Han, Doug Hyun,Lee, Jung Jae,Moon, Duk-Soo,Cha, Myoung-Jin,Kim, Min A,Min, Seonyeong,Yang, Ji Hoon,Lee, Eun Jeong,Yoo, Seo Koo,Chung, Un-Sun The Korean Academy of Medical Sciences 2016 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.31 No.1

<P>We aimed to validate the Inventory of Complicated Grief (ICG)-Korean version among 1,138 Korean adolescents, representing a response rate of 57% of 1,997 students. Participants completed a set of questionnaires including demographic variables (age, sex, years of education, experience of grief), the ICG, the Children's Depression Inventory (CDI) and the Lifetime Incidence of Traumatic Events-Child (LITE-C). Exploratory factor analysis was performed to determine whether the ICG items indicated complicated grief in Korean adolescents. The internal consistency of the ICG-Korean version was Cronbach's α=0.87. The test-retest reliability for a randomly selected sample of 314 participants in 2 weeks was <I>r</I>=0.75 (<I>P</I><0.001). Concurrent validity was assessed using a correlation between the ICG total scores and the CDI total scores (<I>r</I>=0.75, <I>P</I><0.001). The criterion-related validity based on the comparison of ICG total scores between adolescents without complicated grief (1.2±3.7) and adolescent with complicated grief (3.2±6.6) groups was relatively high (t=5.71, <I>P</I><0.001). The data acquired from the 1,138 students was acceptable for a factor analysis (Kaiser-Meyer-Olkin Measure of Sampling Adequacy=0.911; Bartlett's Test of Sphericity, χ<SUP>2</SUP>=13,144.7, <I>P</I><0.001). After omission of 3 items, the value of Cronbach's α increased from 0.87 for the 19-item ICG-Korean version to 0.93 for the 16-item ICG-Korean version. These results suggest that the ICG is a useful tool in assessing for complicated grief in Korean adolescents. However, the 16-item version of the ICG appeared to be more valid compared to the 19-item version of the ICG. We suggest that the 16-item version of the ICG be used to screen for complicated grief in Korean adolescents.</P>

The existence of a genetic predisposition to tardive dyskinesia (TD) in human has been suggested. The purpose of this study was to assess whether haloperidol induced extrapyramidal symptom (EPS) and TD are associated with the polymorphisms of the genes encoding for the catechol-o-methyltransferase and serotonin transporter in Korean schizophrenic patients. Male schizophrenic patients who underwent haloperidol treatment for more than 3 consecutive months were recruited as the subjects in two psychiatric hospitals. All of the patients were evaluated by the extrapyramidal symptom rating scale and abnormal involuntary movement scale. The incidence rate of TD patients with the COMTH/COMTH genotype was higher than those with the COMTH/COMTL and COMTL/COMTL types. There were statistically significant differences with respect to the effect of the 5-HTTLPR genotype on the incidence rate of patients with EPS. The COMTL allele played a more significant role in the incidence of TD than the 5-HTTPR L allele. According to our results, COMT was associated with the incidence of TD while 5-HTTLPR was associated with the incidence of EPS in the schizophrenic patients treated with haloperidol.

Introduction: Although alcohol driving has caused enormous economic and social loss and threatened the safety of human life, the educational system has just been regarded as offering information. We would report temperamental characteristics of person with drink-driving(drinking drivers) for suggesting proper educational data. Method: Forty four drinking drivers who participated in drinking driver educational program has been recruited. The educational program was held every month by Korean Probation & Parole office. For the alcohol dependence group, fifty one patients have been recruited who were admitted with the diagnosis of alcohol dependence by DSM-Ⅳ diagnosis criteria. Control group was forty eight persons who worked in hospital. For the measurement tool, Alcohol Use Disorders Identification Test: AUDIT-K, Alcohol Dependence Scale: ADS, Temperament and Character Inventory were used. Result: Harm Avoidance(HA) score had significant difference in three group. And the subscales of harm avoidance(HA1, HA2, HA3, HA4) had also significant difference between three group. In alcohol dependence group, the score was most high. And control group had higher score than drinking driver group. Novel Seeking(NS) score and the subscales(NS1, NS2) had no difference between control group and drinking driver group. There was significant difference in alcohol dependence group compared to these two groups. The subscale NS4 had significant difference in three group and alcohol dependence group had most high score. The subscale NS4 score was higher in drinking driver group than control group. Conclusion: It seems that motivation and education to raise self-efficacy would be more effective for drinking driver, because, generally speaking, they can easily be friendly to other people and strange situations, tend to never get tired easily, and have ability to maintain their own energy without coercion.

연구목적: 원예작업은 정신 질환이 있는 환자에게 사회적 기능 및 인지 기능을 향상시키고 자존감을 높이는 효과가 있다. 만성 정신분열병 환자의 치료에 있어서 인지 기능의 향상은 사회 재활 훈련에 긍정적 효과를 나타낸다고 알려져 있다. 이에 저자는 만성 정신 분열병 환자군에서 원예 작업 치료를 시행하여 작업에 따른 인지 기능 및 증상의 변화를 관찰하였다. 방 법: 정신분열병으로 진단 받은 후 5년 이상 지속적 외래 및 입원 치료를 받은 과거력이 있는 남자 환자 중 원예작업을 실시한 자발적 지원자 33명을 환자군으로 하였고 원예작업을 실시하지 않은 28명을 대조군으로 하였다. 원예작업 시작 전과 5개월 후에 인지 기능을 숫자 외우기(Digit span), 계산(Calculation), 바꿔쓰기(Digit Symbol Substitution Task from the Wechsler Adult Intelligence Scale-III), Trail Making Teat-A(TMTA)로 측정하고 증상은 Scale for the Assessment of Positive Symptoms (SAPS), Scale for the Assessment of Negative Symptoms(SANS), Brief Psychiatric Rating Scale(BPRS)로 측정하였다. 결 과: 환자군은 대조군에 비해 바꿔쓰기, TMTA 항목에서 통계적으로 유의한 향상을 보였다. 환자군 음성 정신분열병군이 대조군 음성 정신분열병군에 비해 바꿔쓰기, TMTA 항목에서 통계적으로 유의한 향상을 보였다. 양성 증상, 음성 증상, 인지 기능 상호 간에 영향은 없었다. 결 론: 원예작업은 만성 정신분열병 환자의 인지 기능의 향상을 도모하며 이에 따른 빠른 일상 생활의 수행 능력과 대인 관계의 향상, 직업 생활로의 연계에 있어서 큰 도움을 줄 수 있다. Object:Gardening improves the cognitive function & social interaction of psychiatric patients. The improvement of cognitive function in chronic schizophrenic patients is related to the good result of social skill acquisition training. In the study, we compared the cognitive function & symptoms of chronic schizophrenia patients before gardening with after that. Method:Thirty three chronic schizophrenic patients were assigned to gardening. Neuropsychological test & symptom scale for pretest-posttest(5months later) comparison consisted of Digit span, calculation, Digit Symbol Substitution Task from Wechsler Adult Intelligence Scale III(DSST), Traio-Making Test-A(TMTA), Scale for the Assessment of Positive symptoms(SAPS), Scale for the Assessment of Negative symptoms(SANS), Brief Psychiatric Rating Scale(BPRS) . Result:The gardening group showed significantly improvement in DSST & TMTA. There was no relationship between symptoms & cognitive function test. The gardening group especially in negative schizophrenic patients also showed significantly improvement in DSST & TMTA. Conclusion:Gardening for chronic schizophrenia patients, especially negative schizophrenic patients can have benefits related to the cognitive improvement, social function, interpersonal relationship, & vocational training.

Brain networks governing the golf swing in professional golfers.

Kim, Jin Hyun,Han, Joung Kyue,Kim, Bung-Nyun,Han, Doug Hyun E. F.N. Spon Ltd 2015 Journal of Sports Sciences Vol.33 No.19

<P>Golf, as with most complex motor skills, requires multiple different brain functions, including attention, motor planning, coordination, calculation of timing, and emotional control. In this study we assessed the correlation between swing components and brain connectivity from the cerebellum to the cerebrum. Ten female golf players and 10 age-matched female controls were recruited. In order to determine swing consistency among participants, the standard deviation (SD) of the mean swing speed time and the SD of the mean swing angle were assessed over 30 swings. Functional brain connectivity was assessed by resting state functional MRI. Pro-golfers showed greater positive left cerebellum connectivity to the occipital lobe, temporal lobe, parietal lobe and both frontal lobes compared to controls. The SD of play scores was positively correlated with the SD of the impact angle. Constant swing speed and back swing angle in professional golfers were associated with functional connectivity (FC) between the cerebellum and parietal and frontal lobes. In addition, the constant impact angle in professional golfers was associated with improved golf scores and additional FC of the thalamus.</P>

Doug Young Chung,Misuk Park,Jin-Woong Cho,Sang-Eun Lee,Kwang-Hyun Han,Jin-Hee Ryu,Seong-Hoon Hyun 한국토양비료학회 2013 한국토양비료학회지 Vol.46 No.2

For organic farming, green manure crops such as leguminous forages and barley have been broadly used to improve soil fertility and soil physical and chemical properties by repeatedly cutting and mulching them directly as winter crop in the field in the rotation. In this investigation we selected 78 agricultural farm corporations as well as individual organic farmhouses related to crop rotation from greenmanure crops to main crops in order to analyze the relationship of cropping system between main crops and green manure crops. The results showed that the green manure crops were divided into two groups as leguminous and nonleguminous crops, representing that those are limited to specific climate and farming systems of regions. Also the 10 or less green manure crops including sudangrass, hairyvetch, italian ryegrass, sorghun, buckwheat, oat, pea, rye, clover, and canola which belong to leguminous crops which are presently cultivated from the organic farmhouses within the rotational crop system. We also confirmed that the major main crops are sweet potato, soybean, corn, tobacco, spinach from usage frequency analyzed by NetMiner H 2.6 which was used to estimate the rotational cropping system among the green manure crops and main crops.

Objective: Coping can be defined as the reactions to harm or distress individuals take to reduce stress. This study aimed to determine how an individual’s temperament and character is correlated with the person’s main coping method. Methods: The Korean version of the Ways of Coping Questionnaire and Temperament and Character Inventory-Revised-Short Version were used to evaluate the coping strategies and temperament and character of 1,035 people. Four hierarchical linear regression analyses with the scores of each coping strategy subscale as a dependent variable were performed. Results: High persistence, cooperativeness, self-transcendence, and low harm avoidance were associated with using a problem-focused coping strategy. Being female, high novelty seeking, reward dependence, and self-transcendence were associated with using a support-seeking coping strategy. High novelty seeking, self-transcendence, and low self-directedness were associated with using emotion-focused coping strategy. Being female, high novelty seeking, persistence, cooperativeness, and self-transcendence were associated with using a hopeful-thinking coping strategy. Conclusion: Our results show that there may be specific personality features guiding what kind of coping strategy an individual might use in a given situation.
