알코올은 생물학적으로 피부부터 위장, 간장과 같은 장기와 말초 및 중추 신경계의 기능과 구조적 변화를 일으키며 그로 인하여 심리적, 생리적 의존과 함께 다양한 정신 장애를 일으킨다. 그리고 실직, 자살, 가정 내 폭력, 범죄 등의 사회적인 문제와 관련이 깊다. 이런 다양한 이유로 알코올 사용 장애는 타과로부터 흔하게 자문이 의뢰되어 조정되는 대표적인 정신신체 질환이다. 이에, 자문 조정 정신의학에서의 알코올 사용 장애의 유병률, 자문률 등의 현황을 살펴보고 알코올 상용장애 환자를 자문 조정하는 의사로서의 역할과 일반적인 원칙, 그리고 초기 치료 계획을 세울 때 고려해야 할 사항 등에 관하여 살펴보고자 한다.

The effect of the tool-sheet interaction on formability enhancement in electromagnetic forming is investigated using FEM. A free bulging and a conical forming die with 0.7mm AL1050 sheet are used to evaluate damage evolution based on Gurson-Tvergaard-Needleman plasticity material model. The impact between the tool and sheet results in complex stress states including compressive hydrostatic stresses, which leads to a suppression of void growth and restrain ascending void volume fraction of the sheet. Therefore, the damage suppression due to the tool-sheet interaction can be the main factor contributing to the increased formability in the electromagnetic forming process.

The objective of this study is to evaluate the detoxification method for the endocrine disrupting chemicals by manganese oxide. Manganese coated sand and bisphenol-A (BPA) was used as the reactive medium and the contaminant. Results showed that manganese oxide effectively degrades BPA by oxidative coupling reaction. The nonlinear oxidative coupling reaction orders were obtained for BPA and oxide, respectively. The reaction rate of BPA decreased as initial BPA concentration increased, as oxide loading decreased and as pH increased. The higher ionic strength, the higher reaction rate was observed. Divalent cations were adsorbed on the oxide surfaces, resulting in the decreased degradation rate of BPA.

Assembly is mentioned as important process saving time and cost where we produce the machine with many parts relationships. In this study, parts assembly relationship is analysed for assembly information of micro milling machine which have been developing for research. Liaison diagram, datum flow chain and assembly tree are applied to discuss assembly characteristics of micro milling machine model. We can find out the characteristics of micro machine assembly and discuss about facility of assembly. Some analysis in this paper about micro milling machine will give a useful tools for assembly. We knew that the predicted results from analysis in this study are alignment and clearance among the parts. The 3D model of micro machine which is studied in this paper is not a complete model. Main parts of a micro milling machine are used and presented.

Purpose: This study aimed to explore the experience of Fracture Liaison Service (FLS) coordinator nurses in a hospital setting. Methods: An in-depth interview was done using a semi-structured questionnaire on 4 FLS coordinator nurses between August 2022 and May 2023. A qualitative content analysis method was used for the data analysis. Results: Three themes of the experience of FLS coordinator were "The absence of identity of FLS coordinator," "struggling with the approach of creating something out of nothing," and "improvement of training and system to establish FLS coordinator role." Conclusion: This study identified three themes about the experience of FLS coordinator nurses in hospital setting. This finding is expected to be useful in developing education programs for FLS coordinator nurses.

The purpose of this study was to find the existential meanings of the culturally marginalized community organization. Based on the findings, the study examined the issues related to operating the organization and found the ways of helping such organization through service learning programs. For the study, the researcher chose the Korean school of Knoxville in the USA as a service community organization. This study used a qualitative method using narrative construction in the nature of the text shapes with first-person point of views. The research findings were discussed based on the observations and participation in the organization. The study found that the Korean school plays a role as a cultural liaison connecting the Korean culture to other cultures while enabling students to critically accept their native systems, values, and customs through understanding of their native language. However, problems were found in operating the school due to the lack of skills and knowledge of the school administration. Suggestions were made and implemented to the school in order to improve the performance of the school.

Novel $CO_2$-soluble 8-hydroxyquinoline (8-HQ) chelating agents were synthesized and evaluated for solubility and metal ion extraction ability in supercritical $CO_2\;(Sc-CO_2)$. Among them, secondary amide-containing 8- HQ derivatives cannot be dispersed well into Sc-$CO_2$, but tertiary amide-containing derivatives can dissolve completely in Sc-$CO_2$ even at low CO2 pressures, perhaps owing to the predominant intermolecular interaction between the chelating agent and the $CO_2$ molecule. Based on 8-HQ chelating agent solubility data, we investigated the extraction of metal ions ($Co^{2+}$, $Cu^{2+}$, $Sr^{2+}$, $Cd^{2+}$, and $Zn^{2+}$) using two highly $CO_2$-soluble 8-HQ derivatives (4d, 4e) in Sc-$CO_2$. The extraction efficiency of tertiary amide-containing 8-HQ ligands, both fluorinated and non-fluorinated forms, was dramatically increased in the presence of diethyl amine (organic base). We suggest that diethyl amine could play an important synergistic role in the stronger metal binding ability of 8-HQ through an in situ deprotonation reaction in Sc-$CO_2$ medium.
