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.

비틀림을 받는 RC 및 PC부재의 균열폭 계산방법에 관한 연구
박선규 成均館大學校 科學技術硏究所 1996 論文集 Vol.47 No.2
Since the highstrengthed steel and concrete is used in RC and PC structure, more and detailed design method is used and the section of member has also reduced. The crack in the design became an importanen. When the highstrengthed steel inside the member is used under high stress, the width of crack in concrete is significantly generated. This crack is not only given a rough surface in the exterior but also deteriorated the durability of the structure due to eroding. By this time, the study of crack generated from bending and tensional force has been activited in many nations. In the design method to maintain the serviceability and the durability, the width of crack in the standard code used in present has proposed according to the enviromental condition. The crack problem of RC and PC member under the tensional force has not been enough studied. The objective of this study is to derive the formula for calculating the width of crack on PC member under the pure tensional force among the methods of restricting the width of crack. This study will be contributed to the design method for the evaluating of serviceability.

A adaptive filter structure based on the subband decomposition of FIR filter using the wavelet transform is designed and tested. There is no sampling rate alternation in this structure and therefore no aliasing problem occurs. The adaptive noise reduction characteristics using the Harr wavelet transform and DFT are presented and compared. The structure using the Harr wavelet transform is computationally efficient compared to the DFT(FFT) method.

There are not problems in the discrete variation, but there are problems in the continuous variation in teaching the representative value. I studied the case of the continuous variation in calculating the median value and high frequency, and mentioned the characteristic of the mean value, the median value and the high frequency, too. When the representative value is decided, we are needed to know the distributional figure and the purpose of using and select the suitable one, because there is not an ideal representative value, and the characteristics of the representative value are different.

I described about the principle of mathematical induction method and the adaptation of it. In applying to the principle the matters for notice are as follows: There being a certain natural number S proving when n=m at the second step, when the case (n=m-1, n=m-2, n=m-S) must use being true, we must certify the case (n=1, n-2,··· n=S) at the first step and must do the proof of the second step.

The concept of transform domain adaptive filtering is introduced. In certain application, filtering in the transform domain results in great improvements in convergence rate over the conventional time domain adaptive filtering. The frequency domain transform is several existing. The two type of adaptive filtering in transform domain can be accomplished by Fourier transform and Wavelet transform. In this paper, compared and characterized performance of noise reduction

In two dimensional table percentage is calculated generally in the direction of cause factor. According to the nature of sample, pro and con of calculating percentage was come to right. 1) When Sample represents the direction of cause factor, Cause and Effect rule can't be applied. 2) When Sample represents Total Sample, calculation is possible in any direction. 3) When Total Coum itself dose not represent Total Population, Total Colum can't be indicated.

본 연구는 스트레스 반응을 측정하는 스트레스 반응 척도 설문지(Symptoms of Stress: SOS)를 이용한 횡단적 연구로서 심신수련의 하나인 기수련이 스트레스 반응에 미치는 효과를 살펴보았다. 72명의 건강한 정상인과 180명의 기수련자를 대상으로 하여 조사하였으며, 기수련자들은 수련기간에 따라 초급군(1-4개월; 64명), 중급군(5-12개월; 50명), 고급군(1년 이상; 66명)로 나누었다. 실험결과 1년 이상 수련한 기수련자들이 말초혈관 증상군, 심폐 증상군, 중추신경계 증상군, 위장계증상군, 습관적 행동 형태군, 우울 증상군, 불안증상군등의 스트레스 반응 하위척도에서 대조군에 비해 통계적으로 유의하게 감소하였다. 전체 스트레스 값은 대조군에 비해 기수련자 집단이 아주 낮았으며 수련기간이 길수록 감소하였다. 이러한 결과는 기수련이 스트레스 중재와 스트레스 증상을 줄이는데 효과가 있음을 나타낸다. We examined the effects of Qi-training, one of Korean traditional psychosomatic training, on stress coping ability by cross-sectional investigation with inventory of symptoms of stress (SOS). Four types of groups- normal healthy (n-74), three groups of Qi-trainees (group primary level: subjects with Qi-training for 1-4months, n=64; middle level: 5-12 months, n=50; high level: more than 12 months, n=66) participated in this study, Qi-trainees with over 1 year training had significantly lower scores in all SOS subscales compared to controls. Total stress scores of Qi-trainee groups were substantially lower than controls and further reduction with larger training periods. These results suggest Qi-training is effective in stress management and decreasing symptoms of stress
