This study used the Q-method to derive the structure of subjective opinions and perceptions of university students about the behavior of food delivery agency service provided by staff not directly employed in restaurants. For this purpose, the Q factor analysis was performed using the PC QUANL program for the Q-sort, which consists of a statement card, a P-sample, and a classification process. The results were classified into three types. The factor names were set as the first type (N = 7): efficiency seeking type, the second type (N = 19): benefit seeking type, and the third type [(N = 6): cost-effectiveness seeking type. The characteristics of each type are Type 1:Types that recognize aspects that are efficient for both consumers and restaurants, Type 2: Types of recognizing aspects of being benefited from speed, convenience and benefit, Type 3: Although it contributes to labor cost savings, it appears to recognize price and quality aspects in the initial market, which is burdened by consumers. The purpose of this study is to derive the problems of food delivery agency service business according to the three types and to provide strategic implications for the development direction and improvement plan.

The increase of input resources, such as labor and equipment, in a construction project causes workspace interference between activities and it influences on the productivity and quality of construction activities. To solve this problem, many studies related to the workspace interference have been performed, however they verified the workspace concerning with only the geometric location of activities or generated the shape of workspace by a whole object concept not separated units of detailed operations. It is difficult for project manager to reasonably analyze the workspace conflict, because the size of workspace cannot reflect the characteristics of an activity and input time of a resource. This paper presents a methodology that can generate three-dimensional models in order to optimize the workspace shape and size by considering with the characteristics of each activity and input time of each resource. The suggested method can be used for the active BIM system that optimizes the workspace conflict without additional construction duration and for the searching algorithm of optimized moving path for construction equipment.

This paper analyzed productivity of quay cranes on container terminal that have perpendicular yard layout block. In most existing container terminals, quay cranes of single trolley type are used to loading and unloading containers, but quay crane productivity of these type has many limitation about large size containership. For these reasons, recently quay cranes of various type that mn improve productivity are developed and as the representative example, dual trolley, double trolley, supertainer are developing. These cranes are realized that very high productivity bemuse their cycle time is short more than existent single trolley quay crane. Therefore, we analyzed productivity of these cranes that are realized by next generation crane alternatives and as result qf this research, mechaniml productivity by cycle time and net productivity by simulation were measured.

Service part has the attribute causing a difficulty of the systematic management like a kind of diversity, uncertainty of demand, high request for quick response against general complete product. Especially, order picking is recognized as the most important work in the warehouse of the parts since inbound cycle of the service part long but outbound cycle is relatively short. But, increasing work efficiency in the warehouse has a limitation that cycle, frequency and quantity for the outbound request depend on the inherent features of the part. Through this research, not only are the types of the parts classified with the various and specified data but also the method is presented that it minimizes (that) the whole distances of the order picking and store location about both inbound and outbound by developing the model of the demand prediction. Based on this study, I expect that all of the work efficiency and the space utilization will be improved without a change of the inbound and outbound quantity in the warehouse.

Submarine cable is the most important IT infrastructure for international communication across oceans. However, a cable fault rarely happens by ship's anchor, fishing gears, submarine earthquake, and so on, and we need to improve on repair time for the reducing expenses of cable repair ship as well as the stability of high-capacity submarine optical network. There are several kinds of cable faults such as Shunt fault, Cable cut, Open fault and Fiber break. When a fault is occurred, cable landing stations(CLS) have to analysis failure quickly and accurately to find the type and the location of a cable fault. During the repair period, CLS should swiftly perform the tests requested by cable repair ship. In order to make rapid progress on cable repair, CLS test technique is very important. So, in order to reduce the repair time, this paper is studying the CLS test techniques of locating a submarine cable fault and of checking the splicing point performed by cable repair ship.

Objective : This study aimed to identify the relationship between sensory processing and personality in college students by using five personality factors. Methods : The study was conducted between October and December 2022 with 149 college students majoring in health studies. Sensory processing was evaluated using the Adolescent/Adult Sensory Profile (AASP), and personality was evaluated using the International Personality Item Pool (IPIP). The data collected were analyzed by descriptive statistics, frequency analysis, and Pearson correlation analysis, and the Statistical Package for the Social Sciences (SPSS) was used. Results : Extraversion and agreeableness showed a significant correlation with all sensory processing types. Neuroticism showed a positive correlation with all types of sensory processing other than sensory seeking, while openness to experience showed a positive correlation with sensory seeking. Conscientiousness showed a negative correlation with low registration and sensory sensitivity type (p<.01). Conclusion : This study found a relationship between sensory processing type and personality type through an evaluation of five personality in college students. This information can be used to find solutions to various problems that college students.

This study aimed to examine the relationship between students' power types and the roles taken by students in school bullying situation. Four types of power relationship were identified by crossing two dimensions of power relationships among students, which are 'possibility of power acquisition,' and 'need for power acquision.' Salmivalli et al.'s(1996) six particpatants' roles taken by individual student were employed as possible roles for students in school bullying situations. Samples of 1822 cases were analyzed to test the relationships. Results showed that control type youth tend to be bullies, assistants of the bullies, or reinforcers of the bullies; both the followers of bullies and the recluse type youth tend to be victims. Surprisingly influential youth did not take any vivid roles in school bullying situations. Implications as well as suggestions were presented.
