There appears to be an increased incidence of anxiety symptoms in association with certain medical illness. It is usually assumed that certain medical disorders are directly associated with anxiety symptoms in that the pathophysilolgy of the medical illness somehow causes the anxiety symptoms. However, the pathophysilolgies of many such medical illnesses as well as anxiety are not known and no discrete group of medical illnesses is clearly more likely to produce anxiety symptoms than any other Moreover, anxiety symptoms may be the representation of other psychiatric symptoms, like depression and delirium. Though it is important to differentiate primary and other causes(secondary) of anxiety clinically, the clear differentiation is somewhat arbitrary, as the confusion of mind-body dichotomy. for the purpose of accurate treatment of anxiety symptoms relating medical illness, this review article focuses on those clinical features and mechanisms of anxiety that are potentially useful in differential diagnosis.

Objectives: This study aimed to evaluate the clinical efficacy of individual cognitive behavioral therapy (CBT) for Patients with Primary or Secondary Insomnia. Methods: Participants were recruited from a primary care sleep clinic from January 2008 to June 2009. The study sample included 64 outpatients with primary insomnia (n=30) and secondary insomnia (n=34) according to the criteria of DSM-IV. Participants completed sleep diaries, Dysfunctional Beliefs and Attitudes about Sleep Scale-16 (DBAS), State-Trait Anxiety Inventory (STAI) before CBT and shortly after completion of CBT. CBT was provided in 7 weekly, 40-50-minute individual therapy sessions. Results: Both groups of patients with primary and secondary insomnia showed significant improvement in the DBAS and sleep parameters including sleep onset latency, total sleep time, and sleep efficiency. Repeated-measures ANOVA of the DBAS and sleep parameters showed no significant group-by-time interactions between patients with primary and secondary insomnia, suggesting the efficacy of CBT for patients with secondary insomnia was equivalent to that of CBT for patients with primary insomnia. Conclusion: This study suggests that CBT is effective for the management of primary and secondary insomnia in a primary care setting.

The purpose of this study is to determine the association between physical activity and anxiety levels in Korean adolescents after COVID-19 Pandemic. This study performed a secondary analysis of the 16th Korea Youth Risk Behavior Survey 2020. Complex-sample descriptive statistics and the chi-square test were used for data analysis in SPSS 27. As a result, 60.9% of adolescents engaged in physical activity for more than 60 minutes a day and 39.1% of those did not. The level of anxiety among adolescents was found to be mild anxiety at 22.2%, moderate anxiety at 7.6%, and severe anxiety at 3.6%. A significant association was found between physical activity and anxiety levels (p <.001). Therefore, there should be a plan to increase physical activity in the national policy for the promotion of youth mental health.

파킨슨병은 손 떨림과 함께 행동이 느려지고 몸이 굳어지며, 보행이 느려지고 보폭이 짧아지며 자세가 불안해지는 것을 특징으로 하는 퇴행성 뇌질환이다. 파킨슨병의 가장 초기 증상은 비특이적으로 전신 위약감이나 피로감, 권태감 등이 있을 수 있는데 이럴 때는 병으로 인식하지 못하는 경우가 많고, 또 진단을 내리기도 어렵다. 좀 더 특징적인 증상들로는 휴식 상태에서의 손떨림이 가장 흔하며, 대화 시 발음 혹은 억양의 변화, 누웠을 때 혹은 보행 중 방향 바꾸기가 어렵다거나 걸을 때 팔의 흔들림이 줄어드는 증상들이 있을 수 있다. 이 외에도 걸음을 시작할 때 어려움을 느끼거나 의자에 앉거나 일어서기가 어렵고 글씨체가 작아진다든가 우울증, 침 흘리는 증상 등이 초기 증상으로 나타날 수 있다. 파킨슨병의 증상은 크게 일차적 증상과 이차적 증상으로 나눌 수 있는데 일차적 증상은 경직, 떨림, 몸의 움직임이 느리거나 줄어들고, 몸의 균형을 잡기 어렵거나 보행 장애 등의 증상들로서 흑색질의 신경세포 파괴로 생기는 직접적인 현상이다. 이차적 증상은 일차적 증상으로부터 파생되어 생기거나 흑색질 외의 다른 신경계의 침범에 의하여 생기는 증상들을 지칭한다.

투구운동은 견관절에 반복적인 압박력 및 신장력을 가하게 되며 이는 견관절의 정적 안정력의 약화를 유발하게 된다. 초기의 경도의 불안정성은 근육 등 동적 안정력의 작용으로 안정적인 운동상태를 유지할 수 있으나 반복적인 운동이 지속될 경우 근육이 피로해 져서 동적 안정력의 보상작용을 통한 안정성을 얻을 수 없게 된다. 이는 일차적으로 견관절의 불안정성을 유발할 뿐만 아니라, 이차적으로 견봉하 충돌증후 및 내적 충돌증후 등의 증상을 나타내기도 한다. 과 투구로 인한 대부분의 운동손상은 보존적 치료로 좋은 결과를 볼 수 있으며, 이는 일차적으로 투구를 중지하여 관절을 안정시키며 진통 소염제나 물리치료 등을 통한 항 염증치료, 그리고 회전근개 및 견갑골 주위근육의 강화운동 등의 단계로 진행된다. 적절한 보존적 치료에도 불구하고 증상이 지속될 경우 정확한 진단에 근거한 수술적 치료 및 조절된 재활운동 프로그램을 통해 조기 운동 복귀를 기대할 수 있다.

The purpose of this study was to examine the influencing factors of job engagement among Korean police officers. This was the secondary analysis of data from the 5th Korean Working Conditions Survey (KWCS). The study subjects included 185 Korean police officers. Collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation and multiple regression with IBM SPSS Statistics 24.0 program. Job insecurity (${\beta}=-.34$, p<.001), job reward (${\beta}=.39$, p<.001), subjective health status (${\beta}=.22$, p<.001), and organizational justice (${\beta}=.20$, p=.002) were significant influencing factors on job engagement, explaining 59.3% of the variance (F=34.26, p<.001). Effective and systematic strategies to improve Korean police officers' job engagement should focus on job reward, job insecurity, subjective health status, and organizational justice. The results of this study can be utilized as base data to improve Korean police officers' job engagement.

This study explores children's categories of emotion understanding from facial expressions onto two dimensional structure of emotion. Children of 89 from 3 to 5 years old were required to those facial expressions related the fourteen emotion terms. Facial expressions applied for experiment are used the photographs rated the degree of expression in each of the two dimensions (pleasure-displeasure dimension and arousal-sleep dimension) on a nine-point scale from 54 university students. The experimental results showed that children indicated the greater stability in arousal dimension than stability in pleasure-displeasure dimension. Emotions about sadness, sleepiness, anger and surprise onto two dimensions was understand very well, but emotions about fear, boredom were showed instability in pleasure-displeasure dimension. Specifically, 3 years old children indicated highly the perception in a degree of arousal-sleep than perception of pleasure-displeasure.

The two dimensional electron gas system based on GaAs/$Al_xGa_{1-x}As$ heterostructure is widely used for fabricating quantum structures such as quantum dot, quantum point contact, electron interferometer and so on. However the conductance of the device is usually unstable due to the presence of random telegraph noise in the device. To overcome such problem, we have studied the effect of surface state on the stability of the device by altering the surface state of the device with oxygen plasma. The dramatic improvement of the device stability has been observed after cleaning the device surface with oxygen plasma (by 50 W~120 W plasma power) for 30 sec followed by etching in HCl : $H_2O$ (1 : 3) solution.

The abnormalities in Hypothalamic-pituitary-adrenal(HPA) axis are associated with many psychiatric symptoms including depression. We present a report of a 71 year old man who was admitted to the psychiatric department presenting symptoms of headache, avolition, loss of energy, psychomotor retardation, poor appetite, insomnia, anxiety resulting from adrenal insufficiency and hypopituitarism. Hypothyroidism and electrolyte disturbance were managed and headache, insomnia, anxiety, GI symptoms were improved. But he remained in anergic state. After discharge, he was readmitted to infection department with high fever and drowsy mentality. Adrenal insufficiency was recognized and he was treated with corticosteroid replacement therapy. Finally his diagnosis was made as panhypopituitarism and overall symptoms were resolved. In this case, we showed how the atypical symptoms resulting from hypopituitarism develop and progress. Hypothyroidism, adrenal insufficiency, and growth hormone deficiency resulting secondarily from panhypopituitarism were associated with various nonspecific symptoms such as loss of energy, fatigue, insomnia, weight loss, decreased appetite etc. In clinical situation, differential diagnosis with depression is needed when clinicians were met a patient with these nonspecific symptoms. It is important that laboratory tests and differential diagnosis with endocrine diseases should be conducted, especially in geriatric patients with nonspecific symptoms like anergia, fatigue, poor appetite and so on.
