  • This study suggests an approach for determining fleet size for LTL (less -than-truckload) transportation with dynamic demand for on-time supply of the parts between the assembly line in an automobile company and its part suppliers in Korea. The vehicles operated by the transportation trucking companies in Korea in general can be classified into three types depending on the ways how their expenses occur; company -owned truck, mandated truck which is owned by outsider who entrusts the company with its operation, and rented truck (outsourcing) . With the forecasted monthly production data a year, a heuristic algorithm is developed to determine the number of company-owned trucks, mandated trucks, and rented trucks in order to minimize the expected annual operating cost, which is based on the solution technologies used in the aggregate production planning and vehicle routing problem. Finally the algorithm is tested for the problem how the trucking company transports parts for the automobile company.

  • This study explored the differences in gender, developmental period and parents in terms of parenting, the cross-sectional and longitudinal relationships in parenting by gender, and the cross-sectional and longitudinal relationships between participant roles in bullying situations and parenting by gender. The subjects were 498 4-5th grade children and the instruments utilized in this study were the Parental Bonding Instrument (Bowers, Smith, & Binney, 1994) and the Participant Roles Scale (Sutton & Smith, 1999). The subjects were contacted again one year after the first contact. Results showed that the relationships between parents were longitudinally quite stable. Girls whose fathers had higher levels of accurate monitoring were more likely to be defenders cross-sectionally. Girls whose parents had more accurate monitoring were less likely to be victims longitudinally. The results underscore the importance of examining both gender and participant roles in bullying situations.

  • This study explored gender differences in social status, acceptance/rejection, perceived popularity, social emotions, avoidance and anxiety by participant roles in bullying situations. Subjects were 215 6th grade children. Instruments were the Participant Roles (Sutton & Smith, 1999), Peer Nomination (Coie & Dodge, 1983 Cillessen & Mayeux, 2004), Social Avoidance and Social Anxiety (Franke & Hymel, 1984) scales. Results showed that more boys than girls were in pro-bullying participant role groups; more girls than boys were in outsider groups. Boy pro-bullies were high in social rejection. Boy defenders were high in popularity and low in social avoidance. Boy outsiders had high social anxiety. Girl victims had low social status, low social acceptance and lowest perceived popularity; they were high in social avoidance and social rejection.

  • This paper examines the conventional notion of natural beauty and its legacy on the aesthetic experience of nature and landscape architecture in terms of critical perspective. We can take its clue for discussion from the our routine convention of experiencing natural beauty from the picture-like nature. We often equate natural beauty with superficial representations of nature shown in pictures. However, it is no more than a by-stander's nature seen purely through the eyes of the outsider. Problems of the picture-like nature can be summarized as the contemplative and visual-oriented aesthetic experience of landscape, which has had its influence not only on the ways of seeing the natural beauty but also on the ways of making it. The tradition of the picture-like nature has been transplanted into the real world through the practice of landscape architecture. It has been mass-producing superficial beauty of nature, focused on visual form. Landscape architecture in such a form is just a static means of decoration devoid of meaning and content.

  • In People usually think that smart materials and smart structures have not been developed until recent years. But those kinds of sensors have already been used for sensing damage in a variety of materials and structures. Two typical examples are piezoelectric materials (e.g., PZT) and electric strain gauges. Load cell is an example that utilizes the piezoelectric property to measure the change in physical quantities occurred by applied loads, while strain gauges are used to measure the deformation of compressive and tension members. The feasibility of using smart materials is realized for a monitoring technology when those sensors are used to monitor damages at inside or outsider of the structures. In this study, a fundamental study on the development of self diagnostic smart concrete using PZT, and unsaturated polyester electric resistance sensor.

  • The purpose of this study is to analyze the modelling behavior of public type quasi-government sector CEO. The results of the study on the 100 CEO is as followes as: 1) Such behavior as pointed by government is more frequently practiced by CEO of the quasi-government sector. 2) The general level of model ling behavior by CEO doesn't meet the expectations of the outsider in spite of the many effort of the CEO, 3) Effective practice of the modelling behavior is not performed because of the unsufficient knowledge about the modelling behavior of the CEO. Lastly, the summary and implications of this study is followed.

  • 본 논문은 국지적 상호작용 하에서 행위자들간에 특성의 차이에 근거한 구별짓기가 협조적 행위의 진화에 미치는 영향을 분석한다. 이 논문에서는 이러한 구별짓기의 성향이 왜, 그리고 어떤 메커니즘을 통해서 진화해나가는지를 보이고자 시도할 것이다. 아울러 구별짓기 성향과 함께 내부인과 외부인을 향한 행동을 다르게 함으로써 어떻게 내부인에 대한 이타적 협조행동을 발생시키는지, 더 나아가 구별짓기의 근거가 되는 행위자들의 여러 특성들(생물학적 혹은 문화적)은 어떻게 변화해 나가고 이들 특성의 변화가 구별짓기와 협조적 행동에 어떤 효과를 가져오는지를 살펴보고자 한다. 더 나아가 본 논문에서는 구별짓기가 협조적 행위의 진화에 영향을 미치는 과정을 장/단기로 구분함으로써 구별짓기의 효과를 보다 명확히 규명하고자 한다.

  • Recently, climate change have increased consumption of building heating and cooling energy. Therefore, various actions to reduce greenhouse gas and energy consumption have been prepared by world developed countries. The energy consumption by buildings approximately reaches 25% of total korea energy consumption. The greatest part in the buildings of the energy consumption is building facade. Especially the outer covering of the building has been made of concrete more than 70%. But a few research projects on concrete comprising more than 70% of outsider of buildings has been tried. This research is structural insulation concrete what improved insulation performance using Micro Form Admixture and Calcined Diatomite Powder and Lightweight Aggregate.

  • The purpose of the present study was to identify variables for predicting types of outsiders and possible mitigating factors in bullying situations. Participants were 344 $5^{th}$, $6^{th}$ and $7^{th}$ grade students(159 boys and 185 girls). Involvement of outsiders in bullying was examined by proportion. Major findings were that; (1) Over half of the sample(65.4%) were involved in bullying by either actively reinforcing(bully-followers; 6.4%) or passively observing(bystanders; 59.0%); 34.6% were defenders of victims. (2) Multiple discriminant analysis yielded a function of 3 variables(empathy, risk burden, and prosocial moral reasoning) that was effective in classifying bully-followers, bystanders, and victim-defenders. Empathy and prosocial moral reasoning predicted victim-defenders and risk burden predicted bully-followers and bystanders.

  • Recently, it is certain that the increase of heating and cooling energy consumption by radical change in climate condition has caused serious problems related to environmental and energy concerns associated with increase of fossil fuel usage and carbon dioxide production as well as global warming. So, various actions to reduce greenhouse gas exhaustion and energy consumption have been prepared by world developed countries. The energy consumption by buildings approximately reaches 25% of total korea energy consumption. The greatest part in the buildings of the energy consumption is building facade. but a few research projects on concrete comprising more than 70% of outsider of buildings has been tried.
