Is Autophagy a Prerequisite for Steroidogenesis in Leydig Cells?
김종민,박지은,김윤재 한국발생생물학회 2023 발생과 생식 Vol.27 No.3
We investigated the involvement of autophagy with steroidogenesis in testicular Leydig cells. Human chorionic gonadotropin (hCG)-stimulated T production in Leydig cells was not remarkably altered in the presence of an autophagy inhibitor 3-methyladenine (3-MA). Although pretreatment with 3-MA demonstrated a tendency to decrease hCG-induced T production, the differences were significant only at a higher time point of 24 h following hCG. Microtubule associated protein light chain 3 (LC3)-II was detectable in the control cells in all the experiments. The hCG-induced increase in steroidogenic acute regulatory protein (StAR) and cytochrome P450 side chain cleave (P450scc) protein levels were not significantly altered by 3-MA. Leydig cells isolated from immature rat testes 12 h following hCG treatment showed relatively increased levels of LC3-II protein compared to the control group. Furthermore, LC3-II levels shown in these cells reached almost the identical to those from normal adult testes. However, LC3-II protein levels were almost comparable or even slightly lower than the controls at 48 h following hCG. Expression of StAR and P450scc was upregulated at both 12 and 48 h after hCG. We also used MA-10 cells, the mouse Leydig cell line, in this experiment. When dibutyryl cyclic-AMP was treated with MA-10 cells, P4 levels were significantly increased in the cell culture medium. However, P4 levels tended to decrease in the presence of 3-MA, but the difference was not statistically significant. This was consistent with the results of the rat Leydig cell experiments. Together, we believe that although autophagy participates in steroidogenesis and enhances steroidogenic efficacy of Leydig cells, it may not be a decisive cellular process for steroidogenesis, specifically in the mature Leydig cells.
노사문제에 대한 가톨릭 교회의 공식적 입장의 역사적 변천(상) -〈노동현장〉에서〈80주년〉사이-

In deisem Artikel wird die offizielle Stellungnahme der romischen Katholischen Kircheuber Konflikte zwischen Arbeit und Kapital mit Schwerpunkt der historischen Entwicklung der Meinungen in den papstlichen Sozialenzykliken, insbesonders in Rerum novarum und Quadragesimo anno. Die Entwicklungsphase ist in Zwei Epochen getrennt und betrachtet, namlich die Erste Phase und die Zweite Phase. Die Erste Phase fasst den Zeitraum 1891-1961 um und die Zweite ist seit 1961 bis heute. Der Zeitraum der Analyse in diesem Artikel deckt nur die Erste Phase. Die Erste Phase kann durch konservative und apologische Verteidigung-stendenz charakterisiert werden, dennoch wahrend kieser Phase zeigte die Kirche eine Meinungsanderung : Am Anfang der Neuen Zeit scheint die Kirche eine grosse Schwierigkeit zu haben. Politische Demokratie und sprunghafte lndustrialisierung veranderte die sozio-okonomische Grundbasis fur die bis dahin geltende autoritat der Kirche. Papst Leo 13세 offenthichte seinen sozialen Rundbrief "rerun novarun", in dem er die offizielle stellungnahme imbeaug auf Sozialismus und auch gegen die sozialistischen Arbeiterbewegung. Kirche verstand die Arbieterbewegung als private Sache. Aber danach verstand die Kirche die Arbeiterfrage als ein soziale und offentliche Wesen, und die Kirche betont die vielseitigen SozialverpfLichtungen des Staates. Diese Meinungsentwicklung zeigt, dass die romische katholische Kriche eine grosse Rolle fur Weltweite Demokratisierung in Politik und Wirtschaft spielen werde.

It's difficult to find the analysis for the effects of detailed elements in common green roof. Consequently, in this study to analysis the effects of soil layers which is one of the detailed elements for green roof. We analyzed and compared the existence of soil layer, temperature dependent on the thickness and the amount of energy by one of the simulation program, Energy Plus 2.0. Savings energy for heating and cooling from the effect of the existence and thickness of soil layers was observed. We verified cold and heating effect of green roof to computer simulation certainly in this study. As a results of this study propriety and adaptedness of study by sequence of simulation in this study and wish to heighten propriety and authoritativeness of study through an experiment to future subject.

Information System Outsourcing is wide spread phenomenon in modern computerized business organizations. Through outsourcing, organizations can provide better service and acquire and maintain a competitive advantage. Recently, most of companies have an increasing interest about outsourcing for Information System. The outsourcing agreement is one of the technology transactions. The imperfection of the technology market causes critical two problems(the pre-contract and the post-contract hazard) for the trading parties involved. This study examines the post-contract hazard of outsourcing agreements from vendor`s perspective, specially, focusing on safeguards against the outsourcing company`s opportunism likely to reduce the value of the transaction-specific assets invested by the vendors. Designing an efficient governance structure to cope with the opportunism is one of the critical issues dealt with by Transaction Cost Approach. Transaction Cost Approach has suggested three options of safeguards for the trading parties to choose: the hierarchy, the hostage, and the contractual agreement with hierarchical elements. In this study an alternative to safeguard against opportunism is examined from the resource dependence perspective. In this study, transaction cost variables and dependence balancing variables are analysed as determinants of the vendor`s customer bonding behavior. Also, perceived level of vendor`s satisfaction is examine. 78 usable responses were returned form the survey, using this responses Factor, Correlation and Regression analysis are performed.
