자기누설탐상시스템은 지하에 매설된 가스관에서 발생되는 부식이나 크랙 또는 기계적 변형을 탐지하기 위한 방법으로 비파괴검사 방법의 하나이다. 가스관은 Nd자석에 의해 착자가 되고, 가스관에 부식이 발생했을 경우 가스관의 단면적이 작아지게 되어 자기누설이 발생하며, 발생된 자기누설을 홀센서로 검출하여 부식의 유무, 크기, 모양 등을 판별하게 된다. 지하매설 배관은 배관의 직경은 같으나 배관의 두께는 다양하게 존재한다. 특히 30inch의 배관에는 배관의 두께가 11.1, 14.3, 17.5 mm 등이 있다. 자기누설탐상시스템은 배관의 단면적 변화를 감지하는 것이기 때문에 배관의 두께에 따라 그 특성이 변화하게 된다. 또한 두께에 따른 결함의 종류에 따라서 검출신호도 변화하게 된다. 따라서 본 논문에서는 배관의 두께 변화에 따른 검출신호를 분석하였으며, 두께 변화의 영향을 적용하여 검출신호를 보정하기 위한 방법을 제시하였다.

There could be different ways of perception, emotions, and behaviors facing on unfair situation according to the culture background by which people have been affected. We investigated whether definition, feelings, and behaviors in 4 countries (Korea, China, Japan, and the US) would differ in terms of unfair situations. We further examined the relationship between new self-construal model (subjectivity-objectivity-autonomy model) and behaviors resulted from unfair situations. Three hundred seventeen participants (87 Koreans, 71 Chinese, 80 Japanese, and 79 Americans) took part in this research. We found that all countries defined unfair situation as "having a disadvantage or blame that one did not done by him or her" with the highest percentage, but there was a different percentage according to countries. Next, Chinese felt disappointment or betray from the situations highly while others expressed anger with the largest portion. In the area of behaviors, three countries in Asia answered "no behaviors" with the highest percentage while Americans mostly responded "direct expressions". In terms of self-construal model, subjective self was high in Chinese and Koreans while autonomy was high in Chinese and American. Japanese showed objective self with the highest. Implications and future research are discussed.

The Records Centers' key institution is that ensure the continuity of custodys until records produced by the Office are transferred to the Archives. The transfer of records is the main works that the records center carries out annually. The introduction of the business management system in 2008 established electronic prodcuction and management of records. And Non-digital records have been registered and managed electronicallly on the system. This study analyzed the transfer procedure of non-digital records and the Transfer List between 2017 and 2019 by the Hamyang Office of Education Records Center. This study proposed improvement of transfer works by idnetifing and measuring the status of electronic management of non-digital records.

This study examined the relationships between learners' perception on parents academic involvement, academic self-efficacy, school adjustment, and career maturity, and also to analyze the hypothetical structural equation model relating three independent variables to career maturity. The participants were 443 sixth grade children(218 boys and 225 girls). The findings are as follows. career maturity positively showed the highest correlations with learners' perception on parent academic involvement, and academic self-efficacy. The findings revealed that learners' perception on parent academic involvement indirectly influenced career maturity mediated by academic self-efficacy and school adjustment. Furthermore, school adjustment displayed the highest direct effect on career maturity, whereas learners' perception on parent academic involvement showed the highest indirect effect on career maturity. It was discussed to develop and mange career program, career education, and career counseling effectively for elementary school children.

MFL PIG는 빠른 속도로 주행하면서 MFL 신호를 측정하여 기록하게 된다. PIG가 주행함에 따라 MFL 신호를 왜곡시키는데 가스관에 인가되는 강한 자기장으로 인하여 가스관이 착자되어 왜곡이 발생한다. 가스관의 착자는 종방향 착자와 횡방향 착자로 나눌수 있으며, 횡방향 착자는 검출신호를 증가시키거나 감소시키는 방향으로 왜곡을 발생시키고, 종방향 착자는 인가돼는 자기장과 수직이 되므로 검출신호를 크게 왜곡시킨다. 따라서 검출신호를 보정하여 실제 결함에 의한 신호를 검출하여야 한다. 본 연구에서는 가스관의 착자에 의한 영향을 분석하고 신호보정에 관하여 연구하였다.

The traditional Korean society has been classified as an Eastern collectivist culture, but in the flow of globalization and digitalization along with the post-Cold War era of the 1970s, Western individualistic culture and values quickly permeated the Korean younger generation. Since rapid changes occurred within a short period of time, there may be differences in cultural self-construal between generations living in the same era. Due to this, psychological problems related to emotional expression and suppression may appear differently depending on generations. Therefore, in the current study, 1,000 Korean adult men and women from their 20s to 60s were investigated for their level of independent and interdependent self-construal, alexithymia, ambivalence over emotional expression(AEE) and emotional suppression(ES). Then the relationship between the variables(self-construal and alexithymia,) and the mediating process of AEE and ES were examined. The generation of participants were divided into the industrialization cohort (birth year < 1970) and the digitalization cohort (birth year starting from 1970). Using the PROCESS macro(Hayes, 2022), we tested a serial mediation model of AEE and ES between the relative independent self-construal(RIS) and alexithymia. The results indicate that the level of alexithymia increases by the serial increase of AEE and ES when RIS decreases. Next, we examined a moderation effect of generatione on the mediation process of AEE and ES, and found that generation moderates the relationship between ES and alexithymia. That is, the effect of ES on alexithymia is significant for the digitalization cohort, while it is not significant for the industrialization cohort. The current results imply that emotion regulation strategies of Koreans have been differently developed according to prevailing cultural values in each generation, and that the negative influence of emotion suppression could be different according to the cultural background of each generation.

Due to the rapid increase in mobile-phone use, various kinds of malfunctions have occurred recently. Among them, the mobile-phone addiction causes serious social problems. In particular, since teenagers are immature, they are easily addicted to new technology. In order to prevent from the mobile-phone addiction, a lot of research has been performed in various ways. This paper focuses on the differences in gender and time perspectives of adolescent and analyze the relationships between time perspectives and self-efficacy for preventing mobile-phone addiction. In order to achieve our research goals, we firstly survey on 1,224 secondary school students to analyze the gender differences about time perspectives. And then, we secondly survey on 269 high school students to examine the mediation role of self-efficacy between time perspectives and mobile-phone addiction by a structural equation model. Based on the results of our analyses, we provide an educational guide that can prevent mobile-phone addiction from secondary school students.

With the enactment of the "Public Records Management Act" in 1999 and its revision in 2020, a records management system was established in the domestic public institutions. However, as the focus is on the management of public records, there are difficulties in managing the historical records of the university archives controlled by the nonelectronic records management system. To overcome these difficulties, this study looked at the case of Pusan National University Archives, which attempted to improve the function of the nonelectronic records management system using the "University Innovation Support Project." In particular, it is a case in which the function of the nonelectronic records management system was improved, catalogs reflecting the characteristics of resources were produced, and then the shelves were organized. It is hoped that the improvement of the nonelectronic records management system in Busan National University Archives will provide a positive direction for related organizations facing similar difficulties in the future.
