  • ICI 182, 780 (ICI) has been used as an estrogen receptor inhibitor in several mammalian species. This study was conducted to observe histological changes in the reproductive system of pubescent male mice following ICI treatment, as well as to investigate the recovery of the organs over time. To accomplish this, ICI at 5 mg/0.1 ml of castor oil was subcutaneously injected into 5-week-old male mice once per week for 4 weeks. The mice were then randomly divided into no-recovery, 150-day recovery, and 300-day recovery groups. The testis of the no-recovery group showed atrophy of the seminiferous tubules, with decreased Sertoli cell numbers and thickness of the germinal epithelium. In the epididymis, the cell height of epithelial tissues was altered, but these changes were not observed in the 300-day recovery group. In the efferent ductule, the luminal diameter was increased, but the cell height of the epithelial tissues was decreased. In the prostate and seminal vesicles, the cell height of the epithelial tissues was increased, and these changes were not observed in the 150-day recovery group. These results show that ICI causes histological changes in pubescent male reproductive organs but that these changes are resolved with time.

  • The dry etching of sacrificial $SiO_2$ was performed in supercritical carbon dioxide. The etching of boron phosphor silica glass (BPSG), tetraethyl orthosilicate (TEOS), thermal $SiO_2$, and Si-nitride (SiN) was investigated by using a two chamber system with HF/py etchant and alcohol additives. The etch rate of sacrificial $SiO_2$ increased upon the addition of methanol. The etch selectivity of BPSG with respect to SiN was highest with IPA although the highest etch rate was resulted from methanol except BPSG. The etch rate increased with the temperature in HF/py/MeOH system. Especially the increase of the etch rate was much higher for BPSG with an increase in the reaction temperature. The etch residue was not reduced apparently upon the addition of alcohol cosolvents to HF/py. While the etch rate in HF/$H_2O$ was higher than HF/py/alcohol system, the rate decreased with the addition of alcohols to HF/$H_2O$. The cantilever beam structure of high aspect ratios was released by the dry ething in supercritical carbon dioxide without damage.

  • A new Energy-Dissipating Sacrificial Device (EDSD) is developed for steel plate girders, which can effectively dissipate the energy stored in the structures during seismic actions. To verify the performance of the EDSD, various seismic responses of a sample bridge with the EDSD are analyzed in terms of energy, member forces and deformation. The full scale model tests are conducted to certify the performance of the EDSD when it is applied on existing bridges. Using the improved hysteretic model of the sacrificial member, the seismic analysis for an example bridge is performed. The results show that the proposed EDSD under seismic excitations can significantly decrease the energy stored in the bridge structures and reduce the relative displacements of each superstructure to the ground. The EDSD is also found to function as a structural fuse under strong ground motions, sacrificing itself to absorb the excessive energy. Consequently, economical enhancement of the seismic performance of bridges can be achieved by employing the newly developed energy-dissipating sacrificial device.

  • The paper investigates a mediating effect of job embeddedness in the influence of positive psychological capital on organizational citizenship behavior(OCB) for members of medical institutions. The members include medical doctors, nurses, medical technicians, health administrative staffs, and other medical service staffs of hospitals in Daejeon City, Chungcheongnam-do, Chungcheongbuk-do, and Sejong City. Using 453 questionnaires for hypothesis tests, the main results are as follows. Firstly, positive psychological capital exerts a significantly positive effect on OCB. Secondly, the fit and links of job embeddedness turn out to have a significant and positive effect on OCB, whereas the sacrifice does not have statistically significant effect on it. Thirdly, while the fit and links of job embeddedness appear to have mediating effects between positive psychological capital and OCB, the sacrifice of it does not exert a mediating effect. The findings thus suggest that we need a new approach to the role of job embeddedness in the positive impacts of positive psychological capital on OCB through the fit and links of job embeddedness. Furthermore, organizations need to focus on key elements in the application of job embeddedness.

  • The purpose of this study is to analyze the journal of reflection of students who participated in the character improvement education program. And it is a study that suggests ways to develop the program according to the results of analysis. Then, by collecting 208 reflective journals of students who participated in Milal training at K University, After the analysis was performed in the process of transcription, coding, and subject discovery, reliability was secured by calculating the Kappa coefficient for the analysis frame and analysis suitability. According to the results of the analysis of reflection journal. Through Milal training, the Milal spirit was understood as sacrificial service (sacrifice, devotion, lowering, serving, death, decay) and Milal (reproduction). We confirmed that It will have a life attitude related to the themes of labor (hardwork, work, patience, patience, perseverance). It can be said that through Milal training, self-reflection activities can be promoted, community character and collaboration skills can be cultivated, and the spirit of sacrificial service can be acquired. Through the results of this reflection journal analysis, it is necessary to further enhance the Milal training program, and it will be possible to provide implications to the character cultivation programs of other universities.

  • The purpose of this study is to analyze the compensation law for Special Mission Executors enacted to compensate for sacrifices for the state based on the policy framework proposed by Gilbert and Terrell and to present the limitations and development directions of the compensation policy. In particular, this study presents the characteristics of each dimension of the policy through the bases of social allocation, the types of social provisions, the strategies for the delivery, and the ways to finance. Through the analysis, We deduce problems of the compensation law for Special Mission Executors. Representative limitations of the compensation policy can be summarized as follows. Due to extreme selectivism, the limitations are the narrow selection criteria of the targets, the benefits which are not out of proportional to contributions, delayed benefits and the decrease in the size of public resources. These limitations suggest that the compensation policy for Special Mission Executors does not contain the significance of the Patriots and Veterans Affairs Policy. The value the Patriots and Veterans Affairs can be considered as a means for repaying the contributions who sacrificed for the nation. Therefore, the government needs to make efforts to develop a policy with the true significance of the Patriots and Veterans Affairs.

  • Do cultural differences affect moral decisions? Two studies were conducted to investigate whether attitudes of individualism vs. collectivism have an impact on ethical decision making. Study 1 (N=92) showed that utilitarianism was preferred in a situation, in which an intervention resulted in the best outcome (i.e., saving more people's lives), while deontology was preferred in a situation, in which the focus was on negative consequences of the intervention (i.e. personal sacrifices). Additionally, there were differences between the idiocentrics and the allocentrics groups regarding morality aspects. In the idiocentrics group, harm and fairness were regarded as more important than other moral aspects, while in the allocentrics group, not only harm and fairness, but also ingroup and authority were perceived as critical moral aspects. In Study 2 (N=30), after lexical decision tasks were conducted for culture priming, the mouse tracking method was used to explore response dynamics of moral decision processes, while judging appropriateness of interventions in moral dilemmas. In Study 2, in a condition, in which the small number of victims were focused upon, there were more maximal deviations and higher Xflips in the individualism priming group than in the collectivism priming group, which showed that the participants in the individualism condition had more deliberative processes before choosing their answers between utilitarianism and deontology. In addition, the participants in the individualism priming condition showed more maximal deviations in the mouse trajectories regarding ingroup related interventions in moral dilemmas than those in the collectivism priming condition. These results implicated the possibilities that the automatic emotional process and the controlled deliberative process in moral decision making might interact with cultural dispositions of the individuals and the focus of situations.

  • 프로젝트 관리는 통합적인 노력으로 수행되어 어떤 분야에 대한 특정의 조치 또는 불이행은 다른 분야에 영향을 미치게 된다. 즉 프로젝트 범위의 변경은 거의 대부분 프로젝트의 원가에 영향을 미치게 되지만 팀 사기나 품질에는 영향을 미칠 수도 있고, 그렇지 않을 수도 있다. 이와 같은 상호작용은 종종 프로젝트 목표들 간의 다음 그림과 같이 상호절충(Trade-Off)을 필요로 하여, 특정 분야의 성과가 다른 분야의 성과를 희생해야만 향상될 수 있는 경우도 생길 수 있기 때문이다. 한 프로젝트의 성공적인 관리는 이와 같은 상호작용의 적극적인 관리를 필요로 한다.

  • 방출형 토모그래피와는 다르게, 토과형 토모그래피를 위한 통계적 알고리즘들은 매우 늦은 수렴속도와 엄청난 계산시간을 감수해야 했다. 그 주된 이유는 Lange-Carson 모형에 기초한 EM 알고리즘을 사용하고 있기 때문인데, 최근 GCA 기법의 등장으로 계산 시간을 현저히 단축할 수 있는 가능성이 제공되었다. 그러나 GCA 알고리즘은 우도의 단조중가성을 만족시키기 위해 부가적인 계산시간을 희생해야만 한다. 이에 본 연구에서는 프로그래밍이 간편하며, 처리시간이 짧고, 자체로 우도의 단조증가성을 만족하는 투과형 토모그래피를 위한 재구성 알고리즘을 제안한다.
