  • Japanese government has instituted and carried out Super-core Ports Policy to improve their operating efficiencies of international container ports from 2004. Despite of diverse institutional and administrative supports within this policy, this paper has assessed that they couldn't accomplished goals at the end of 2009 when the policy ended. In short, Japanese Super-core ports have explicitly lost the competitiveness for functioning as a hub-port in the East Asia region. We could find some defaults in the policy i.e. some limits of the private terminal operating units, inefficiencies in teaming between ports within Super-core port, lacking with system for collecting cargoes. In 2010, Japan is going to reinforce International Strategic Container Port Policy following Super-core Ports Policy. With this policy, they ought to prepare for the last leap on the basis of selection and concentration rules in international port. This new policy is particularly focused on recapturing their T/S cargo via Busan port. Regarding these changes, Busan port needs to prepare counter measurements for preserving Japanese T/S cargo firmly.

  • Since 1996, Korean National Police Agency has been promoting a project for installation of Automated Speed Enforcement (ASE) system aiming at reduction of accidents. The number has increased to 5,348 stations throughout country as of December 2012. Recently, the Section Speed Enforcement Systems have been installed at many sites to produce a general effect well beyond the localised effect at overt fixed camera sites. In this study aims, we have analyzed the effects of the Section Speed Enforcement System at the Misiryeong tunnel section. We have found that there were a statistically significant 21.4%~31.% reduction of the average speed and 45.9% reduction in a number of traffic accidents per month. Accordingly, the study indicates that the Section Speed Enforcement Systems at Misiryeong tunnel section has effective to produce road safety.

  • The present study was conducted with aim for establishing the framework of integrated veteran policy for unified Korea through the analysis of the North Korea's veteran policy. For the purpose, this study reviewed the legal system and implementation process concerning the North Korea's veteran policy and analyzed the establishment of fundamental framework of unification and the implications from the North Korea's veteran policy for unified Korea. The review of the North Korea's veteran policy covered the beginning of the North Korea's veteran policy to the present. Based on the findings of the review, this study revealed the necessity of re-establishing the principle of veteran policy in preparation for unification and proposed a plan for unified veteran policy. The results from this study are expected to be a meaningful milestone to unified veteran policy after unification. It is reasonably expected that there will remain considerable differences and conflicting factors, which could block the path to national integration, between two countries and their peoples after unification. Therefore, it is more important to make a thorough preparation and form social consensus than any other. In this respect, national policy for veterans should go back to basics and be reviewed to be ready for unification. Although different in time, the North Korea's veteran policy was and is the base of the nation's system and source engine for development every period. Re-designing the principle of veteran policy should reflect both symbols of the unified nation and the national identity, but also of socially integrated spirit. Therefore, it must include the spirit of patriotism and awareness of national security. Furthermore, as for the integration of veteran policies for unification, it is especially important for two countries to possess and share common historical consciousness. The unified veteran policy should be integrated on this base.

  • SSI instruction can be an effective tool to promote key competencies for future citizens. Our assumption of the study is that applying the concept of collective intelligence in the context of SSI learning would facilitate the learning. Thus, we designed and implemented Collective Intelligence-based SSI instruction over almost a year and observed the effects of the instruction on enhancing students' collaboration, information management, critical thinking, and communication skills. Twenty 9th grade students enrolled in a science-gifted program voluntarily participated. Data was collected by administering a questionnaire to examine the skills before, in the middle of, and after the instruction, and by conducting classroom observations and focus student group interviews. The results indicated some degree of improvement in their targeted skills. First, they experienced the expansion of their thoughts by actively sharing information and ideas using the web platform. Second, they became more flexible and open to different points of views in order to accomplish a common goal. Third, they appreciated having independent time and space to explore their own positions on the issues and to search necessary information, and believed that the process encouraged them to more pro-actively participate and communicate in the group debates. Lastly, they positively perceived the values that collaboration with diverse group members could produce.

  • A feeding experiment for 160 days was conducted to evaluate effects of dietary soybean meal (SBM) on the apparent digestibility, ammonia excretion and body composition of rainbow trout (Oncorhynchus mykiss). Seven diets containing 0\~70%0\~70% SBM were formulated based on iso-nitrogenous and iso-caloric basis of 44%44% crude protein and approximately 4,200 Kcal/kg of gross energy. To evaluate the nutritional utilization of the SBM diets at the end of 60 and 120-day rearing with test diets, digestion rates of protein and lipid of SBM diets were measured. Fish fed the diets containing above 46%46% SBM showed higher apparent digestibility for protein, but lower for lipid than did fish fed the control diet in both trials. Protein and fat contents in the carcass were similar for all experimental fish, except for fish fed 58%58% and 70%70% SBM which showed lower fat content than the others, but composition of fatty acid and amino acids were not affected by dietary SBM levels. Gill and urinary post-prandial ammonia (NH3NNH3N) excretions were measured at 12 and 24 hours after single feeding of the experimental diets. Excretions of NH3NNH3N measured after 24 hours were almost 1 times higher than those measured after 12 hours. Total excretion fer the 24 hours by fish fed 70%70% SBM was 15%15% higher than that of fish fed the control diet. Results of present study may suggest that the rainbow trout which were fed above 3434 of SBM diet showed a decrease gradually in lipid bioavailability compared to the control group.

  • The objective of the present study was to develop a thanksgiving program for high grade elementary students' anger control and analyze its effects. For this purpose, we set research question 'Does a thanksgiving program have an effect on children's anger control?' and applied a 10 session thanksgiving program to 30 fifth graders in a class, for which the present research was the class teacher, at K Elementary School. A thanksgiving program is a group counseling program that induces the participants to think what a thankful mind is, to find things to thank for around, and to express thanks through specific actions. This study was conducted in a way different from previous research that obtains data from a control group who do not participate in the program and an experimental group who participate in the program In this study, the effect of the program was analyzed according to the level of participation in the experiment. For this, the children were divided into two groups using coupons after the application of the program, and the effect of the thanksgiving program was examined through comparative analysis between the groups and within each group using data obtained from a pretest and a posttest with an anger scale. According to the results, significant changes caused by the positive effect of thanksgiving were observed in the five areas of anger, which are state anger, trait anger, anger repression, anger expression and anger control. That is, the thanksgiving program developed using thanks was found effective in elementary children's anger control. This conclusion is consistent with the reports by Rho Ji hye (2005), Kwon Sean jung et al. (2006), and Kim Dong hee (2008) that a thanksgiving program based on the emotion of thanks can control the emotion of anger.

  • The dynamic nature of mechanization and automation to improve productivity and safety within logistics centers, has necessitated various studies to support efficient and safe working conditions for workers. However, accidents in the loading dock occur frequently as workers and forklift trucks operate within the same space. This research introduces cargo batch loading and unloading systems, which enable increasing productivity and safety through the use of mechanization and automation in the loading dock. To assist efficient operation of this new system, four pieces of general-purpose equipment or three pieces of dedicated equipment are deemed to be essential. Moreover, the floor area of the loading dock is designed to accommodate 256.28m2256.28m2 and 207.00m2207.00m2 for the general-purpose and dedicated systems respectively, in addition to the space allocated for equipment and additional space. The design of the loading dock considers the area of the loading dock as well as the cargo batch loading and unloading systems. Economic analysis, such as NPV, IRR, and PBT, were conducted in addition to sensitivity analysis on key variables.

  • The purpose of this study is to investigate how elementary mathematics teachers use and implement a reform-oriented mathematics curriculum material, Everyday Mathematics, and to examine what features the curriculum material has. Eight elementary mathematics teachers in the United States participated in the study. Data sources consist of teacher classroom observation write-ups, interviews, and the curriculum material. The results from the analysis of the curriculum material suggest that 80 percent of the tasks are at the high-level in terms of cognitive demand and 26 percent of tasks are identified as transparent. The results also show that the teachers appeared to adapt the curriculum material and partially take suggestions or activities out of the curriculum material in enacting them in their mathematics classrooms. The analysis of enacted tasks suggests that the levels of cognitive demand were shifted from high-level to low-level; 27 percent of the high-level tasks in the curriculum material were maintained at the high-level as enacted in the mathematics classrooms. The level of cognitive demand shifted in many cases; shifts from high-level to low-level occurred. This contributes to the curriculum material not being transparent to teachers.

  • Pythium blight caused by Pythium spp. is one of major diseases in putting green of golf course. In this study, microorganisms which are anatgonistic to Pythium aphanidermatum, a pathogen of pythium blight, were selected primary through in vitro tests, dual culture method and triple layer agar diffusion method. In vivo test against pythium blight were conducted to select the best candidate biocontrol microorganism by pot experiment in a plastic house. Bacillus subtilis GB-0365 was finally selected as a biocontrol agent against pythium blight. Relative Performance Indies(RPI) was used as a criterion of selecting potential biocontrol agent. B. subtilis GB-0365 showed resistance to major synthetic agrochemicals used in golf course. Alternative application of synthetic agrochemicals and B. subtilis GB-0365 was most effective to successfully contol pythium blight. B. subtilis GB-0365 suppressed the development of pythium bight of bentgrass by 56.4% as compared to non-treated control and its disease control efficacy was 60.9% of a synthetic fungicide Oxapro(WP) efficacy. B. subtilis GB-0365 has a potential to be a biocontrol agent for control of pythium blight.

  • 북한(北韓)의 경제개발전략(經濟開發戰略)의 제특징(諸特徵)은 저렴한 농산물가격(農産物價格)에 의한 농업부분(農業部分)에서의 잉여(剩餘), 저임금(低賃金)에 의한 도시노동자(都市勞動者)들로부터의 잉여(剩餘)를 가지고 경제발전(經濟發展)을 이룩하는 것이라 요약할 수 있다. 농민(農民), 도시노동자(都市勞動者) 양측(兩測)을 희생시키면서 유지되어 온 이러한 성장구조(成長構造)는 원래 같으면 저농산물가격(低農産物價格)저임금(低賃金)축적자금확대(蓄積資金擴大)재투자(再投資)생산량증가(生産量增加)소비수준 (消費水準) 증가(增加)로 점진적으로 발전해야만 하는 것이다. 하지만 이러한 성장전략(成長戰略)은 처음부터 철저히 부정되어 왔다. 먼저 농촌부분(農村部分)부터 보면 농촌협동조합(農村協同組合)에서의 소유제도(所有制度), 분배제도(分配制度)의 문제(問題)로 인해 농민(農民)의 근로의욕(勤勞意欲)이 크게 상실되었고 그 결과(結果) 농업생산(農業生産)은 저하되었다. 한편 도시부분(都市部分)에서는 인민(人民)들의 저소비(低消費)의 결과(結果)로 축적된 자금(資金)이 군사부분(軍事部分)에 집중적으로 투자됨으로 인해 그 투자효과(投資效果)가 제 구실을 못하게 되었다. 뿐만 아니라 자급자족지향형(自給自足指向型)의 중공업화(重工業化)는 중공업(重工業)과 관련산업(關聯産業) 상호간(相互間)의 수요(需要)만을 충족시켜 왔다. 그 외에 기업(企業)이 국가(國家)의 지령(指令)에 의해서만 움직이는 국영기업관리체제(國營企業管理體制)의 비효율성(非效率性)도 지금의 북한경제(北韓經濟)를 침체(沈滯)의 늪에서 헤어나지 못하게 하는 주요(主要)한 요인(要因)으로 작용했다. 농업생산(農業生産)의 정체(停滯), 중공업(重工業)을 위한 중공업정책(重工業政策)이라고 하는 왜곡된 투자구조(投資構造), 기업관리체제(企業管理體制)의 비효율성(非效率性)은 북한(北韓)의 계획경제순환구조(計劃經濟循環構造)를 기본(基本)부터 뒤흔들기 시작하면서, 급기야 1980년대 후반부터는 순환구조(循環構造) 그 자체(自體)를 마비시키는 사태(事態)로까지 발전했다. 순환구조(循環構造)의 마비(痲痺)라고 하는 심각한 경제난(經濟難)을 타개하기 위해 북한(北韓)은 나진(羅津) 선봉(先鋒) 자유경제무역지대(自由經濟貿易地帶)를 설치(設置)하고 새로운 자금축적원(資金蓄積源)으로서 외국인직접투자(外國人直接投資)를 유치하는 개방정책(開放政策)을 추진하여 왔다. 하지만 북한(北韓)의 경제(經濟) 순환구조(循環構造)의 마비(痲痺)를 풀 수 있는 근본적(根本的)인 해법(解法)은 어디까지나 그 발단(發端)인 농촌(農村)의 경제체제개혁(經濟體制改革), 농(農) 경공업(輕工業)을 위한 중공업(重工業), 국영기업(國營企業)의 개혁(改革) 등을 과감히 실시하는 것이다. 왜냐하면 해외직접투자(海外直接投資)라는 새로운 자금축적원(資金蓄積源)은 어디까지나 지금의 악순환구조(惡循環構造)를 임시적(臨時的)으로 정지시켜 주는 보완적(補完的)인 조치(措置)에 불과하기 때문이다.
