This study aims to investigate how librarians' loyalty is affected by the organizational structure of libraries. For this purpose, 39 university libraries and 21 public libraries in Seoul were surveyed, and 126 questionnaires were collected and statistically analyzed. The main findings of the analysis are as follows. First, the centralization factor of organizational structure significantly affects the belongingness, responsibility, and devotion factors of loyalty. Second, the communication factor of organizational structure significantly affects the belongingness factor of loyalty, and it has a more substantial effect than centralization. Third, the moderating effect of library type on the effect of organizational structure on librarians' loyalty was found to be statistically insignificant. Based on the above results, this study suggests organizational structural measures to increase librarians' loyalty, and it is meaningful in that it is a study on an organizational field that has not been covered in depth in the literature.

The purpose of this study is to examine the impact of Ethical Leadership on job engagement, organizational commitment and unethical pro-organizational behavior and to analyze the dual mediation effect of job engagement and organizational commitment. We used 565 questionnaires collected by members in domestic companies. The result of the analyses are as follows: First, Ethical Leadership has no positive effect on unethical pro-organizational behavior. Second, in the relationship between Ethical Leadership and unethical pro-organizational behavior, job engagement does not play a mediating role, but organizational commitment plays a mediating role. Third, in the relationship between Ethical Leadership and unethical pro-organizational behavior, job engagement and organizational commitment play a dual mediating role. The theoretical implication is that this study once again confirmed the behavior patterns such as cognition, emotion, attitude and behavior of members in the organization. In addition, this study can contribute to theoretical expansion by explaining that these behavior patterns are identified by social exchange theory. The practical implication is that this study confirmed that members in the actual management field are willing to perform unethical pro-organizational behavior in order to achieve the organization's goal efficiently and effectively. Therefore, it is suggested that active efforts should be made to recognize these negative influences and possibilities at the organization level and to create a clean and fair organizational culture and environment that everyone can recognize at the social level.

랑게르한스 세포 조직구증은 골수에서 유래하는 랑게르한스 세포 조직구의 이상 증식에 의해 발병하는 희귀한 질병으로 알려져 있다. 비록 모든 장기에서 발생 할 수 있으나 갑상선을 침범하는 경우는 매우 드물다. 18세 남자가 5달전부터 점점 커지는 갑상선 종괴를 주소로 내원하여 세침흡인 세포검사, 총샘검, 경부 전산화단층촬영을 시행하였다. 세침흡인 세포검사에서 악성신생물이 의심되었고, 총생검에서 랑게르한스 세포 조직구증으로 나타났다. 경부 전산화단층촬영에서는 우측 갑상선에서 윤곽이 잘 구분되는 저음영의 종괴와 우측 기관 주위 림프절의 종대가 관찰되었다. 갑상선 전절제술과 우측 중앙 선택적 경부 림프절 청소술이 시행되었다. 랑게르한스 세포 조직구증이 갑상선을 침범하는 경우는 드물지만 갑상선 비대가 있는 환자가 뇌하수체 기능부전의 증상이나 뼈와 폐의 침범과 관련된 증상을 호소한다면 갑상선의 랑게르한스 세포 조직구증 침범을 고려해야 한다. 또한, 다른 장기의 랑게르한스 세포 조직구증을 치료한 과거력이 있는 경우는 갑상선 종괴를 감별 진단하는데 있어 랑게르한스 세포 조직구증을 고려해야 한다.

This paper showcases the study of 150 Coast Guard officers on how work environment compatibility impacts their organization and job attachment. The independent variable, work environment compatibility, is separated into three sub-variables, which are organization compatibility, job compatibility, and supervisor compatibility. The study's results show that job attachment is only influenced by job compatibility while organization attachment is influenced by all three; organization, supervisor, and job compatibility. With these results, we can make suggestions for the development of the Coast Guard organization and further research based on individual characteristics.

Photodynamic therapy (PDT) is one of the expectable current cure operation methods. Tumor tissue is treated by abundant oxygen in a body and generated singlet or free radical from exterior laser diode and photosensitizer. Current problem of PDT is the low penetration power of the light beam in a deep seated large tumor and solid tumor thus results in low treatment outcome. In the study, we tried to develop interstitial photodynamics therapy treatment to solve this problem. As the accurate determination of light dosimetry in biological tissue is one of the most important factors affecting the effectiveness of PDT, parameters used in this study are the optical property of biological tissue. Since biological tissues have large scattering coefficient to visible light the penetration depth of a biological tissue in visible light region is only $15\~20$ mm. We showed that it is possible to measure fluence rate and penetration depth within the biological tissues by Monte Carlo simulation very well. Based on the MC simulation study, the effectiveness of interstitial photodynamic therapy on tumor control in solid tumor was proved through in vivo animal experiment.

3D histology is a imaging system for the 3D structural information of cells or tissues. The synchrotron radiation propagation phase contrast micro-CT has been used in 3D imaging methods. However, the simple phase contrast micro-CT did not give sufficient micro-structural information when the specimen contains soft elements, as is the case with many biomedical tissue samples. The purpose of this study is to develop a new technique to enhance the phase contrast effect for soft tissue imaging. Experiments were performed at the imaging beam lines of Pohang Accelerator Laboratory (PAL). The biomedical tissue samples under frozen state was mounted on a computer-controlled precision stage and rotated in $0.18^{\circ}$ increments through $180^{\circ}$. An X-ray shadow of a specimen was converted into a visual image on the surface of a CdWO4 scintillator that was magnified using a microscopic objective lens(X5 or X20) before being captured with a digital CCD camera. 3-dimensional volume images of the specimen were obtained by applying a filtered back-projection algorithm to the projection images using a software package OCTOPUS. Surface reconstruction and volume segmentation and rendering were performed were performed using Amira software. In this study, We found that synchrotron phase contrast imaging of frozen tissue samples has higher contrast power for soft tissue than that of non-frozen samples. In conclusion, synchrotron radiation propagation phase contrast cryo-microCT imaging offers a promising tool for non-destructive high resolution 3D histology.

The concept of 'Implant Supracrestal Complex (ISC)' was introduced as a way to determine the impact of implant prosthetic design form on both short-term clinical outcomes and the long-term prognosis of bone and soft tissues around the implant. Implant-prosthesis-abutment complex design forms, such as implant-abutment design, junction, and location, can have important implications for the stable and healthy long-term maintenance of the tissues around the implant. In this case, a customized concave abutment and a prosthesis with an emergence angle of about 30 degrees were restored to a patient suffering from chronic soft tissue inflammation and pain after restoration of an implant prosthesis. It was confirmed that the new prosthesis improved complications by allowing sufficient bone and soft tissue space, achieved appropriate soft tissue sealing, and maintained the long-term stability of the implant.
