In this study this writer carried out survey and analysis on paving materials of children's playground for 40 apartment buildings with each of such apartment containing 100 households or more and which were built within last 15 years in Jeonju. As a result of analysis of such questionnaires this author could draw following conclusion. In the second half of 1990s pavement materials which were used mainly were sand and during first half of 2000s they were mixture of sand and rubber block and around 2010 they were rubber block or rubber chip pavements. Such change seemed to be a result of consideration of convenience for management and safety rather than in deference to diversity of children's outing places. Survey on the current status of pavement materials revealed need for directives by the main entity for management and their firm resolve for its implementation. And there was need for their coping with problems such as pressure of treading or lack of it or poor condition of drainage in case of sand and phenomena of pitting or dipping down, discoloring and poor drainage in case of rubber chips and rubber blocks and loosening of gaps between rubber blocks etc. Result of analysing status of usage disclosed that 50.4% of the respondents to questionnaires stated that they had experience of accidents. With regard to cause of such accident it was found that 47.5% of accidents were attributable to play facilities and 19.5% were due to paving (floor) materials thus it was disclosed that not only play facilities but also pavement materials had impact on safety for the children. Result of analysing level of satisfaction with pavement materials showed that pavement by rubber chips and blocks had higher level of satisfaction which was reflection of fear on cleanness of sand. In terms of preference rubber chip and rubber block pavements were highest and the next one was sand. Reason for such preference was based on concern with safety.

This paper describes an experimental Knowledge-Based Control System, named KBCS, for manufacturing and assembly. The KBCS of five parts and function : data-base, knowledge acquisition, optimization, and graphic monitoring. The KBCS is utilized for a FMS which is of five machine centers and automatic assembly lines. Each machine can perform almost all manufacturing functions which some difference in efficiency. Buffers store temporarily the incoming components and the outing components. Parts arrive at assembly lines after many steps of manufacturing, and the transfer path and time are determined by procedural knowledge of control systems. Nine different incoming components are set up. The total control system is expected to perform four algorithms, timing algorithm ,sequencing algorithm, penalty algorithm, and cart algorithm. The construction of controller require basic components of manufacturing systems in which knowledges are formulated on the base of the results and the repeated simulation of KBCS with graphic monitoring system. Simulation results by KBCS are compared with those by the other rules of manufacturing.

The purpose of the study was to investigate jean consumption among middle-aged Korean women and the characteristics of consumers as potential jean consumers. The data were collected from the survey of 238 Korean women aged 45 to 64 years old. The respondents prefer outlet store to other retail outlets and wear jeans mainly for travel, grocery shopping, and outing. The main reason for not wearing jeans is body change, which leads to poor fit in abdomen and waist area. The sample was clustered into two groups based on interest in jeans: high-interest and low-interest group. From the examination of group differences, the high-interest group rated conformity/brand reputation, scarcity, and attractiveness of appearance significantly higher compared to the low-interest group among the five clothing benefits pursued. No difference was found in obesity and body satisfaction. Group differences were found in recent purchase, price, number of jeans owned, and frequency of wearing jeans. The results suggest the characteristics of the potential jean market among middle-aged women in Korea. Implications are discussed.

We propose a novel simulation method for modeling the game of golf using SystemC, a system description language that allows modeling of a concurrent system's behavior. Utilizing the proposed simulator, we compare different outing formats of golf, namely, regular and shotgun, in terms of playing time. Our simulation results reveal that the shotgun format can take longer than the regular format if the number of groups in a golf course exceeds 33 for the scenario we tested, confirming the belief that the shotgun format can take longer than the regular format. We also justify our simulation by comparing the simulation and analytical results.

본 논문에서는 5.8 ㎓주파수 합성기에 대해 하모닉 발진을 적용하여 저가화 방안을 제안하였다. 제안한 주파수 합성기는 2.9 ㎓대역의 PLL 칩과 2.9 ㎓대역의 발진기, 그리고 5.8 ㎓대역의 버퍼 증폭기로 구성되어있다. 측정 결과는 5.65 ㎓에서 5.94 ㎓까지의 290 MHz주파수 가변범위와 약 0.5 ㏈m의 출력 전력, 그리고 100 KHz 오프셋 주파수에서 -107.67 ㏈c/Hz의 위상잡음을 보여준다. 기본 발진 전력(2.9 ㎓)을 포함한 모든 불요성분은 제안한 2차 하모닉 신호보다 적어도 15 ㏈c 이상 억압된다.

A $\kappa$-side switch box with W terminals on each side is said to be hyper universal, denoted by ($\kappa$, W)-HUSB, if it is routable for any global .outing with density at most W. In [5], we have proposed a switch box design strategy and designed a near optimum (4, W)-HUSB F(W) with 6.W switches. In this paper, we design, analyze and implement an efficient detailed routing algorithm for the S-box F(W). This router. can accommodate all routing requirement topologies.

본 논문에서는 지속되던 코로나-19 바이러스로 인한 일상의 제약이 점차 완화되는 추세 속에서 이전에 영위하지 못하던 개개인의 여가생활을 지원하기 위해 개발하였다. 제약이 완화되면서 많은 사람들이 국내 여행의사가 점차 증가된다고 분석된다. 지금 우리의 일상 속에는 인간이 직접 의사결정을 하는 부분들이 많이 줄어들었다. 공공데이터를 이용한 자동화된 경로 추천 시스템을 통해 사용자들은 의사결정의 단계 없이 제공되는 경로를 지도 API를 통해 시각적으로 이용하며 나들이 준비 과정을 간소화 시킬 것으로 예상된다.

This study was conducted in order to examine relationship between stroke patients' degree of satisfaction with leisure and quality of life according to their leisure activity types and whether they conducted leisure activities. A direct survey was performed from April 8 to May 3, 2013 on 92 inpatients and outpatients who received occupational therapy at hospitals located in Jeonju and Gunsan. A frequency analysis was carried out in order to look at the general characteristics of the subjects, their degree of participation in leisure activities, and their degree of satisfaction with leisure activities. A Pearson's coefficient was used to examine relationship between their degree of satisfaction and quality of life according to participation in leisure activities. Their degree of satisfaction according to participation in leisure activities was significantly higher when they took part in leisure activities such as handicraft activities, sports activities, or travel or tourism activities than when they did not perform any leisure activities. Their quality of life according to participation in leisure activities was higher when they conducted sports activities, outing activities, or tourism activities than when they did not. There was significant correlation between their degree of satisfaction with leisure and quality of life according to leisure activities.

A classical Lippmann equation valid for liquid electrodes can not describe the interfacial properties of solid electrodes due to the elastic surface strain on solid electrodes. Although there have been many attempts to derive the thermodynamic equations for solid electrodes Outing the past few decades, their validity has been still questioned by many researchers. In practice, although there are various experimental techniques to measure surface energy of solid electrodes, the results obtained by each technique are rather inconsistent due to the complexity of the surface strain on solid electrodes. This article covers these controversial issues in surface energy of solid electrodes. After giving brief summaries of the definition of the important thermodynamic parameters and the derivation of the thermodynamic equations for solid electrodes, the several experimental methods were introduced for the measurement of surface energy of solid electrodes. And then we discussed in detail the inconsistent results in the measurement of the potential of zero charge (pac) and the potential of electrocapillary maximum (ecm).
