본 연구는 육성기, 비육기 사료내 라이신 수준에 따른 재래흑돼지육과 개량종 돈육의 해동후 저온저장중 품질비교를 구명하고자 실시하였다. pH는 저장 5일에 고라이신 수준의 재래흑돼지육이 고라이신 수준의 개량종 돈육보다 높았으며(p<0.05), 드립감량은 저장 5일까지 고라이신 수준의 재래흑돼지육이 저라이신 수준의 개량종 돈육보다 낮았다(p<0.05). TBARS는 저장 7일에 고라이신 수준의 재래흑돼지육이 고라이신 수준의 개량종 돈육보다 높았다(p<0.05). Hunter L 값은 저장 2일부터 재래흑돼지육이 개량종 돈육보다 낮았고(p<0.05), a 및 b 값은 저장 5,7일까지 재래흑돼지육이 개량종 돈육보다 높았다(p<0.05). 신선육의 육색, 종합적 기호도는 고라이신 수준의 재래흑돼지육이 가장 높았으며(p<0.05), 가열육의 맛, 풍미, 조직감, 종합적 기호도는 재래흑돼지육이 개량종 돈육보다 높았다(p<0.05). 따라서 이상의 결과를 종합해 보면 고라이신 수준의 사료를 급여시 재래흑돼지육의 보수력, 육색, 관능적 기호도는 향상되었으나 저온저장중 지방산화는 촉진되었다.

급변하는 최근의 경영환경 하에서 다수의 기업이 자체개발보다 외주개발을 활용하는 추세이나 이에 따른 프로세스 관리의 어려움이 동반되고 있다. 본 연구는 외주개발과 자체개발의 정보시스템 개발 프로세스 관리수준을 비교하여 효과적인 프로젝트 관리방안을 살펴보는데 목적이 있다. 이를 위해 실제 프로젝트 관리에 광범위하게 사용되는 소프트웨어 프로세스 관리모형인 CMM(Capability Maturity Model)을 기반으로 정보시스템 개발 프로젝트 수행 경험자를 대상으로 설문조사를 수행하였다. 분석결과 외주개발 프로젝트의 평균적인 관리수준은 자체 개발 프로젝트에 비해 미흡하였다. 그러나, 외주개발 프로젝트의 관리수준 간에는 표준편차자 컸고, 상위 관리수준 프로젝트는 외주개발 프로젝트인 것으로 나타났다. 즉, 정보시스템 외주개발 여부를 결정할 때에는 단순히 외주개발에 관한 일반적 위험성을 고려하기 보다는 외주개발업체의 프로세스 품질관리 수준을 파악하는 것이 중요함을 알 수 있다.

As the income level of a country gets improved, people's social, economic, and cultural expectation will grow at the same time. Although the income level of Korea has been remarkably improved, her work-related fatality rate is the highest among OECD countries. Moreover, the rate hasn't been reduced for more than 10 years. This study aims to provide appropriate measures for work-related fatality reduction by comparing the income levels and the work-related fatality rates of countries and by analysing the problems of our worker-oriented accident prevention policy. For the comparison of income level and work-related fatalities, this study suggests income-level incorporated fatality rate, and it turned out that the rate of Korea is the highest among the countries. In order to find out the causes of that result, this study has found that our law enforcement is much weaker than that of UK, which implicates more strict law enforcement policy is needed to improve our work-related safety.

The present study examines whether fear of negative evaluation, social comparison and self-criticism mediate the relationship between insecure attachment and career indecision. Participants are 401 unemployed people in their 20s who have never had a job. The major findings of this study are as follows. First, correlation analysis indicates that both anxious attachment and avoidant attachment are positively related to fear of negative evaluation and self-criticism. Also, anxious attachment is positively correlated with social comparison, whereas avoidant attachment is negatively correlated with it. Second, both insecure attachments have significant positive correlation with career indecision. Third, it shows the respective unique mechanisms by which each of the two insecure attachment forms are related to career indecision are distinctive: Specifically, The linkage between anxious attachment and career indecision is partially mediated by self-criticism and social comparison, whereas avoidant attachment is indirectly related to career indecision through a full mediation of self-criticism and social comparison. Implications and limitations of this study are discussed.

The purpose of this study is to analyze the readability of the 2015 revised elementary science textbooks at the vocabulary and sentence levels, and to provide an opportunity to use vocabulary and sentences with an appropriate level of readability for writing textbooks in the future. To do this, the readability of the 2015 revised elementary science textbook was analyzed and the vocabulary and sentence level the readability of sentences defining scientific terminology were analyzed. The results were then compared to the readability of previous curriculum textbooks. The results are as follows: first, the grade average of vocabulary remained at 1.5-2.1, with vocabulary appropriate to the elementary school level being used on average. However, grades 4 to 5 vocabulary are distributed at a relatively high rate. Second, the sentence-level analysis shows that the sentence lengths for the third and fifth grades were relatively long and the percentage of simple sentences was low. Third, compared to other curriculum textbooks, it was confirmed that the proper level of readability was maintained at the vocabulary level, but that the sentence lengths and the percentage of simple sentences could adversely affect the readability of third-grade science textbooks.

The necessity of this study was to improve academic achievement and math attitudes through leveled reciprocal peer learning, and the specific purpose was as follows. First, each unit seeks to select learning methods and contents for each level of class for reciprocal peer learning, second, develop activity sites for each level through curriculum analysis, and third, improve academic achievement and math attitudes through classes that apply reciprocal peer learning activities. The study was conducted on 60 second graders of 00 High School in 00 Metropolitan City. Two classes were selected for the midterm exam results for the first semester of the second grade. Class 1 was divided into the experimental group and the other class 1 was divided into the comparative group, and 13 classes were conducted for about 2 months from May 1 to July 4, 2020. The experimental group (30 students) was a class that applied leveled reciprocal peer learning activities, and the comparative group (30 students) was a class that was taught based on traditional textbooks. As a result of this study, first, in this study, it was possible to improve academic achievement and math attitudes by setting learning contents for each unit and applying reciprocal peer learning activities for each level. Second, the experimental group taught by applying leveled reciprocal peer learning activities was effective in academic achievement and math attitudes compared to the comparative group taught based on traditional textbooks to students in the upper, middle, and lower groups. Third, in the class applying leveled reciprocal peer learning activities, low-level students who were neglected in math classes were also interested in the class and actively participated in it, showing improvement.

In this study, the relationship between the organizational characteristics of police officers and the level of post-traumatic stress disorder in the comparative analysis was to check for post-traumatic stress disorder, according to the organizational characteristics affect. To accomplish this, a way ANOVA analysis of variance(One-way ANOVA) was conducted. The department in post-traumatic stress disorder level, a significant difference was found. It was more likely to be exposed to a traumatic experience if who is working in the front-line department. Post-traumatic stress disorder according to the work unit, a significant difference was found. The level of Post-traumatic stress disorder in outside job unit officers was higher than that of desk job unit offcers. Post-traumatic stress disorder according to the rank and duration of employment and the administrative district level, a significant difference was not found.

The purpose of this study is to prevent obesity in the elderly and to seek differentiated intervention measures according to education level by comparing and analyzing the factors influencing obesity in single-person households according to education level. Using the data from the National Health and Nutrition Survey in 2020, cross-analysis and logistic regression analysis were conducted through data of a total of 400 respondents, and the analysis showed vulnerability in physical activities that could affect obesity if the education level was low, and risk factors such as eating out and sodium intake were high. As a result of comparative analysis of influencing factors through the classification of education levels, sedentary time was a risk factor in the low-education group, and sodium intake was a risk factor for obesity in the high-education group. Through this, it was discussed the need for healthy nutrition and physical activity education for middle-aged and elderly single-person households, and differentiated intervention according to the level of education.

1876년 Cutter의 개념을 계승한 AACR2R의 편목의 3수준은 오늘날과 같은 전자환경에서 유용하다. 본 연구에서는 편목의 다양한 수준에 관해 논의하였다. 최소수준목록(Minimal level Cataloging)은 영미에서 연구가 시작되어 미의회도서관과 OCLC에서 표준으로 제정하여 사용하고있으며, 핵심수준목록을 대표하는 PCC(Program for Cooperative Cataloging)의 핵심레코드(Core record) 표준은 최근들어 모든 수준의 도서관에서 사용이 증가되고 있다. 이에 인터넷자원의 표현을 위한 더블린코어와 PCC 핵심레코드의 데이터요소를 비교하여 공통데이터요소와 비공통데이터요소를 도출하여 인터넷환경에서 새로운 핵심수준 서지기술 데이터요소를 제안하는 기초자료로 삼고자 하였다.
