In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

( Ji Su Lee ),( Hyun-sun Park ),( Hyun-sun Yoon ),( Soyun Cho ) 대한피부과학회 2018 대한피부과학회 학술발표대회집 Vol.70 No.2

Background: Actinic keratosis (AK) is a common sun-induced skin disorder of importance for the progression to invasive squamous cell carcinoma. However, there is still no good way to predict high risk AK. Objectives: To identify markers which reflect the biologic behavior of AK and to understand the pathogenesis of AK Methods: A total of 52 patients with AK and site-matched 17 normal controls were included. We evaluated solar elastosis and immunohistochemical features using the following antibodies: p53, vitamin D receptor (VDR), claudin-1, and Langerin. Results: Solar elastosis increased and Langerhans cell (LC) density decreased with aging in both patients and controls. Solar elastosis and p53 expression were higher and VDR expression was lower in patients than controls; however, they showed no statistical difference in relation to the pathologic grade of AK. Claudin-1 expression gradually decreased from normal control to severe AK and decreased in the areas with epidermal atypia. LC density in severe AK was significantly lower than in normal control and mild AK; no difference in LC density was seen among control, mild AK and moderate AK. Conclusion: Claudin-1 can be a useful marker of pathologic severity of AK. In contrast, p53 increases and VDR decreases in AK not in gradual manner but in the early steps of carcinogenesis. LC density is relatively maintained in AK until it reaches severe dysplasia.

A multiplex polymerase chain reaction (PCR) method was developed to simultaneously detect 3 events of genetically modified (GM) maize. The event-specific primers were used to discriminate the following 3 events of GM maize (DAS-59122-7, TC6275, and MIR604) using multiplex PCR method. The zein gene was used as an endogenous maize reference gene in the multiplex PCR detection. The primer pair Zein-F/R producing a 99 bp amplicon was used to amplify the zein gene. The primer JI-Das-F1/R1 for DAS-59122-7, JI-TC6275-F3/R3 for TC6275, and JI-MIR F1/R1 for MIR604 yielded an amplicon of 130, 162, and 197 bp, respectively. The detection limit of multiplex PCR was 1% for DAS-59122-7, TC6275, and MIR604 for one reaction.

Ultraviolet (UV) is thought to induce erythema, sun-burn, photo-toxicity, photo-allergy, photo-aging and sometimes skin tumor. To investigate the photo-protective effects of APB-01 (Amore-<br/> Pacific Beauty-01, the mixture of Jaummi-dan and Fujiflavone P10) on UV-induced skin damage, forty of SKH hairless female mice were orally administered with APB-01 or saline fifth a week, and irradiated with UV third a week for up to ten weeks. We examined the relationship between visible changes and skin damage in the dermis and epidermis. In the APB-01 treated group, a better skin<br/> and less wrinkles formation were observed when compared to the UV control group. This results demonstrated that oral administration of APB-01 seems to have photo-protective effects on UV-induced<br/> skin damage of hairless mice due to an inhibitory effect on collagen breakdown, and the model using hairless mice is very useful to investigate the efficacy of functional beauty foods.

Pesticides were extracted from samples with 70% acetone and methylene chloride in order, and then cleaned up via open-column chromatography apparatus packed with florisil, and finally analyzed simultaneously the organochlorine and pyrethroid pesticides using GC(ECD). An ultra-2 fused silica capillary column was used to separate and identify the products. The resolution between the last isomeric peak of cypermethrin(59.987min) and the first isomeric peak of flucythrinate(60.043min) was not satisfactory. The last isomeric peak of fenvalerate(62.344min) and the first isomeric peak of fluvalinate(62.397min) were overlapped. Recoveries of soybean sample for the most pesticides were 73.3% to 102.4%. Detection limits were between 0.004 and 0.063 ㎍/㎎ when this method was used.

이지선,엄정애 이화여자대학교 교육과학연구소 2022 교육과학연구 Vol.53 No.1

본 연구는 유아들의 실외놀이에서 발생하는 또래갈등 원인과 또래갈등 해결전략, 이후의 놀이변화 탐색을 목적으로 진행되었다. 연구자료는 강원도에 위치한 다은유치원 만 5세 정운반의 유아 18명(남아 7명, 여아 11명)과 교사 1명을 연구 참여자로 하여 총 21회의 참여관찰 및 면담을 통해 수집되었다. 연구결과, 첫째, 실외놀이에서 유아들의 또래갈등 원인은 물리적 원인과 관계적 원인으로 양분되었다. 물리적 원인은 고정놀이기구 선점권과 한정된 놀잇감 소유권, 놀이구성물 훼손으로 나타났으며 관계적 원인은 지식과 경험에 대한 의견충돌, 상대가 원하지 않는 장난, 신체적 접촉으로 나타났다. 둘째, 유아들이 실외놀이에서 발생한 또래갈등을 해결하기 위해 사용한 갈등해결전략은 일방향적인 해결전략, 상호적인 해결전략, 제3자 개입전략으로 나타났다. 마지막으로, 갈등해결전략 사용 후 유아들의 놀이변화는 놀이 확장, 놀이틀로 복귀, 놀이소멸로 나타났다. 놀이틀로 복귀는 완전한 갈등해결을 통한 놀이복귀와 불완 전한 갈등해결을 통한 감정 표출하기의 하위범주로 분류되었다. 본 연구는 ‘실외놀이’라는 공간에서 발생한 또래갈등의 전 과정을 총체적으로 분석하여 또래갈등 연구에 대한 스펙트럼을 넓힐 수 있을 뿐만 아니라 또래갈등의 시작과 전개, 종결과 이후 상황에 이르기까지의 전 과정에 대한 이해를 도모하고, 교사의 개입과 역할에 대해 다시 생각해 볼 수 있는 계기를 마련하였다는 점에서 의의가 있다. This study was conducted with the purpose of exploring the causes of peer conflict, peer conflict-solving strategies, and subsequent changes in play that occur in the outdoor play of young children. The research data were collected through a total of 21 participatory observations and interviews with 18 young children (7 boys and 11 girls) and 1 teacher in the 5-year-old Jeong-un class at Daeun Kindergarten located in Gangwon-do, Korea. As a result of the study, first, the causes of peer conflict among young children in outdoor play were divided into physical causes and relational causes. Physical causes were the preoccupation with play equipment, ownership of a limited amount of toys, and damage to play components. Relational causes were conflicts of opinion on knowledge and experience, and unwanted mischief and physical contact. Second, the conflict-solving strategies used by young children to solve peer conflicts that occurred in outdoor play were one-way resolution strategies, mutual resolution strategies, and third-party intervention strategies. Finally, after using the conflict-solving strategies, the changes in play of young children were found to be expansion of play, return to play framework, and extinction of play. Return to play framework was classified as a subcategory of returning to play through complete conflict resolution and expressing negative emotions through incomplete conflict resolution. This study can help broaden the scope of peer conflict research by comprehensively analyzing the entire process of peer conflict that occours in outdoor play. It is also meaningful in that it provides an opportunity to rethink the teacher’s role in conflict resolution.

Objectives : Vulnerability marker in biological relatives of schizophrenia may be very useful in identifying the propensity for the development of schizophrenia. This study suggests that the relatives at risk for genetically developing schizophrenia have impairments in several domains of cognition, social function and affective function as a vulnerability marker. Methods : A neurocognitive function test, a social function test and an affective function test were administered to fifteen healthy relatives from families with two or more patients with schizophrenia (geneticallly high risk subjects). Fifteen healthy controls matched for age and gender were recruited in this study. Results : Compared to the control subject, the genetic high risk subjects performed significantly more poorly in the selective attention and recall memory of neurocognitive function. The high dsk subjects also had lower scores in independence-performance and independence-competence of the social function test and emotion control of the affective function test. Conclusion : Selective attention, recall memory, independence-performance, independence-competence and emotion control ability may be a valuable marker for genetic study of schizophrenia.
