AWG의 파장교차특성과 광스위치를 이용한 WDM 시스템의 다채널 주파수 안정화

김광복,엄진섭,이정렬 강원대학교 정보통신연구소 1998 정보통신논문지 Vol.2 No.-

In this paper, we propose a novel multichannel frequency stabilization control scheme of semiconductor lasers, that uses the optical switches, wavelength crossover properties of an AWG, micro-processor and logarithmic amplifiers. The advantages of this scheme are that do not depend on the change of input power level and accommodate more channels simultaneously. Furthermore it can allow narrower channel spacing than the proposed scheme already.

Associate Professor, Dept. of Nursing, College of Medicine Yanbian Univ 5)School-nurse, Ewha Womans Univ. High School Purpose: This study examined the development and performance of the school health promotion policy guideline that is applicable to Korean school health. Methods: 1. The WHO's guideline was translated into Korean and modified by school health experts 2. A questionnaire was conducted to assess the performance of school health policy on 207 nurses in elementary schools in Seoul and Cheonbuk. Result: The Korean version of the school health promotion policy guidelines were developed including 9 components and 36 checkpoints. Compared to that of WHO, the component 'school nursing teacher' was added and three components were eliminated: 'equitable access to school resources', 'control of helminth', and 'sun protection policy'. The performance degree of first-aid, closure of school in a calamity, and control of HIV/AIDS was very low. The performance degree of a healthy diet, and regular physical examination was quite high. This study was the first that developed the school health promotion policy guideline and examined the performance. Further research is needed to validate the guidelines developed by this study.

1977年 7月 11日부터 9月 8日까지 60日동안 殼長 4∼6㎝(A群) 및 6∼8㎝(B群)의 소라에 4種의 餌料 (감태, E. cava; 모자반, Sargassum sp. ; 파래, U. pertusa; 갈라가라, G. falcata)를 投餌하여 餌料 價値를 實驗한 結果는 다음과 같다. 1. 餌料의 日間 攝餌率은 混合 餌料(2.10∼2.49%)가 가장 높았고 單一餌料로는 파래(1.57∼1.66%)가 높았다. 2. 混合 餌料 中 嗜好度는 파래, 모자반, 감태, 갈라가라의 順이였다. 3. 月間 殼幅 增加率이 제일 높은 餌料는 감태(1.13∼5.09%)였고 月間 增重率이 제일 높은 餌料는 混合 餌料(3.54∼5.26%)였으며 餌料를 供給하지 않은 對照區는 1.44∼2.11%의 減重率을 나타냈다. 또한 殼幅 增加率 및 增重率이 낮은 餌料는 모자반이였다. 4. 餌料 轉換效率의 크기는 混合 餌料, 파래, 감태, 갈라가라, 모자반의 順 이였다. 5. 增肉係數가 가장 낮은 餌料는 混合 餌料(12.44∼21.67)였고 가장 높은 것은 모자반(38.71∼47.56)이였다. 6. 殼長이 작은 A群이 殼長이 큰 B群보다 餌料效率이 높았다. A food value for the topshell, Turbo cornutus SOLANDER, fed four marine algage, Ecklonia cava, Sargassum sp., Ulva pertusa, Galaxaura falcata, was estimated at the Marine Biological Station, Jeju University, from July 11st, 1977 to September 8th, 1977. The experiment was carried out with two group of shell length 4∼6㎝ (A group ) and 6∼8㎝ (Bgroup). The highest valus of daily feeding rate was obtained in mixed feed (2.10∼2.49%) and those of alone feed was U. pertusa (1.57∼1.66% ). When a mixed feed was given, U. pertusa was superior in selectivity of feed (41.21∼50.46% ) and G. falcata was inferior (14.00∼14.07%). The highest value in monthly increase rate of shell width was obtained in E. cava (1.13∼5.09%), in monthly increase rate of total weight was mixed feed (3.54∼5.26%), and none feeding was represented 1.44∼2.11% of decrease rate in total weight. The efficiency of food conversion of mixed feed was superior (4.62∼8.04%) to the other feeds, and Sargassum sp. was inferior (2.10∼2.58%). The most lowest value of food coefficient was obtained in mixed feed (12.44∼21.67) and the highest value of that in Sargassum sp. (38 71∼47.56). The food effects of A group, shell length of 4~6㎝, was better than B group, shell length of 6∼8㎝.

Studies on the growth of topshell which had tagging liberated and ecological survey were taken from the three culturing topshell forms of the Seogwipo coast form June to December, 1977. Three culturing topshell farms are Supseom, Bomkri and Beophwanri coat. The culturing topahell farms are shallow with the mean depth 5∼8m, and vertical changes of water temperature and specific gravity in each arears were not appeared. The water temperaure of Supseom area was lower than the other areas. The compositions of submarine geological type in Supseom, Bomokri and Beophwanri area were B (Hole type) and C (crevice type) type, A (Rock type) type, and C and D (Sand type) type respectively. The Current speeds of each culturing farm area were in the range of 1∼20㎝/sec, and the current of Beophwanri culturing farm area was slower than the other areas. The absorption coefficient of Seogwipo coastal water in the range of 0.218~0.329 and the mean was 0.283. Fifty species of marine algae were identified. Major algal group of each culturing farms were Sargassum sp.,Ecklonia cava, Chladophora sp., calcareous algae. Particularly, Beophwanri culturing farm was abundant in Saragassum sp. Of the three culturing topshell farms increment in growth of topshell were showed rapid growth from June to October and noted that increment in growth of Bomokri was the highest. During the tagging liberated period, the number of spines on newly formed parts of shell was in the range of 0∼5 spines. The creeping distance was 5∼25m in each culturing topshell in all.

Objective: The purpose of this study was to examine factors influencing stress coping behaviors of elementary students in Korea. Methods: This study used a descriptive comparative survey design. A total of 1,161 elementary students voluntarily participated in the study from 10 schools at three regional levels (large and medium-sized cities, and rural towns). Coping behaviors were measured by the modified Ways of Coping Checklist. The data were analyzed using descriptive statistics, t-test, ANOVA, and multiple regression. Results: The most commonly used stress coping behavior reported by the participants was mystic coping, followed by positive coping, and negative coping. Students living in the large city and female students tended to use more coping behaviors than students living in the medium-sized city or rural towns and male students, respectively. Conclusions: Elementary students who are males, dissatisfied with their lives, or living in large cities or rural towns tended to be at risk for poor coping. There were differences in factors influencing coping behaviors by type of coping behaviors. An approach to building a successful coping behavior that is specifically tailored to the gender subsets of population and region-specific social and physical environment is recommended.

철재형 이안제 설계기법 연구 III. 투과성 철재형 이안제 후면에서의 해저면 변화

이정렬,권혁민,이주용 한국방재학회 2011 한국방재학회논문집 Vol.11 No.6

In order to solve various problems associated with gravity-type breakwaters, the permeable breakwaters are recently taken into account as an alternative tool to control wave heights to an acceptable level. In particular, they are favored from the point of view of coastal environment, since they do not in general partition the natural sea. In this study, therefore, we present a morphodynamic model applied to scattering wave fields. The numerical solutions are compared with experimental data on wave profiles and morphological change rates under a surface-piercing breakwater system. Our numerical study involves several modules: 1) nonlinear wave dynamics analyzed by a plane-wave approximation, 2) suspended sediment transport combined with sediment erosion-deposition model, and 3) concurrent morphological changes. Scattering waves are solved by using a plane wave method without inclusion of evanescent modes.
