This study is to promote barrier-free environment to accommodate the request and the need for accessibility and convenience of disabled people including pregnant women, children and the elderly in using civic service offices which are supposed to play a role as community centers. This study researches the current state of facilities for convenience and analyzes the result according to the type of reasons which prevent disabled persons to get the accessibility and convenience for the information as well as the facilities. Sample cases are 15 civic service offices which are newly built after 1998 in the city of Daegu. There are found three types of problems about convenient facilities, which are the first cases with facilities not installed, the second cases with facilities not properly installed according to the rule, and the third cases with facilities installed properly according to the rule but inconvenient for the actual use. This study proposes a more critical process for the building permit to promote the rate of proper installation of convenience facilities, and the supplementary law with more specific regulations to improve the physical environment for the actual use of physically disabled people.

Objectives: This study aimed to assess the adherence to dietary guidelines among college students in the post-COVID-19 era and examine the changes in their dietary habits as the learning environment transitioned from remote to in-person classes. Methods: We conducted a survey involving 327 college students in Daejeon from March to April 2023. The survey questionnaires included various factors, including age, gender, type of residence, frequency of use of delivery food, convenience food, and eating out. In addition, we investigated the extent of adherence to the dietary guidelines for Koreans and the degree of dietary changes following the post-COVID-19 shift in class format were investigated. For comparative analysis of the level of adherence to dietary guidelines in relation to dietary habit changes, an ANOVA and a post hoc Scheffe test were employed. We also performed a multiple linear regression analysis to identify dietary factors influencing the level of adherence to dietary guidelines. Results: The study revealed a high rate of convenience food consumption and a low rate of homemade food intake among students. There was a marked increase in the consumption of processed foods, convenience foods, dining out, sweet foods, high-fat fried foods, beverages, and alcohol following the transition from online to in-person classes. When examining adherence to Korean dietary guidelines, the highest scored practice was 'Hydration', and the lowest was 'Breakfast habit'. Increased consumption of convenience foods, late-night snacks, and dining out were negatively correlated with adherence levels to dietary guidelines, specifically correlating with 'Healthy weight', 'Hydration', 'Breakfast habit', and the total score of adherence. The adoption of 'regular meals' was positively associated with increased adherence levels to dietary guidelines. Conclusions: The transition from remote to in-person classes post-COVID-19 led to increased intake of convenience foods, dining out, sweet foods, high-fat fried foods, and alcohol. The rise in convenience food and late-night snack consumption negatively influenced several aspects of the dietary guidelines adherence, thereby suggesting the need for strategies to encourage healthy dietary habits among college students.

본 논문은 전동 보행보조기의 편의성 향상을 위한 최적의 제어 이득을 찾고 제어 알고리즘을 설계하였다. 최근 노인의 인구가 의료 기술의 발달로 급속히 증가되고 있으며, 다양한 이동형 보행보조기구는 삶의 질을 개선하기 위해 개발되고 있다. 이러한 이동형 제품 중 수동형 보행보조기는 노인의 보행의 힘을 도와주는 전동모터를 가지고 있지 않아 노인들이 충분한 근력이 없기 때문에 경사로 및 문의 문턱 등 고르지 않는 지형에서 이동하는데 제안사항이 있다. 이러한 상황을 극복하기 위해 전동타입의 보행보조기를 개발하였다. 전동형 보행보조기는 수동형과 다르게 사용자가 조작을 해야 모터가 구동되는 구조이다. 이러한 구조는 사용자가 조작을 잘못 하였을 경우 상당한 불편함을 사용자에게 준다. 이러한 전동형 보행보조기를 수동형 보행보조기와 비교하여 조작의 편의성을 판단하고 기준을 만들어 사용자의 편의성에 대하여 제어 값을 변경하면서 사용자 편의성을 개선하였다. 본 논문에서는 보행의지를 인식하고 편의성의 성능을 측정할 수 있는 방법인 햅틱 센서를 소개하며 편의를 개선하는 제어 알고리즘을 제안한다. 또한 편의성의 평가는 COV(Center of Vehicle)와 사용자의 COP(Center of Position)과의 차이의 변화를 통해 상대적인 편의성을 평가하였다. 전동 타입 보행보조기와 새로운 측정방법을 도입하여 모든 과정을 실험을 통하여 확인 하였다.

The conduction velocity of the nerve is of importance to the diagnosis of various negromuscular disorders. A major technical problem encountered in nerve stimulation technique is the control of stimulus artifact and the convenience of nerve stimulator. The remained artifacts must be removed by processing the contaminated signal. This paper discusses about the artifact cancellation algorithms in constant voltage type nerve stimulator(CVS) and constant current type nerve stimulator(CCS).

The aim of this study was to classify Korean consumers based on their food-related lifestyle type, and to investigate the relationship between sushi consumption and food-related lifestyle type. Self-reported questionnaires were completed by 300 Korean adults. The SPSS 18.0 program was used to analyze the samples. Data was analyzed by frequency, descriptive factor, reliability, cluster analysis, ANOVA, and chi-square test. A factor analysis extracted four factors comprising foodrelated lifestyle, which we named Health-seeking (factor 1), Taste-seeking (factor 2), Convenience-seeking (factor 3), and Economy-seeking (factor 4). According to a cluster analysis based on those four factors, consumers were classified into three clusters. Cluster 1 was the Taste and Health-seeking cluster, Cluster 2 was the Convenience-seeking cluster, and Cluster 3 was the Passive Eating Habits cluster. The results also indicated that the selection attributes of each cluster were significantly different in terms of perception, the global state of sushi, sushi preference, frequency, companions, place of sushi consumption, and preference for different sushi sub-ingredients. Based on these results, consumer characteristics in the sushi market are discussed.

The purpose of this study was to evaluate and to analyze the spatial composition by block plan of the free elderly facility and to provide basic information for building up the detail architectural guidelines. The results of the study were as follows: Elderly welfare law needed to control the poor physical environments of the free elderly facility such as the residential space for more than 4 individuals. The facility of single building type should strengthen the informal support networks through the dispersion of public spaces or should encourage moving of the residents through the outdoor space, especially in rural area. On the other hand, the linking type needed to focus on the administrative spaces on the first floor for the managerial convenience, and to group and disperse the public/recreational spaces to decrease the unnecessary moving of the residents and staffs. The passageway linking building to building should directly connect each administrative space or public space so that elderly used them without any inconvenience. In the dispersion type, which is suited to rural area, the lounge, dining hall, and the place for the staff on duty should be located in the same as the residence building for the convenience and the safety of the elderly residents.
