Understanding of the reasons why users in recreation settings select particular trails may provide useful information for effective recreation resources management. This study investigated the present use of the major trails in Mudeung-san Provincial Park and the major influential factors on trail selection . This study was conducted in Mudeung-san Provincial Park stretching over Hwasun-gun and Damyang-gun of Chonnam Province and Kwang-ju city during August in 1996. Data were collected through on-site survey and mail-back questionnaire. 519(44.2%) out of 1173 survey samples were used for analysis. Reasons for selecting a particular trail were classified into 8 major factors. In overall, the order of the importance degree of the factors was 1) aesthetics of landscape, 2) safety(from physical and crime), 3) conditions for health, 4) quietness, 5) familiarity, 6) on the way to the destination, 7) convenience/social, 8) others` intention. There were differences in the degree of importance of each factor depending on trails, users` characteristics(eg., gender, age, group size, visit experience, etc.) and users` behavioral patterns. Recreation motivations were classified into 5 major factors. The order of the importance degree of the factors was 1) contacting with nature, 2) self-training, 3) solitude, 4) social interaction, 5) appreciating cultural properties. Regardless of trails, `contacting with nature` was the most important factor, and the degree of importance in the other 4 motivational factors showed only a little differences in order according to the trails. There were correlations between major factors for trail selection and recreation motivations. The results of this study may provide foundational information for establishing effective management strategies through better understanding of the present use of trails and influential factors on trail selection. It can be used for reducing the present social and ecological problems caused by use concentration on certain trails and providing users with better quality of diverse recreational experiences. This study discussed the findings, and suggested some management strategies based on these information.

In previous study, it showed that the MAP was greatly effective polishing process for magnesium plate. But it had lower efficiency than magnetic materials such as SM45C. It was very difficult to cut non-magnetic materials using the MAP process because the process was fundamentally possible by help of a magnetic force. This study aimed to verify analytically formation of the magnetic field in a case of the non-magnetic materials especially focused on magnesium plate. So, In this study, the magnetic density flux was predicted using simulation program. As a result, the magnetic density flux was lower at the center of pole on inductor than outside. It had same result on the experimental verification. And magnetic force was lower according to increase of working gap. So, to improve the magnetic force, permanent magnet was installed under the workpiece. In that case, the magnetic density flux not only at center but also at outside of pole was increased. Therefore, the efficiency of magnetic abrasive polishing was also increased. A design of experimental method was adopted for assessment of parameters' effect on the MAP results of magnesium plate for improving the magnetic force.

치유의 숲에서 다른 유형의 소리가 방문객의 기분상태(Profile of Mood States: POMS)에 미치는 영향

김상오,김상미,박승찬,최솔아 한국환경생태학회 2016 한국환경생태학회지 Vol.30 No.3

본 연구는 치유의 숲에서 다른 유형의 소리(무음, 자연, 음악, 아이들 노는 소리)가 방문객의 기분상태(Profile of Mood States: POMS)에 미치는 영향을 비교하였다. 자료는 2012년 10월 중 장성 ‘축령산편백치유의 숲’ 내에 위치한 ‘치유필드’를 이용하는 231명의 방문객으로부터 수집되었다. 각 피실험자는 각기 다른 유형의 소리에 노출되었으며 실험용 소리가 장착된 헤드셋을 착용한 상태에서 설문에 답변하였다. 실험결과, 기대했던 대로 ‘아이들 노는 소리’ 노출 그룹이 타 그룹에 비해 높은 부정적 기분상태를 나타냈다. 그러나 예측과 달리 자연소리와 음악소리는 피실험자의 POMS에 영향을 미치지 않았다. 이러한 경향은 총 기분장애 점수(Total Mood Disturbance Score: TMDS)뿐만 아니라 요인별(불안, 분노, 활력, 피로, 혼란, 우울) POMS에서도 동일하게 나타났다. 또한 혼잡지각(Perceived Crowding)수준 과 TMDS(r=0.568) 및 하위 요인별 기분상태(r=0.331-0.571)간에 정적 상관관계가 있었다. 연구의 결과에 대한 토의와 더불어 관리적 차원에서 연구결과에 대한 시사점을 제시하였다. This study compared the effect of different types of sounds(no sounds, sounds of nature, music, and sounds of children playing) on profile of mood states(POMS) in a healing forest. Data were collected from 231 respondents selected from among visitors to the 'Healing Field' in 'Jangseong Chukryongsan Pyeonbaek Healing Forest' in October, 2012. Each respondent was exposed to one type of sound . The results showed that there were differences in POMS among the different sound treatment groups. Sounds of children playing showed negative effects on POMS. Unexpectedly, however, sounds of nature and musical sounds had no effects on POMS. These tendencies were consistently found not only for total mood disturbance score (TMDS) but also for POMS by factors (i. e. tension, anger, vigor, fatigue, confusion, depression). Perceived crowding level was positively correlated with TMDS(r=0.568) and POMS by factors (range: r=0.331 - 0.571). This paper discusses the research results and suggests several managerial implications.

치유의 숲에서 조우수가 방문객의 혼잡 및 건강유익성 지각에 미치는 영향

Increasing concerns about human health and the awareness of the forest’s therapeutic benefits have led many people to visit the “healing forests.” The increase in users, however, may affect the therapeutic effectiveness of the forests. We explored the effects of encounter number on perceived crowding (PC) and user’s perceived healthfulness (PH) in a healing forest. Data were collected from 186 visitors to the Chonnam Pyonback Healing Forest and 315 college students using survey questionnaire in 2010 and 2011, respectively. The results showed that encounter number was strongly related with PC and PH. As encounter number decreased, PH increased and PC decreased. PC was also negatively related with PH. Generally, PH was not different between two studied locations. The findings suggest that too many visitors or tourists to the healing forest may reduce the therapeutic effects of the forest. Management implications are discussed. 인간의 건강에 대한 관심증대와 숲의 치유혜택에 대한 인식이 커지면서 많은 사람들이 “치유의 숲”을 찾고 있다. 그러나 이용자수의 증가는 그러한 숲의 치유 효과에 부정적 영향을 미칠 수 있다. 본 연구에서는 한 “치유의 숲”에서 조우수가 PC와 PH에 어떻게 영향을 미치는 지에 대한 탐색적 연구를 시행하였다. 자료는 2010년도 축령산 치유의 숲을 방문한 186명의 방문객과 315명의 대학생을 대상으로 한 설문조사를 통해 수집되었다. 분석결과, 조우수는 PC 및 PH와 관계가 있는 것으로 나타났다. 조우수가 감소함에 따라 PH는 증가하였으며 PC는 감소하였다. 또한 PC는 PH와 부정적 관계가 있는 것으로 조사되었다. 일반적으로, PH는 본 연구를 위해 선정된 두 장소 간에 차이가 없는 것으로 나타났다. 본 연구의 결과는 너무 많은 방문객 또는 관광객이 “치유의 숲”을 이용하는 것은 “치유의 숲” 치유효과를 감소시킬 수 있다는 것을 시사하고 있다.

Firmware Development Process for Food Refrigeration System

김상오,최영진 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.4

The refrigeration system is essential for preservingfood and processing frozen food. A system firmware is acommon and important feature in refrigeration system. However, it is difficult to verify the software, optimize theenergy efficiency, and solve the system fault withoutrefrigeration hardware. A virtual environment was establishedto verify software. The firmware developed in the virtualrefrigerator was ported into an actual refrigerator, and thenenergy optimization was performed by auto test system. Even after the firmware verification by the processes statedabove, and required tests were executed under strict testcondition, unexpected faults could be appeared when theyare used by consumers in the field. As a solution, newmethod using Internet was adopted to gather data, andsoftware defects were able to be reported in real time. Thisnew development process can be applied in all refrigerationsystems for food industry and other home appliances.

This study was conducted to suggest some alternatives to facilitate consumers’ purchase of EAP (Environment-friendly Agricultural Products) by comparing purchasers and nonpurchasers in terms of their socio-economic characteristics, EAP purchasing behaviors and perceptions, and overall evaluation on EAP. Data were collected by 562 Gwangju citizens selected through snowball and convenient sampling procedures in 2007. Purchasers were more likely to be female, older, and in a higher income level than nonpurchasers. Purchasers, who were more knowledgeable about EAP, had a higher tendency to obtain EAP information through more diverse sources, and more relied on EAP certification mark to distinguish EAP. Purchasers were also more concerned about the safety from pesticides and had more confidence in the safety of EAP than nonpurchasers. Purchasers were more likely to perceive the importance of 'facilitation of EAP’ and 'providing education and information about EAP’ than nonpurchasers. Generally purchasers tended to be more satisfied with EAP and higher intention to increase their EAP purchase in the future. Implications of the results were discussed.

Recent (2011–2017) foodborne outbreak cases in the Republic of Korea compared to the United States: a review

김상오,김상순 한국식품과학회 2021 Food Science and Biotechnology Vol.30 No.2

This study analyzes and compares foodbornedisease outbreaks reported in the Republic of Korea (KR)and the United States (US) during 2011-2017. The foodborneoutbreaks data in the KR and the US were collectedfrom the Ministry of Food and Drug Safety and from theSurveillance for Foodborne Disease Outbreaks UnitedStates, respectively. The average number of outbreaks andillness population were higher in the US than in the KR,but the KR’s illness ratio considering population size was2.4 times higher than that of the US. When the sites ofoutbreaks compared, the number of illness was the highestat schools in the KR whereas outbreaks at restaurants weremore frequent in the US. In the KR, bacterial infectionswere the primary cause of outbreaks while bacterial andviral infections accounted for the largest share of outbreaksin the US. Specifically, pathogenic E. coli presented asignificant risk in the KR whereas Salmonella was the mostprevalent in the US. These results indicate that the mainmicrobiological targets for detection and control in the KRshould differ from the US, which should be considered fordeveloping food safety related policies.
