The study skills, learning motivation. academic adjustments are the significant factors that positively influence the learning process of school learners. In this study, the study skills were measured by 7sub-skills of self-managements, listening and participating in class, task-solving, effectively reading, report writing, information processing, and test-taking Learning motivation were composed of academic self-efficacy and academic failure tolerance And academic adjustments were composed of single scale with 20 items. The purpose of this study were to examine relationships between these process variables and learning outcomes, to explore the relative importance and combined effects of these process variables(10 factors) to academic achievements, and to find the differences in the process variables by sex and academic achievements levels. For this study, 100 male students and 229 female students were purposively sampled in S University. Their GPA were also obtained from their instructors. The major findings in this study were as followings. First, the study skills, learning motivation, and academic adjustments were closely interrelated with the correlation of .53 - .72. The combined effects of study skills and learning motivation to academic-adjustments were 61 percent. Among the variance, the test-taking skill had 57 percent, and self-efficacy skill, task-solving skill, and effectively reading skill had 11 percent, 2 percent, and 1 percent respectively. Second, lower achiever showed more negative behavior and attitudes than normal and higher achiever in 9 factors of the learning process variables. Among these factors. task-solving skill were found to be most important factor through regression analysis. This factor explained 15 percent of variance of academic achievements. Third, the level that college students have utilized study skills in their school learning were 2.8 and the level of learning motivation were 2.5 on 4-point scale. The skill that the students used most frequently were task-solving(3.1 point). Female students showed more positive behavior than male students in the use of study skills. In learning motivation, male showed more positive attitudes. But there were no significant differences by sex in academic adjustment.

북한 붕괴시 다국적군 파병 가능성과 한국의 외교적 대응

One cannot think of any possible change in the international politics of East Asia without considering North Korea, which is surely a decisive variable determining stability and change in the regional security. This paper examines the regime crisis and possible alteration in the nature of North Korean regime. Therefore, a very starting point that this paper is concerned is possible collapse of North Korea and possibility of intervention by multinational forces, should any dramatic events occur. For the first part of the paper argues that, in forecasting North Korean collapse, the definition of collapse should be presented with more precise definition. When setting scenarios for the collapse of North Korea, its collapse scenario must be multidimensional rather than linear dimensional Not only the collapse of North Korea occurs due to a single factor but also it will not proceed in a single dimension. Distinguishing implosion and explosion tends to oversimplify and, moreover, ignore externality which accounts for foreign policies by surrounding states (the Us, Japan, Russia and China) toward North Korea. Considering externality implies that the Korean problem is influenced by the international community and especially North Koreas survival is much more determined by what types of foreign policy are exerted by the surrounding states in the region. The second part of the paper entails the actual scenarios of North Korea and examines possibilities of intervention by multi-national forces in the courses of the collapse. Collapse can be seen in the forms of socio-economic, political regime and system collapse. The socio-economic collapse entails the breakdown of food-rationing, surveillance and production systems. In it, the existing social stratification and class tension will be apparent. The collapse of political regime defines power struggles, military-coup and civil wars. The final phase of collapse is the demise of the system. Once the socio-economic and political foundation become obsolete, new fungible groups must come in to replace the old one. This is where the intervention of international community may be visible and gradual unification. may come into reality. Should North Korea collapse, the surrounding states (the Us, Japan, China and Russia) may intervene by claiming that their intervention is to secure the regional and international stability as well as their own national security. Each state may justify its decision based on prior-bilateral agreements that are formed either by North or by South Korea. The complex web of alliance pacts around the Korean peninsula may enable them to participate in the advent of the collapse. The US may intervene with the Time Phased Force Deployment under the Operation Plan 5027. The US may do so through its policy of engagement and enlargement. China, self-advocate to be a regional stabilizer, may intervene under the China-North Korea Pact, formed in 1961, which agrees to provide any necessary assistance, including military means, should any engaging party falls into invasion by other states. Japan can play its role under the new US-Japan New Guide Line which explicitly allows Japan to engage in the Non-combat Evacuation Operation (NEO) if any crisis occur in the region. As seen in the case of Somalia, Bosnia and East-Timor recently, the role of the United Nation may play decisively in implementing its peace keeping mission. The last part of the paper reviews the German experience, especially the foreign policies of the Kohl government in the phase of the German unification, which effectively dealt with and prevented any foreign intervention including the former Soviet Union. From this, the paper conclude with implications for the Korean foreign policy readiness: Korea should tighten its current alliance with the US and at the same time should be able to secure its unification initiatives independent of external influences. If not, Korea must at least minimize foreign intervention so as to maximize its interest and lead its national destiny as a unitary actor.

This paper reviewed the previous researches on the relation of learner's characteristics and academic achievement. Carroll(1963) and Bloom(1976) screened the critical variables of learner's related to school achievement. The learner-related variables suggested were the level of prerequisite learning, subject-specific aptitude, general intelligence, reading comprehension as the cognitive entry behavior of learner's, and subject-related and school-related affect, persistence in learning, academic self-concept as the affective entry behavior of learner's. Through the review of the researches related to school learning, we concluded that the level of prior learning of learner's was the most important factor in predicting school achievement, and creativity had as much strong effect as general intelligence on school learning. In addition to these variables, learner's cognitive style was significantly related to school achievement. The combined effect of learner's affective factors of academic self-concept, learning habits, and subject-related and school-related affects on school achievement was about 33%. Of the several variables of learner's affective characteristics, academic self-concept was found to be the strongest factor with the effect of 25% and above on school achievement.

A grease filter is used to remove grease generated from a cooking appliance in a kitchen. This numerical study has been conducted to investigate the particle collection characteristics of a grease filter having nominal flowrate of $100m^3$/h. The flow field and particle trajectories in the grease filter with a flow chamber were simulated by using the commercial code of STAR-CD. The air velocity and pressure distributions were discussed in detail. The pressure drop of a grease filter rapidly increases with increasing the air flowrate. The numerical values of the pressure drop are slightly lower than the experimental values when the air flowrates are 50, 75, and 100㎥/h. The particle collection efficiency of a grease filter increases with increasing the particle diameter, the particle density, and the air flowrate, which means that the inertial impaction is a dominant particle removal mechanism in a grease filter. The cut-off diameter of the tested grease filter representing 50-% collection efficiency is about 11.6<TEx>$\mu$m for water droplets at $100m^3$/h.

김기정 한국전기기술인협회 2001 電力技術人 Vol.230 No.10

음향공명 발생원인 가스가 들어있는 방전관내에 방전전류가 흐르면 전력에너지가 발생하여 열을 발생 시키고 이 열은 방전관내의 압력변화를 가져온다. 이 압력변화는 방전관내의 음향변화와 같다. 주기적인 압력변화가 내벽에 반사되어 정재파가 발생되는 현상이 방정관의 고유진동수이며 이 고유진동수와 전원주파수가 일치될 때 음향공명현상이 일어난다.

A grease filter is used to remove grease generated from a cooking appliance in a kitchen. Since the inertial impaction is a dominant particle removal mechanism of the grease filter, the performance of the filter is greatly affected by the geometry. This numerical study has been conducted to investigate the effect of geometry on the performance of grease filters for four models having nominal flowrate of 100 m$^3$/h. Four models were designed by changing the shape of impaction surface, the length of eyelid, and the number of eyelids of the grease filter. The flow field and particle trajectories in the grease filter with a flow chamber were simulated using the commercial code of STAR-CD. The difference of air velocity and pressure distributions among four models was discussed in detail. The collection efficiency curves and the pressure drops of four models were also compared. It was found that the grease filter model with flat top surfaces shows highest performance among four models, having high particle collection efficiency and relatively low pressure drop. The cutoff diameter of this model representing 50-% collection efficiency is about 7.1 ${\mu}{\textrm}{m}$ for water droplets at 100 m$^3$/h.
