Analysis of Stem Wave due to Long Breakwaters at the Entrance Channel

권성민,문승효,이상헌,유재웅,이중우 한국항해항만학회 2017 한국항해항만학회지 Vol.41 No.5

Recently, a new port reserves deep water depth for safe navigation and mooring, following the trend of larger ship building. Larger port facilities include long and huge breakwaters, and mainly adopt vertical type considering low construction cost. A vertical breakwater creates stem waves combining inclined incident waves and reflected waves, and this causes maneuvering difficulty to the passing vessels, and erosion of shoreline with additional damages to berthing facilities. Thus, in this study, the researchers have investigated the response of stem waves at the vertical breakwater near the entrance channel and applied numerical models, which are commonly used for the analysis of wave response at the harbor design. The basic equation composing models here adopted both the linear parabolic approximation adding the nonlinear dispersion relationship and nonlinear parabolic approximation adding a linear dispersion relationship. To analyze the applicability of both models, the research compared the numerical results with the existing hydraulic model results. The gap of serial breakwaters and aligned angles caused more complicated stem wave generation and secondary stem wave was found through the breakwater gap. Those analyzed results should be applied to ship handling simulation studies at the approaching channels, along with the mooring test.

Characteristics of charcoals manufactured in each temperature as 400, 600 800, 1,000 and 1,200oC were examined. Sapwood and heartwood of Quercus variabilis that one of major species in charcoal materials were used for this experiment. Charcoal density was decreased highly 38-60% compared with wood density and density of sapwood was slightly decreased but heartwood was not changed with increasing carbonization temperature increase. Weight loss of sapwood and heartwood charcoal increased as carbonization temperature increases, and there is no difference between sapwood and heartwood charcoal. Refining degree of sapwood and heartwood charcoal was zero in charring over 800oC. Moisture and ash of sapwood and heartwood charcoal in each carbonization temperature were not differed between sapwood and heartwood. Volatile of sapwood charcoal was slightly higher than that of heartwood, and decreased as carbonization temperature increases. As the carbonization temperature increased, fixed carbon of sapwood and heartwood charcoal increased. Calorific values of charcoal prepared at 600oC were 7,200-7,300 cal/g and then decreased slightly as carbonization temperature increased.

권성민,김이영,최윤희 한국공공사회학회 2019 공공사회연구 Vol.9 No.1

본 연구는 유아교육기관에 근무하고 있는 유아교사의 어떤 변인들이 삶의 만족도에 영향을 미치는지에 대한 탐색을 시도한 연구이다. 이를 위해 유아교육기관에 근무하고 있는 교사 318명을 대상으로 삶의 만족도에 영향을 미치는 변인들인 직무소진, 사회지지, 유아교사의 인생관, 임파워먼트로 범주화하여 이들 변인이 유아교사의 삶의 만족도에 미치는 영향을 분석하였다. 첫째, 삶의 만족도에 영향을 미치는 직접 요인으로는 직무소진, 사회지지, 인생관 및 임파워먼트로 나타났다. 둘째, 직무소진은 인생관을 매개로 하여 삶의 만족도에 간접적 영향을 미치는 것으로 나타났으며, 사회지지는 인생관과 임파워먼트를 매개하여 삶의 만족도에 간접적인 영향을 미치는 것으로 나타났다. 본 연구결과를 종합하면 유아 교사의 삶의 만족도에 직무소진, 사회지지, 인생관, 임파워먼트는 직접적인 영향을 미치고, 직무소진은 인생관을 매개로 하여 삶의 만족도에, 사회지지는 인생관과 임파워먼트를 매개하여 삶의 만족도에 간접적 영향을 미치는 것으로 나타났다. 본 연구의 결과 유아교사의 삶의 만족도를 높이기 위해서는 직무소진의 감소, 사회지지 및 긍정적인 인생관과 임파워먼트의 증진을 위한 프로그램 개발 및 개입이 필요함을 시사한다. This study is to investigate what kinds of factors affect satisfaction with life of early childhood teachers who work in preschool educational institutions. For this purpose, factors affecting satisfaction with life were categorized to burnout, social supports, life stances of early childhood teachers, and empowerment, and influence of these factors on satisfaction with life were analyzed for three hundred eighteen female teachers who work in preschool education institutions. As a result of the analysis, first, we found that factors directly affecting satisfaction with life are burnout, social supports, life stances, and empowerment. Second, the burnout indirectly affects satisfaction with life via life stances, and the social support indirectly affects satisfaction with life via life stances and empowerment. Shortly to say, the burnout, social supports, life stances, and empowerment directly affect satisfaction with life of early childhood teachers. The burnout indirectly affects satisfaction with life via life stances, and the social support affects satisfaction with life via life stances and empowerment. This result shows that, in order to improve satisfaction with life of early childhood teachers, it is necessary to reduce burnout and develop a program or action for improving social supports, positive life stances, and empowerment.

Density, annual ring width, latewood percentage and compressive properties of Pinus koraiensis and Larix kaempferi grown in Research Forest of Kangwon National University were measured and their radial variations were investigated. Density(Wa/Va) of Pinus koraiensis and Larix kaempferi was 0.48g/cm² and 0.88g/cm², respectively. Density of both species was slightly lower at pith area, increased gradually with cambial age up to about 15 years and then became constant. Annual ring width of both species was 3.43㎜ and 2.83㎜, respectively. Annual ring width of both species was irregular at pith area but regular after about 20 years. Latewood percentage of both species was 30% and 47%, respectively. Latewood percentage of Pinus koraiensis and Larix kaempferi increased with cambial age up to 14 years and 10 years, respectively and then became constant. Compressive strength, proportional limit and Young's modulus parallel to the grain of Pinus koraiensis were 330 kgf/cm², 270 kgf/cm² and 9.2×10³ kgf/cm², and those of Larix kaempferi were 600 kgf/cm², 550 kgf/cm² and 20×10³ kgf/cm², respectively. Shearing strength in radial direction of Pinus koraiensis and Larix kaempferi was 51 kgf/cm² and 69 kgf/cm², and that of tangential direction was 56 kgf/cm² and 86 kgf/cm², respectively. In this study, compressive and shearing properties of both species did not show any significant differences between juvenile wood and adult wood. Both species showed significant differences in the measured values.

The purpose of this study is to research preschool teachers’ understanding of the Saemaul Undong, recognition of Saemaul spirit practice in the field of early childhood education and provide basic data to practice Saemaul spirit education suitable for infancy. For this purpose, questionnaires were distributed to 254 preschool teachers in several cities of South Korea to find out the levels of understanding Saemaul Undong and how much they feel the necessity of education relating to practice Saemaul spirit in the early childhood education. According to the results of the questionnaire, it revealed that first, 68% of the respondents know the past Saemaul Undong and recognize it as a movement positively contributed to national growth. Second, 82.3% of the respondents do not know the recent Saemaul Undong (i.e., Second Saemaul Undong). However, they consented that it is necessary to uphold and develop Saemaul spirits. In addition, in order for spirits or values to be inherited through the second Saemaul Undong, cooperation, sharing and caring are ranked in order of important values. In particular, cooperation and caring are ranked as the most important Saemaul spirits in the early childhood education.Third, it was revealed that 74.5% of the responding preschool teachers think practicing and educating Saemaul pirits are necessary in the early childhood education fields, because it can be helpful for children to have good human nature, lifestyle habit, and learn how to contribute to a community life. 본 연구는 교육현장에서의 글로벌새마을정신 실천에 대한 유아교사들의 인식을 알아보기 위해 진행되었다. 유아교사 254명을 대상으로 새마을운동에 대한 기본적 인 이해를 알아보고, 유아기 교육에 있어서 글로벌새마을정신으로 거론되는 근면, 자조, 협동, 배려, 나눔, 봉사, 창조, 변화, 도전과 같은 요소의 중요성에 대한 유아교사 의 인식을 조사하였다. 연구결과, 응답자의 68%는 새마을운동에 대해서 알고 있었 으며, 새마을운동이 우리나라의 성장과 발전에 긍정적인 기여를 한 것으로 인식하였다. 응답자의 82.3%가 글로벌새마을운동에 대해서 잘 모르지만 세계화 시대를 살아 가는 오늘날 사회에서 새마을정신의 계승 및 발전은 필요하다고 하였다. 특히 유아기 교육에 있어서 중요한 정신은 협동과 배려라고 생각하였고, 응답자의 74.5%는 교육 현장에서 이와 같은 글로벌새마을정신의 실천과 교육이 필요하며, 그 이유는 올바른 인성 함양, 기본생활습관 형성, 공동체 생활 덕목 함양으로 나타났다.
