성상경,신동환,송종호,이규항 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.6

연구목적: 남. 여 알코올의존 환자의 인구통계학적 특성, 음주력, 가족력, 음주양상, 음주동기, 공유질병 등을 포함하는 임상적 특성의 차이 및 여성 알코올의존에 대한 질병양상과 그 가족의 태도를 파악함으로써 향후 여성 알코올의존 환자의 치료 대책수립을 위한 기초자료를 제공하는데 그 목적이 있다. 방 법: 1991년 1월1일부터 1996년 5월31일까지 일 정신병원에 입원 치료한 남. 여 각각 51명의 알코올의존 환자를 연구대상으로 하였으며, 연구방법으로 병력기록지 및 설문지 조사를 통한 자료 수집을 이용하였다. 양군간의 비교를 위해 남. 여 인원 및 나이를 통제하였고, 여성 알코올의존자의 평균 연령은 44.45±11.02세였고 남성 환자군의 평균 연령은 44.17±10.08이었다. 진단은 DSM-Ⅲ-R에 의해 이루어졌으며 대상자 모두는 알코올 의존의 진단기준을 만족하였다. 결 과: 여성 알코올의존자는 남성 알코올의존자에 비해 음주시작 연령이 늦었고 과거 음주기간은 짧았으며 일 음주량이 적었다. 그리고 여성 알코올의존자는 남성 알코올의존자에 비해 자발적 입원이 많았으며 입원후 금단증상, 알코올성 간염, 당뇨등 신체적 합병증이 적었다. 또한, 입원후 가족의 태도에서 가족의 이혼위협 등 치료에 비협조적인 경우가 남성 알코올의존자에 비해 많았으며, 과거력상 사별, 이혼, 남편의 구타 등 상실의 경험이 많았다. 결 론: 남. 여 알코올의존자간에 인구통계학적 특성, 임상 특성, 가족의 태도 등 여러가지 면에서 차이가 나는 것으로 나타났다. 여성 알코올의존자 집단은 가족의 죽음, 부부생활의 갈등과 같은 심리 사회적 좌절 경험이 더 많고 가족들이 더 비협조적이었다. 그러므로 치료자는 이러한 여성알코올의존자의 특성을 치료와 예방에 반영하고 이들에 대한 세심한 배려를 해야할 것이다. Objectives: This study aimed to provide a basic data of female alcoholics by understanding the gender differences of the clinical characteristics including demographic characteristics, alcoholic history, family history, drinking patterns, reasons for drinking, and comorbidity in male and female alcoholics. It also ained to establish the therapeutic plans through understanding the patterns of disease and the patterns of family cooperation in female alcoholics. Methods: The study subjects consisted of 51 male and female alcoholics admitted to a mental hospital from January 1, 1991 to May 31, 1996. Subjects were age-and sex-matched. We reviewed patients charts and administered questionaires. Mean age of female alcoholics was 44.45±11.02 years and that of male alcoholics was 44.17±10.08 years. All male and female patients met with the DSM-Ⅲ-R criteria of alcohol dependence. Results: Female alcoholics were later in drinking-onset age, and to had shorter duration of previous drinking history and less average amount of daily drinking than male alcoholics. And female alcoholics were found to seek treatment more voluntarily, and to have less frequent delirium tremens after admission and less medical complications such as hepatitis and diabetes mellitus. Also female alcoholics had more frustration experiences of separation such as death of family member, divorce, and husband`s physical abuse. Female alcoholic`s families had more uncooperative attitude toward treatment such as threat to divorce after admission. Conclusions: There were many differences between male and female alcoholics of demographic characteristics, clinical characteristics, and patterns of family cooperation. Female alcoholics were found to have more experiences of psychosocial frustration including death of family member and marital conflicts, and more uncooperative attitude of her family members. Therefore, it is required that therapists consider the characteristics of female alcoholics upon treatment and prevention, and have more concern about female alcoholics.

치아 마모 환자에서 수직고경 증가를 동반하여 단일구조 지르코니아 보철물로 완전구강회복을 시행한 증례

과도한 치아 마모는 교합면에 손상을 야기하고, 치수 병변, 교합 부조화, 기능장애, 심미적 문제 등을 야기할 수 있다. 과도한 치아 마모를 갖고 있는 환자들을 치료하고자 할 때 수직교합고경(vertical dimension of occlusion, VDO)의 상실 여부와 수복을 위한 악간 공간의 적절성 여부에 기반하여 분류를 할 필요가 있다. 본 증례의 환자는 다수 치아들의 마모를 지닌 50세의 남성으로, 과도한 치아 마모가 있지만 수직교합고경의 상실은 없으며 수복을 위한 악간 공간이 부족하였다. 이러한 경우 수직교합고경을 증가시켜 치료를 진행하는 것을 고려할 수 있다. 수직교합고경의 증가를 필요한 범위 내에서 최소로 줄이고, 증가된 수직교합고경 상에서 안정화 기간을 거친 뒤 안정된 교합 접촉을 제공할 수 있다면, 수직고경 증가를 동반한 치료법은 안정성을 가질 수 있다. 본 남성 환자를 치료하기 위해 수직고경의 증가를 동반하여 전치부와 구치부에서 단일 구조 지르코니아를 이용한 고정성 보철물로 수복을 하였다. 일련의 치료과정을 통하여 기능적인 면과 심미적인 면에서 만족스러운 결과를 얻었기에 보고하는 바이다. Excessive occlusal wear results in unacceptable damage to the occluding surfaces, and can cause pulpal injury, occlusal disharmony, impaired function, and aesthetic deformity. Patients with severely worn dentition need to be classified as several categories relative to the vertical dimension of occlusion (VDO) and the interocclusal distance for the prosthetic space. When treating patients classified as those who have excessive wear without loss of occlusal vertical dimension but with limited space, we could consider treating them at an increased vertical dimension of occlusion. Treatments at an increased vertical dimension of occlusion may provide stability, given that the amount of its increase was minimal, and a perfected occlusion was achieved after enough stabilization period. A 50-year-old male visited the department of Prosthodontics in Yonsei University Dental Hospital with the chief complaint of worn teeth on lower anterior area. Reconstruction at an increased vertical dimension of occlusion was planned. After the compatibility of the new vertical dimension of occlusion had been confirmed under interim fixed restorations, definitive fixed restorations composed of full-contour monolithic zirconia prostheses were placed. This case presents that a satisfactory clinical result was achieved by restoring the worn dentition at an increased vertical dimension of occlusion with an improvement in esthetics and function.

본 연구는 폐석재와 석분을 사용하여 친환경적인 식생블럭 제품을 개발하기 위하여 폐석재의 입경과 석분의 첨가량을 각각 3종류씩 총 9종류의 식생블럭에 대하여 단위중량, 공극율, 투수량, 압축강도, 쪼갬인장강도, 휨강도, 내산성, 알카리농도에 대하여 구명하였다. 단위중량, 강도, 내산성은 골재의 입경이 작을수록 석분의 혼입량이 많을수록 크게 나타났으며, 공극율과 투수량은 작게 나타났다. 강도는 중성화 처리 유무에 따라 4∼5% 정도의 미소한 차이가 나타났다. 알카리 농도는 중성화 약품처리, 수중용출, 야외폭로 순으로 효과가 크게 나타났으며, 이는 식생블럭의 중성화 방법 선택에 매우 중요한 내용이라 할 수 있다. 또한, 식생상태는 공극율과 골재의 입경이 큰 식생블럭이 생육에 유리한 것으로 나타났다. This study was performed to develop the environment-friendly plantable block and to evaluate unit weight, void ratio, permeability, strength, acid-resistance and value of pH by the change of the grading of waste stone and the addition amount of stone dust. The unit weight, strength, acid-resistance is increased with small size of waste stone with increase of the addition amount of stone dust. But, the void ratio and permeability is decreased. The strength of neutral plantable block is decreased approximately 4-5% than that of the normal plantable block. The decreased effect of pH increased in order to neutral treatment, underwater leaching and field exposure. It is very important contents in neutral method selection of plantable block. Also, the planting state is grown rapidly with increase of the void ratio and of the waste stone size, approximately.

오성환,김경순,박종옥 慶星大學校 1995 論文集 Vol.16 No.2

Rapid and selective reduction of nitro compounds is of importance for the synthesis of amino compounds, particularly when a molecule has other reducible groups. In recent years, Bakers' Yeast has been used for enantioselective reductions of β-keto esters of α,β -unsaturated carbonyl compounds. However, little attention has been paid to the reduction of aromatic nitro compounds by Bakers' Yeast. In this paper, we wish to report a mild and selective reduction of m-bromonitrobenzene with Bakers' Yeast and glucose.

Appendicitis is one of the most common disease in emergency department(ED), but produces perplexing diagnostic problems. A complete understanding of the anatomy, pathophysiology, and presenting signs and symptoms of appendicitis, combined with thorough history and physical examination, will be the most important factors in allowing emergency physician to make the correct diagnosis of appendicitis. Situs inversus totalis is a rare congenital anomaly occurring in every 10,000 to 50,000 people. It's etiology is obscure but apparently dose not influence normal health or life expectancy. We present a case of perforated appendicitis with situs inversus totalis in a 24-year-old woman whose chief complaint was pain on the left lower quadrant of the abdomen. Chest and abdominal X-ray showed situs inversus totalis, but these typical findings of situs inversus totalis were missed before performing abdominal ultrasonography in ED. We must carefully consider whether congenital anomaly is or not by physical examination and X-ray finding. For patients whose diagnosis is less clear, additional diagnostic tool, for instance ultrasonography is recommended in ED.
