겨울철에 동남아로 여행을 떠나다니 추위를 피할 수 있어 다행으로 생각하며 부러워하는 사람이 있었으나 사실은 그렇지 않았다. 속내의와 두툼한 외투를 입고 지내다가 평균 30$\circ$C가 넘고 습도가 높은 곳에서 지내기란 고역이었으나 세탁소 종업원들의 이상한 생각을 불러 일으켜가며 챙겨간 여름옷도 하루만 입고나가면 땀으로 흠뻑젖어 한 지역에 가면 첫날에만 입고 나가며 가장 즐겨 입은 웃옷은 간편하고 빨기좋은 나이론 남방이었으나 이런 온도차에 의한 고역은 지독하여 다시 한번 격게 되어 며칠간은 심한 몸살을 하게되었다. 1978년 새해들어 채 설 기분도 가시지 않은 1월 12일에 출국하여 제일먼저 들른곳은 홍콩대학교 의과대학 예방의학교실(Community medicine)이었다. 주임교수는 WHO의 Malaria Program과 싱가폴 대학에 있던 Dr. M.J. Colbourne으로 그날따라 토요일인 때라 그 다음 날에는 Hawaii에서 열리는 암의 역학적인 면에 관하여 회의가 있어 떠난다고 하며 무척 바쁜 눈치였다. 그곳에서 주로 하는일은 의과대학생들에 대하여 강의하며 1년에 몇명씩 대학원생도 받으나 올해는 한명도 없다고 한다. 물로 대학원생의 입학자격은 의사에 한한다. 두번째 들린 곳은 태국 방콕으로 시간을 많이 보낸곳은 Mahidol대학교 보건대학(Faculty of Public Health)이었다. 12개과에 139명의 교수진과 435명의 학생을 가진 큰 학교 이다.

현재, 사회가 정보화 되어감에 따라 교육분야에서 컴퓨터의 가치는 더욱 높아지고 있으며, 기존의 교실위주의 수업보다 시간적 공간적 제약을 덜 받게 되는 WBI(Web Based Instruction)는 무한한 발전 가능성을 가지고 있다. 하지만 기존의 WBI에서는 교수의 강의가 끝나면 수업 평가 후 학생에게 수업의 결과를 알려주는 형식이었고, 도한 학습자에게는 일률적으로 평가가 적용되어 학생의 수준에 맞는 수업을 할 수가 없었으며, 교수의 입장에서도 학생들의 평가 결과가 수업의 질을 높이거나 내용을 변경시킬 근거가 될 수는 없었다. 따라서 수준별 학습을 위한 단계별 예비 테스트와 학습 후 테스트의 평가내용을 다양한 방법으로 시각적으로 제시하고, 또한 교수가 평가의 준거를 입력하고 학습자의 평가결과와 교수자의 평가준거를 비교할 수 있는 교수지원 컴포넌트를 작성하고자 한다. 이는 체계적인 평가 방법론이 되고 학습의 패러다임을 바꾸거나 과목을 변경할 경우, 그 결과에 따라 교수 방법의 변화나 수업내용을 변경하고자할 때 용이하다. 또한 유사한 다른 패러다임의 WBI 시스템에서도 이미 개발된 컴포넌트를 사용함으로써, 사용의 용이성과 이식성, 재사용성을 높일 수 있게 한다.

Objectives : The aim of this study was to investigate the gender differences of direct aggression and relational aggression in Korean elementary and middle school students. Methods : Parents of 946 elementary school students(age $9.54{\pm}1.72$ years, 485 boys, 461 girls) completed the Child Behavior Checklist(CBCL). Six-hundred-and-three middle school students(age $13.98{\pm}0.93$ years, 301 boys, 302 girls) completed the Youth Self-Report(YSR). Independent t-test, chi-square test, and Fisher's exact test were used. Results : Boys had significantly higher direct aggression scores than girls in elementary school students(p<0.001). There was no significance gender difference of relational aggression in elementary school students(p=0.235). In middle school students, boys had significantly higher direct aggression than girls(p=0.017), and girls had significantly higher relational aggression compared to the boys(p<0.001). Conclusions : Our results suggest the presence of gender differences in manifestation of aggression subtypes in Korean elementary and middle school students. These gender differences should be taken into account in prevention and intervention approaches of aggression in children and adolescents.

Objectives: Suicide is the major public mental health concerns all over the world. The comparison of suicide attempters and suicide completers could be the fundamental evidence for the suicide prevention. The aim of this study is to explore the differences between suicide attempters and suicide completers in terms of the stressors, suicide methods, and psychiatric diagnosis. Methods: Two types of secondary data were collected for the analyses. Data of the suicide attempters (n = 680) were gathered by intensive reviewing the medical records of Samsung Medical Center, Seoul, Republic of Korea. Data of suicide completers (n = 11,722) were collected by the psychological autopsy data which were gathered by Korean Foundation for Suicide Prevention. Suicidal methods, psychiatric disorders and stressors before suicidal attempt were compared between suicide attempter and completers. Results: Suicide completers were older and male predominant compared to suicidal attempt. Hanging or gas intoxication were more commonly used in the suicide completion, while wrist cutting or drug intoxication were more common in suicide attempters. All types of stressors were found to be high in suicide completers than suicide attempters. However, the proportion of economic and physical stress were greater in suicide completers, while the proportion of family stress were greater in suicide attempters. According to the recorded diagnoses, the rates of depressive disorders, sleep-wake disorders, substance-related disorders were higher in suicide completers, while the rates of anxiety disorders and trauma- and stressor-related disorders, bipolar and related disorders and somatic symptom disorders were higher in suicide attempters. However, after controlling the gender and age, there were no significant differences in diagnosis between suicide attempters and suicide completers. Conclusion: These findings implicate that suicide attempters and completers differed in suicide methods and type of stress. The results suggests that economic stressors, physical illness might raise the risk of suicide completion.

Objectives : In this study, elderly hospitalized patients aged 65 years or older who were admitted to a university hospital and referred to the department of psychiatry were classified into youngest-old, middle-old, and oldest-old. It was conducted to find out what factors contribute to the agitation pattern by age group, whether there is a difference in the factors, and whether there is a difference in the severity of the agitation pattern. Methods : From July 1, 2021 to December 31, 2021, the medical records of patients aged 65 years or older who were referred to the department of psychiatry were retrospectively reviewed. Age, gender, route of hospitalization, department of referral, reason for referral, treatment method, presence of internal and surgical diseases, and hematological test data were investigated. Results : There was a significant correlation with the RASS score in cases of surgery referral and high CRP levels for youngest-old aged 65 to 74 years, in cases of surgery referral, dementia and hyponatremia for middle-old aged 75 to 84 years, in case of dementia for oldest-old aged 85 years old or older. In addition, there were differences in the severity of agitation patterns between age groups. Conclusions : As the age group increases, the agitation of delirium patients becomes more severe, and various factors contributing to the agitation pattern also differ by age group. Therefore, when treating elderly patients with delirium, attention should be paid to factors that may affect agitation depending on age.

In this study, clicker, also known as classroom response system, was applied to the chemistry method course at the university in Gyeongbuk, and preservice chemistry teachers' perceptions of clicker were surveyed. Before starting lecture, operation and class application of clickers were introduced to preservice teachers, and then 4-5 questions were presented to them in most classes during the term. After preservice teachers were asked to answer the questions, lecturer gave feedback based on the class answer distribution. Questions presented to preservice teachers were recall and/or understanding questions on learning contents, opinion questions, and questions about muddiest point. At the end of semester, preservice teachers were asked to rate their perception of clikers in terms of likert scale and essay type. They had positive perceptions of clicker use in aspects of cognitive effects, affective effects and media characteristics. They preferred conceptual understanding questions and monitoring questions among 8 clicker question types. Some cases using clickers in lecture and educational implications were also included.

In order to research the pathological entity of Jueyin disease in ${\ll}Shanghanlun{\gg}$, some sharing concept of three-yin-three-yang used in ${\ll}Neijing{\gg}$ and ${\ll}Shanghanlun{\gg}$ were investigated first, and then the meaning of jueyin and jueyin disease were analyzed. In cold damage disease, time-space factor is important because the pathological change is rapid and the symptoms along path are similar, therefore three-yin-three-yang having complex meaning of time and space can be used as an appropriate pathological concept. So to speak, it is able to be interpreted as various modes like variations of yin-yang, qi-blood, change of pulse condition, theories of opening, closing, pivot or exuberance and debilitation of form and qi manifested in the six districts of the human body following disease process. Jueyin is between front taiyin and rear shaoyin, and it's attribution is inherent in qi stagnation and yin exuberance in relative to the location of flank and liver. Putting together above descriptions, pathological entity of jueyin disease is that the symptoms mingled with cold and stagnant heat competing each other when a subject having qi stagnation in flank with cold in extremities and lower abdomen in particular is seized with cold influenza.

This study was conducted to confirm the mediating effect of the teacher's trust in the relationship between the classroom teacher's transformative leadership and the students' emotional stability from the organizational perspective. For this, the data from 290 middle school students in Seoul were collected and analyzed. As a result of the study, the transformative leadership of the homeroom teacher had a positive (+) effect on the trust of the leader. In addition, the teacher's trust in the leader had a positive (+) effect on the learner's emotional stability. In addition, it was confirmed that the teacher's transformational leadership had a positive (+) effect on the learner's emotional stability. Finally, in the relationship between the homeroom teacher's transformative leadership and the learner's emotional stability, teacher trust has a partial mediating effect. This study is meaningful in that it has objectively verified what kind of leadership the homeroom teacher should aim for in order to operate the classroom as the peripheral unit of the school organization, and what emotional and psychological effects such leadership can have on students who are members of the organization.

In this paper, the author found and analyzed the problems caused by the change of traditional teaching methods to online in classrooms and laboratories. Looking at the analysis of major problems, first, there were various technical problems, including not all environments and facilities being connected to the Internet. Second, the effectiveness of virtual classes, which were suddenly switched online, could also be questioned. Finally, in the face of a new environment, the stress of teachers to adapt rapidly to the new teaching methodology was a problem. The author proposed digital transformation as a way to address these problems. The author analyzed educational changes, learning modalities and various technical tools, and various tasks to enable digital transformation. First, the author investigated, analyzed, and presented the factors necessary to efficiently operate the classroom environment that will change to online. Next, the author analyzed the factors and problems needed to make the students' classes reliable and efficient, and proposed solutions. Finally, the author pointed out the problem that during online lectures, the responsibility of learning is excessively transferred from teachers to students, and proposed a solution to this problem. Subsequently, the author proposed future studies.
