This study examined the research trends of "Microplastic in food" with a scholar databaseusing the centrality analysis method. The data was based on research papers published from 2011 to 2020, sorted by "microplastic" and "food". The centrality analysis methodology(Degree centrality, Closeness centrality, Betweenness centrality) was applied, followed by a keyword-based frequency occurrence analysis. The results suggested that more than 30% of the total keywords were related to "marine" and "pollution". Therefore, research on the effects of microplastic pollution on the ecosystem had mainly been conducted. On the other hand, only 6% of the keywords were related to "toxicity" and "ingestion". Hence,the number of studies on microplastic exposure caused by bioaccumulation or food are still insufficient. These results can be used to provide directions for future research, as well as provide basic data for political decision-making on the environmental hazards of microplastic.

The fungicidal activities against resistance phytophthora blight (RPC; 95CC7303) and sensitive phytophthora blight (Phytopthora capsici) (SPC; 95CC7105) by new 2-alkoxyphenyl-3-phenylthioisoindoline-1-one derivatives (A & B) were studied using molecular holographic quantitative structure activity relationships (HQSAR) methodology. Based on the results, the statistical results of the two best HQSAR models, RI-B for RPC and SII-A for SPC exhibited the best predictability and fitness for the fungicidal activities based on the cross-validated value ($q^2=0.806{\sim}0.865$) and non cross-validated value ($r^2_{ncv.}=0.921{\sim}0.952$, respectively. The quality of the model for SPC was slightly than that of RPC. From the based graphical analyses of atomic contribution maps, it was confirmed that the novel selective character for fungicidal activities against RPC depends upon the 2-fluoro-4-chloro-5-alkoxyanilino group.

In this study, Q methodology was applied to investigate the subjective evaluation of department jumpers and characteristics of each type of recognition for college students. As a result of analyzing, they were classified into three types. Type 1 was recognized that the department jumper plays a role of giving a sense of belonging to the department and promoting the department. In addition, it was analyzed that wearing a department jumper would be cautious, but the activities were comfortable and people around me gave good evaluations and thought it had the effect of enhancing my confidence. In the case of type 2, the department jumper was satisfied because it was an easy-to-work and non-fashionable design, and was always worn when going to university. Type 3 was a type that gives a sense of belonging when wearing the department jumper, and that it was good for the department jumper to follow the fashion. It is thought that a department jumper with a good fit should be developed by reflecting the physical characteristics, showing the image or symbolism, so that the department jumper of college students can function as a uniform.

This paper describes a method of AAL(SSCOP) protocol conformance testing and its result analysis in ATM network. Terminal equipment(TE) that implements protocols for connecting ATM network shall be verified if appropriately implement by conformance testing. The protocol specifications and the testing methodology are recommended or standardized by international standardization organization(ITU-T, ISO, etc.). The ATM AAL (SSCOP) protocol which selected for describing conformance test procedure is standardized in ITU-T Q.2110 and ATM Forum UNI 3.1 which are same in contents. Also Testing standard like ATS for SSCOP is specified in ATM Forum 95-1459R2. Construction of conformance testing environment is necessary to coordinate in relations with standards, then testing must beexecuted at that environment and the results from the test system analyzed. For this, it is necessary to select any test case from standard for testing and to make ETS. The ETS is proted on the test system and conformance testing will execute on that system. Finally the result from the test system is to analyze. This conformance testing procedure is applicable to the same other test cases in SSCOP and protocols in any communcation networks.

Quality function deployment (QFD) is a widely adopted customer-oriented product development methodology by translating customer requirements (CRs) into technical attributes (TAs), and subsequently into parts characteristics, process plans, and manufacturing operations. A main activity in QFD planning process is the determination of the target levels of TAs of a product so as to achieve a high level of customer satisfaction using the data or information included in the houses of quality (HoQ). Gathering the information or data for a HoQ may involve various inputs in the form of linguistic data which are inherently vague, or human perception, judgement and evaluation for the information and data. This research focuses on how to deal with this kind of impreciseness in QFD optimization. In this paper, it is assumed as more realistic situation that the values of TAs are taken as discrete, which means each TA has a few alternatives, as well as the customer satisfaction level acquired by each alternative of TAs and related cost are determined based on subjective or imprecise information and/or data. To handle these imprecise information and/or data, an approach using some basic definitions of fuzzy sets and the signed distance method for ranking fuzzy numbers is proposed. An example of a washing machine under two-segment market is provided for illustrating the proposed approach, and in this example, the difference between the optimal solution from the fuzzy model and that from the crisp model is compared as well as the advantage of using the fuzzy model is drawn.

This study applied the Q methodology to analyze the subjective evaluation and recognition patterns of elderly women's clothing preferences. For the type 1, knitted materials and natural materials were preferred, and pastel colors were preferred. The type 2 preferred pants that cover the body shape, look young, and have good simple activity. The type 3 was a type in which the waist was treated with a rubber band, the clothes were comfortable to wear and the loose style was preferred. The type 4 was simple and prefers a style with a raised neck and no fasteners, and a clothes that was comfortable to wear. Type 5 was a type that prefers a style that looks important and colorful and youthful in design or color. In order to develop ZIGTECHnology apparel for older women, it is necessary to develop a design that can look aesthetically beautiful while covering the body shapes such as bending of the back and bending of the waist by reflecting the preferences of the older women. It is considered that it is necessary to develop clothing that takes into consideration movement functionality without obstacles to movements in consideration of changes in behavior and movement of hands.

With the rising popularity of food shows driven by the development of information and communication technologies, food-incorporated broadcasting programs based on various materials are produced in large numbers. This situation has raised a need for each program to examine viewers' preference factors for planning intentions in order to produce competitive programs. This study thus examined viewers' preference factors for food programs and planning intentions and discovered total three factors. The first factor places importance on practicality and entertainment and enjoys food and food programs as a means of resting. The second factor searches for specialized information and focuses on the essential meanings of food and the delivery of the right information. Finally, The third factor gets satisfaction from interactions with food programs and finds joy in storytelling and communication provided by broadcasting programs. These factors have different tendencies from one another, and the present study proposed a concept design for food broadcasting programs based on them.

The purpose of this study is to provide a basic data of clothing development which can improve the satisfaction of the body shape by examining the subjective evaluation and type characteristics of the old-old women themselves. Q methodology was used for the study of subjectivity. The types of the body shape of the old-old women were analyzed as five types: bent body with protruding abdomen, backward bent body with slender legs, inverted triangle, swollen cylinder, triangle. The bent body with protruding abdomen had a bent back and waist. They were recognized that the bust and shoulders were sagging and abdomen was protruding. The backward bent body with slender legs was the smallest of the five types with a BMI index and shoulders and bust were sagging. And knee and waist were bent and legs were thin. The inverted triangular shape showed the highest BMI index among the 5 types, indicating that it is obese. They thought that the upper body was developed and the lower body and legs were slender. The swollen cylinder shape was analyzed to be the smallest and the most fat body. The triangle shape had developed lower body and bent back and waist. It is considered that a design consideration is needed to cover the disadvantages of the body shape in consideration of not only wearing feeling but also aesthetic part when making clothes. By making ergonomic garments considering the characteristics of body shape, it can be expected to change the body shape due to the wearing of clothing that is not suitable for body shape and the effect on physical health in a positive direction.

This study was designed to find the characteristics and patterns in subjectivity of the perspectives on the coping strategies about practical stress in nursing student. Q-methodology was used as a research design and the research procedures were as follows. Q-sampling has been derived from the literature review and a questionnaire. Its credibility and validity were also tested by nursing professors. Total of 34 statements were selected. P-sampling has been drawn and 51 samples were selected. Based on 9 point scale, the selected respondents rated their operant definition on the perspectives on the coping strategies about practical stress in nursing student. The results of above procedures were analyzed by PCQ program. The perspectives on the coping strategies about practical stress in nursing student were analyzed based on the typical array, extreme comments, and the demographic information of study subjects. The results revealed that there were three types of the perspectives on the coping strategies about practical stress in nursing student. The three types were named as follows; 1) The first type, agree of positive change by oneself perspectives, was consisted of 18 subjects. They thought that they did their best positive change for the most effective coping strategies about practical stress. 2) The second type, agree of social support perspectives, was consisted of 13 subjects. They thought that they asked for an other person's help for the most effective coping strategies about practical stress. 3) The third type, agree of looking on avoidance perspectives, was consisted of 5 subjects. They thought that they looked on or avoided problems for the most effective coping strategies about practical stress. As a result, this study discovered three types of the degree of the perspectives on the coping strategies about practical stress in nursing student. By identifying the nature of each of three types, this study can be useful to develop efficient coping strategies about practical stress in nursing student.
