The paper presented not only the difference of the marginal walking time by passenger. but also the derivation of the bus service determination model by passenger attributes. The marginal walking distance to bus stop is a basic parameter to estimate bus service coverage area in certain area. And the marginal walking distance could be transformed from the marginal walking time, which is the focus of this paper. The result of analysis revealed that the age and income of passenger are strongly related to the marginal walking time. In planning or regulating the spacing of bus routes or bus stops in certain area, the model suggested in this paper help for the planner to choose optimal alternative.

The purpose of this study is to analyze the choice behavior of the mode of transportation for travel from Korea to China. Discrete choice analysis is utilized to establish the factors that affect travelers' choice and to quantify the importance of these factors in transportation mode choices. The proposed choice models were constructed by using stated-preference (SP) data obtained from Chungcheongnam-do. This study also examined different choice behavior in order to capture any previously unobserved differences in the residence area. Results showed that the access time and frequency attributes are the most significant factors, while the travel time attributes are the least significant factors for travelers' choice behaviour. The insights of the results described in this research provide some practical suggestions to transportation providers for planning and strategic management endeavors in the future.

Until 1960, the major housing type of rural area in Korea was traditional wooden frame building, which was made of natural materials. In the course of modernization and New Village Movement, most of traditional houses have been renovated focusing on changing roof material of rice straw into slate, keeping existing main wooden structure. And then from around 1980, by economical development the new houses have been constructed. On these three phases of traditional type, remodeling type and new construction type, the natural materials of housing facade as wood, soil, stone and plant changed into artificial materials as cement, chemical material and paint. At the same time the exterior color of housing also have been changed and varied. The purpose of this thesis is to find out the changing aspect of exterior color by comparing remodeled and new constructed housing with of traditional housing. The exterior color of one hundred and fifty seven houses were surveyed and the three color attributes of each part of facade, as roof, wall and window, were analyzed and compared. In case of traditional houses, 98.3% of color are concentrated on the warm color of Y and YR on HUE scale, and 88% of their color are low Chroma. And Value of their color has been varied and spreaded from low to high Value scale. From traditional types to remodeled and new constructed houses, the concentration ratio of warm color on Hue scale reduced from 98.3% to 68.7% and ratio of low Chroma was also changed from 88% to 73.2% and the ratio of low Value color reduced from 51.9% to 29.7%. The exterior color of houses in rural area varied on Hue, and the more saturated colors were used and they became brighter compared with color of traditional houses. It is expected that the results of this study can be used for basic data of exterior color planning and improvement into harmonized color with natural environment.

Recently, as technology development has accelerated and product life cycles have been shortened, it is necessary to derive key product features from customers in the R&D planning and evaluation stage. More companies want differentiated competitiveness by providing consumer-tailored products based on big data and artificial intelligence technology. To achieve this, the need to correctly grasp the required quality, which is a requirement of consumers, is increasing. However, the existing methods are centered on suppliers or domain experts, so there is a gap from the actual perspective of consumers. In other words, product attributes were defined by suppliers or field experts, but this may not consider consumers' actual perspective. Accordingly, the demand for deriving the product's main attributes through reviews containing consumers' perspectives has recently increased. Therefore, we propose a review data analysis-based required quality methodology containing customer requirements. Specifically, a pre-training language model with a good understanding of Korean reviews was established, consumer intent was correctly identified, and key contents were extracted from the review through a combination of KeyBERT and topic modeling to derive the required quality for each product. RevBERT, a Korean review domain-specific pre-training language model, was established through further pre-training. By comparing the existing pre-training language model KcBERT, we confirmed that RevBERT had a deeper understanding of customer reviews. In addition, all processes other than that of selecting the required quality were linked to the automation process, resulting in the automation of deriving the required quality based on data.

Objectives: This study aims to explore consumer awareness and usage patterns of local food in Jecheon city during the COVID-19 pandemic, contributing to the establishment of the Jecheon City Food Plan. Methods: Surveys were conducted from July 24 to August 24, 2021, using a combination of web-link and self-administered methods for adults living in Jecheon city (n = 250). Descriptive analysis, t-test, importance and satisfaction analysis (ISA) of local food choice attributes were performed using SPSS Statistics. Results: Participants prioritized freshness when purchasing agricultural products. The freshness of Jecheon local food was the selection attribute with the highest consumer satisfaction and could provide purchase motivation. Approximately 73.6% of respondents understood the concept of local food, and 70% were familiar with Jecheon's local food. Notably, 94.8% expressed an intention to purchase but held negative views on selling local food in other areas. The need to increase the supply of local food to vulnerable populations and public school catering was highly recognized. The ISA identified 'affordable price', 'delivery service', and 'product information' as areas requiring improvement. On the other hand, 'freshness of products', 'quality for the price', and 'support for local farmers and economy' were identified as attributes to be maintained and strengthened. Conclusions: Consumers in Jecheon city recognized local foods as more than just 'consumer goods'. Our findings suggest the need for further research on local food revitalization and more comprehensive local food planning to enhance consumer satisfaction.

With the proliferation of the "Untact" culture (non-face-to-face society), advanced technologies have accelerated the cashierless systems in the retail context. Cashierless fashion stores are expected to grow rapidly in the same way automated convenience stores grew in popularity. Applying the extended technology acceptance theory, this study aims to investigate how the attributes of cashierless fashion store influence consumers' acceptance of it and to examine how consumer's technology readiness moderates the model. Two online surveys-preliminary and secondary-were conducted to collect data from consumers in their 20s and 30s who had experienced cashierless stores over the past year. To analyze a total of 423 responses, this study conducted a confirmatory factor analysis, a multi-group factor analysis, a multi-group structure equation modeling, and a descriptive analysis. The results demonstrate that convenience, trustworthiness, and price had a positive impact on perceived ease of use, while service quality had a negative one. Enjoyment, convenience, trustworthiness, and price positively influenced perceived usefulness. Both perceived ease of use and usefulness increased the intention to use. Furthermore, the multi-group comparison confirmed that the positive dimensions of consumer's technology readiness played a moderating role in the model. This study provides a research foundation for consumer acceptance of technologically advanced stores and offers practical implications to companies planning cashierless fashion stores.

The Resilience is described as the personal capacity which brings psychosocial comeback. The role of nursing is to do its best to rehabilitate patients and to explore the individual in order to promote patients psychosocial change. However, as the current nursing is heavily physical nursing oriented, the identity of the nursing would be lost. Therefore this researcher reviewed if the concept of resilience can be applied to the nursing after examing the concept of resilience by Documents and Fieldwork. The methodology of this research is Hybrid Model developed by Schwartz-Barcott and Kim for the concept development and analysis. The process and procedure consist of The Theoretical Phase, The Fieldwork Phase and The Final Analytical Phase in accodance with the Hybrid Model. The followings the summary of the Research. 1. The Concept of Resilience Finally Analyzed by Documents and Fieldwork (1) The Redefinition of Resilience The resilience is the latent psychosocial capacity which minimize the negative emotion and promote the adaptation under adversity. Resilience appears as cognitive, emotional and behavioral response in the course of changing from negative response to positive response through the interaction of the individual and the enviroments in a given time. Resilience changes and decreases according to time and situation and it can be nurtured. Resilience is the higher concept including hardiness, sense of coherence and self-strength which maintain the health under stress. (2) The Attribute of Resilience The attribute of resilience was devided into psychological and social dimension. In psychological attributes, there are admittion of reality of situation, denial of negative emotion, desire to live, responsibility, confidence, courage, hope, pursuit of positive meaning, identification and pursuit of goal, self-esteem, reception, spontaneity, planning, positiveness, will power, flexibility and creativity. In social attributes, there are a sense of belonging, perception of social support and active social relations. (3) The Process of Resilience There are 4 resilience phases which were the process minimizing the possibility of the negative chain reactions under adversity, the process minimizing the negative emotion under adversity, the process gaining the desire to live and the process exposing the active social relations. 2. The Application Possibility of Resilience Concept to Nursing The resilience concept is the psychosocial capacity with which an individual manages adversity. As many nursing scientists have developed nursing theory based on this capacity and the identification of nursing has been established in this field, resilience is not the new conception in nursing. However, since resilience appears in the attributes related with the resilience process concretely, it would help a lot when nurses execute psychosocial nursing.

Considering the fact that quality of life(QOL) conceptually has objective and subjective attributes but difficulties in measuring the subjective aspect cause a number of studies not to be balanced, this study exploits AHP(Analytical Hierarchy Process) which has been used for systematic decision making to include the other aspect. As the first step of the process decision making hierarchy model is set by content analysis of the UNDP QOL index and additional review of previous studies. 'Improving urban QOL' is a goal on top, 'Economical QOL', 'Environmental QOL', 'Social QOL' and 'Physical QOL' are dimensions of sub-goal(means objectives), and further decomposition follows. AHP shows that the dimensions of economical, physical, environmental and social QOL scored higher respectively. The aim of the model is to measure and prioritize the urban QOL in the two case study cities. The final score of the each city could be computed by integration of relative weights of dimensions for urban QOL. The final score of QOL for city A was 0.6642 and for city B the figure decreased to 0.3358. The method of this study could be used in stages of the process of urban planning. First stage is when planners try to have a correct and reliable perspective from the existed conditions of the city. Second stage is when the projects should be investigated to be confirmed for their efficiency. In other words planners can direct the scarce resources towards the aspects of QOL which are more important. And the results revealed that using AHP creates opportunity to involving the different groups in the stage of criteria weighting so that the attitudes of local community could be integrated well to the decision making to be suitable for a new paradigm of participatory and communicative planning.

This study aims to seek a direction of development in apartment interior planning method, considering residential condition and historical planning schemes in South Korea and China. In this study, South Korea and China's traditional housing and modern apartment unit was studied to identify environmental attributes of residence. For Korea, Banga, where upper class residents lived, and modern urban Hanok were chosen to be analyzed. For China, two types of housing wear studied: Sahapwon, original form of China housing, and Yinong house which is a typical Sanghai house. First, the elements of living environment in two major cities; Seoul and Sanghai was defined to analyze factors of traditional houses in both cities. Depending on those factors, relationship among traditional and modern housing types were compared and analyzed, focusing on unit plan case studies for a better understanding of living environment in South Korea and China. From this study, similarities and differences between apartment plans in Seoul and Shanghai was examined according to their residential style, surrounding natural environment and lifestyle factors. In Seoul's apartment, spacial composition and movement lines were mainly formed around the public space in Seoul, while public space of living and dining room was located at housing entrance area in the Shanghai's residential system, configuring narrow form of housing unit. In respect of the natural environment, the unit plan of rectangular form in Seoul was more efficient in day lighting and wind circulation than the unit plan of narrow form in Shanghai. It was also found that cultural differences of stand-up and seat life style influenced on the composition of unit plans in Seoul and Shanghai.n Apartment cases in Seoul and Shanghai.
