Background: Genetic alterations have been identified in melanomas according to different levels of sun exposure. Whereas the conventional morphology-based classification provides a clue for tumor growth and prognosis, the new classification by genetic alterations offers a basis for targeted therapy. Objective: The purpose of this study is to demonstrate the biological behavior of melanoma subtypes and compare the two classifications in the Korean population. Methods: A retrospective chart review was performed on patients found to have malignant melanoma in Severance Hospital from 2005 to 2012. Age, sex, location of the tumor, histologic subtype, tumor depth, ulceration, lymph node invasion, visceral organ metastasis, and overall survival were evaluated. Results: Of the 206 cases, the most common type was acral melanoma (n=94, 45.6%), followed by nonchronic sun damage-induced melanoma (n=43, 20.9%), and mucosal melanoma (n=40, 19.4%). Twenty-one patients (10.2%) had the chronic sun-damaged type, whereas eight patients (3.9%) had tumors of unknown primary origin. Lentigo maligna melanoma was newly classified as the chronic sun-damaged type, and acral lentiginous melanoma as the acral type. More than half of the superficial spreading melanomas were newly grouped as nonchronic sun-damaged melanomas, whereas nodular melanoma was rather evenly distributed. Conclusion: The distribution of melanomas was largely similar in both the morphology-based and sun exposure-based classifications, and in both classifications, mucosal melanoma had the worst 5-year survival owing to its tumor thickness and advanced stage at the time of diagnosis.

The purpose of this research was to analyze the needs assessment of beginning teacher’s job competence in elementary schools. For this purpose, an on-line questionnaire was created and sent to 14,398 teachers in 17 Local Education Provinces. The questionnaire composed of 10 areas related to job skills of beginning teachers. The result of survey indicated that the priority of job competencies required for beginning teachers are ‘student guidance and counseling’ and ‘conjunction with parents and the community’. For future the competence of elementary school teachers, ‘the actual problem solving skills’, ‘relationship skills’, ‘communication skills’, ‘patience’, and ‘conflict management skills’ appeared to be needed. Furthermore, programs to enhance job competences in the future should involve ‘mentoring’ and ‘school based peer supervision’. This research concludes with these practical suggestions; First, on-the-job training needs to be strengthened to develop the expertise of beginning teachers. Second, in order to improve the job competence of new teachers in newly appointed elementary teachers, a training program to identify the needs new teachers needs to be developed. Third, the teachers’ appointment and rotation policy are needed to be reconsidered.

The purpose of this study was to evaluate the iron status of 39 female adult who divided into five groups according to the stress condition. The iron status was evaluated based on dietary intake and blood analysis. The average age of the subjects was 23.10years, and the average score of BMI was 20.06kg/m2. The proportion of subjects in each stress condition was : 2.56%(1) in A1type(the group who easily get disease associated with stress), 64.10%(25) in A2type(condition susceptible to the disease associated with stress), 30.77%(12) in ABtype(middle type of A and B), 2.56%(1) in B2type(appropriate stressed condition) and 0%(0) in B1type(risk free to the disease associated with stress). The average daily intake of energy in study subjects was 2,399kcal, ti caloric ratio of carbohydrate, protein, fat was 59.90 : 14.39 : 25.71, respectively. There was no significant difference in anthropometric measurements, dietary intake status, hematologic indices of iron status between high stress group(A1type and A2type) and low stress group(ABtype and B2type). To compare the iron stores between high stress group and low stress group, subjects in each group were devided into iron 0 mg, 250 mg, 500 mg group. Stress level did not affect iron stores although in both groups, number of subjects in iron 0 mg group were higher than those of iron 250 mg and 500mg groups. Correlation coefficients between anthropometric measurements, nutrient intake status, hematologic indices of iron status and stress score of subjects did not reveal any significance. Therefore, the results suggest that psychological stress did not affect the iron status in normal female adult. However, be more systematic study on stress and the iron status is required in the future.

This study was to investigate if cervical vertebrae maturation stages are as useful as hand-wrist maturation stages in evaluating the mandibular growth. The subject consisted of 292 girls aged from 8 to 16 years with normal occlusion. They were classified according to diagnosis by using studycast. lateral cephalogram, and handwrist X-ray film. The results were as follow: 1. Cervical vertebrae and hand-wrist maturation stages increased with age. 2. All mandibular measurements (Ar-Go, Go-Me, N-Go, S-Gn, N-Me) increased linearly with cervical vertebrae maturation stages. 3. Ar-Go, Go-Me, N-Go, S-Gn increased linearly with hand-wrist maturation stages. 4. Ar-Go, Go-Me, N-Go, S-Gn increased relatively rapidly between cervical vertebrae maturation stages 3 and 4. Go-Me and S-Gn increased relatively rapidly between hand-wrist maturation stages 6 and 7. 5. Ar-Go, Go-Me, N-Go, S-Gn, N-Me had high correlations with cervical vertebrae maturation stages as well as hand-wrist maturation stages. These results suggest that cervical vertebrae maturation stages are reliable on evaluating the mandibular growth. 하악골 성장을 평가하는 데 경추골 성숙도가 수완부골 성숙도만큼 유용한가 규명하고자 본 연구를 시행하였다. 정상교합을 가진 만 8세∼만 16세 여성 292명을 연구대상으로 하여 진단석고모형,측모두부규격방사선사진,그리고 수완부방사선사진을 이용하여 경추 및 수완부의 골성숙도를 비교하여 다음과 같은 결과를 얻었다. 1. 연령 증가에 따라 경추 및 수완부의 골성숙도가 일정하게 증가하였다. 2. 경추골 성숙도가 증가할수록 Ar-Go,Go-Me,N-Go,S-Gn,N-Me이 일정하게 증가하였다. 3. 수완부골 성숙도가 증가할수록 Ar-Go,Go-Me,N-Go,S-Gn이 일정하게 증가 하였다. 4. 경추골 성숙도 3단계와 4단계 사이에서 Ar-Go,Go-Me,N-Go,S-Gn이 크게 증가하였고,수완부골 성숙도 6단계와 7단계 사이에서 Go-Me,S-Gn이 크게 증가 하였다. 5.

녹차 및 매실추출물이 아질산염 소거, 전자 공여능 및 NDMA 생성 억제에 미치는 영향을 분석하고, 질산염과 아민이 풍부한 식단(CW)에 인공타액과 위액을 이용한 "simulated digestion" 에서 확인하였다. 녹차와 매실 추출물의 아질산염 소거작용을 pH 1.0, 4.2 및 6.0에서 실험 결과, pH가 낮을수록, 시료 첨가량이 많을수록 효과적이었으며 pH 1.2에서 녹차 추출물 0.5ml 첨가시킬 경우 99.6%의 높은 소거작용을 나타내었고, 매실 추출물 3ml 첨가시 77.2%의 소거작용을 나타내었다. 녹차 및 매실 추출물의 전자공여 작용은 각각 70.6%, 75.1%로 높게 나타났다. 녹차와 매실 추출물의 NDMA 생성억제 효과는 pH 1.2 에서 가장 뛰어났고, 시료량이 증가할수록 억제효과가 높아 3ml 첨가시에 82.1%와 73.2%의 억제효과를 나타내었다. 실험식이에 녹차 및 매실 추출물의 첨가량을 달리하여 인공소화시킬 때 NDMA 생성억제 효과는 시료 첨가량에 비례하여 각각 20ml 첨가시 녹차 추출물은 57.9%, 매실 추출물은 48.4%의 NDMA 생성억제 효과를 나타내었다. The effects of nitrite scavenging, electron donating and N-nitrosodimethylamine (NDMA) formation in vitro and green tea (Camellia sinensis) and Maesil (prunus mume) were studied. The green tea and Maesil extracts were tested for their nitrite-scavenging effect under the different pH conditions such as pH 1.2, 4.2 and 6.0. The effects of nitrite-scavenging in all concentrations were diminished in the alkali condition, whiled its effects in the acidic condition of pH 1.2 were reached of more than 99.0% by adding above 0.5ml of green tea extract. And also, nitrite-scavenging effect by adding 3ml of Maesil extract was about 77.0%. The electron donating ability (EDA) of green tea and Maesil extracts was 70.6%, 75.1%, respectively. The formation of NDMA was very effectiveness which was inhibited 82.1%, 73.2% at reaction mixture of pH 2.5 adding 3ml of above extracts, respectively. The ground CW, TW1 and TW2 (refer to Table 1) diets were incubated with 10ml simulated saliva and 40 ml gastric juice at 37℃ for 2hrs. NDMA formation was inhibited at all levels of green tea and Measil extracts.
