information through verbal instruction in addition to the occupational information sheets. A modified form of the cognitive complexity grid originally developed by Bodden (1970) was utilized to collect data on the subjects' vocational cognitive complexity. ANOVA and $Scheff{\acute{e}}$ tests revealed that there were significant differences between experimental group II and the other groups in vocational cognitive complexity. The cognitive complexity level of experimental group I and the control group for the most aspired occupation was significantly lower than for the least aspired occupation. However, the cognitive complexity level of experimental group II for the most aspired occupation was higher than for the least aspired occupation. The results suggest that just giving occupational information to adolescents may not be effective and giving occupational information may be effective only when the method of giving occupational information is active enough to induce adolescents' self-confirming cognitive process.

In this study, I used wood pellets as an eco-friendly sound-absorbing material. The aim of the research was to analyze the effect of the filling height of wood pellets on sound absorption. This was done using two types of wood pellets of different lengths (A group: 1.5-3 cm, B group: less than 1.5 cm). With increasing filling height of the wood pellets, the optimum sound absorption shifted towards a lower frequency. The group B wood pellets had better sound absorption capacity than the group A ones. The optimum sound absorption coefficient of group A filled to a height of 7 cm was 0.722 at 864 Hz. On the other hand, that of group B filled to a height of 7 cm was 0.764 at 862 Hz, 5.82% higher than that of group A. While wood pellets are used as an eco-friendly fuel, the results of this study suggest the possibility of using wood pellets as an eco-friendly sound-absorbing material.
