Objective : The purpose of this study was to investigate the longitudinal trajectories of life satisfaction, loneliness, and depression and to identify the factors that influence these trajectories in North Korean Defectors (NKD). Methods : NKD (n=300) who registered in the multi-regional adaptation center (Hana Center), within three years of settling in South Korea, were recruited into this study. Life satisfaction, loneliness, and depression were assessed with self-report questionnaires over a period of 4 years (7 waves of data). Latent growth modeling was conducted to assess the changes in life satisfaction, loneliness, and depression. Results : Findings from both unconditional and conditional models (with gender, South Korea settlement age, household income, marital status, and PTSD at wave 1) indicated a linear increase in loneliness and depression, and a linear decrease in life satisfaction over the 4-year period. In the conditional model, gender predicted the intercept of life satisfaction and depression. In addition, PTSD predicted the intercept of life satisfaction, loneliness, and depression and slope of depression. Conclusion : Our finding suggests that the mental health of NKD tends to deteriorate over time after settling in South Korea. Therefore, continuous support is necessary for their successful adaptation to the South Korean Society.

This study was to find out whether there were differences in the levels of depressions between positive and negative schizophrenics. This research was derived from the fact that negative schizophrenics show higher levels of depression than positive schizophrenics. This study also examined the levels of psychomotor dysfunction in positive and negative schizophrenics. For this study, there were 453 subjects. They consisted of 119 positive schizophrenics, 122 negative schizophrenics and 212 normal people. They were asked to complete Zung's Self-Rating Depression Scale(SDS) and to perform one subtest, Digit Symbol of KWIS(Korean Wechsler Intelligence Scale). Subjects' levels of depression were measured by the SDS. the level of psychomotor dysfunction was measured by Digit Symbol subtest of Korean Wechsler Intelligence Scale. ANOV A and Duncan's multiple comparison analysis were used to examine whether there were differences of depression and psychomotor dysfunction among the normal people, positive and negative schizophrenics. The results were as follows: It was found that the depression level was higher in the negative schizophrenic patients than positive schizophrenic patients. Levels of depression were significantly higher in negative schizophrenics than positive schizophrenics. Psychomotor retardation symptom was the most effective variable that discriminates between the normals and the schizophrenics. And it would be concluded that the psychomotor dysfunction was more severe in negative schizophrenics than positive schizophrenics.

Many patients with dizziness present with a symptom pattern that does not reveal the cause by neurotologic diagnostic approaches. In such cases, the physician frequently diagnoses psychogenic dizziness. Psychogenic dizziness is not characterized by true vertigo, and occurs in combination with other psychiatric symptom cluster. One out of two to four patients with dizziness are psychogenic dizziness. But there are few concern about this including clinical practice and study in Korea. I wrote this paper to increase concerning and attending to this for psychiatrists in Korea. I reviewed etiology including biological and psychological relations between dizziness and psychiatric disorder(especially anxiety), diagnostic approaches of, characteristics of dizziness of various psychiatric disorders related to, and the treatment of psychogenic dizziness. I also briefly reviewed the central and peripheral dizziness for psychiatrists. I suggest psychiatrists and clinicians in the psychosomatic field in Korea to acknowledge, concern, and attend to psychogenic dizziness. In turn, it will be helpful to well treat the patients with psychogenic dizziness.

Recently, research on social entrepreneurship, which simultaneously pursues social value creation and economic sustainability has increased rapidly. Researchers conducted several empirical studies, noting that social entrepreneurship is a major factor in improving the performance of social enterprises. However, most previous studies usually have limitations in measuring the performance of social enterprises based on the subjective perception of entrepreneurs, which implies the limitations of the common method bias. In addition, there is a lack of empirical evidence that can explain the specific process in which the personal characteristic of an entrepreneur, social entrepreneurship, affects the achievement of dual goals. Therefore, this study empirically investigates the effect of social entrepreneurship on performance increasing the objectivity of performance measurement and including blended value orientation(BVO), a characteristic of viewing social and economic performance as a single thing. The purpose of the study is to verify the effect of social entrepreneurship and BVO on the social and economic performance of social enterprises. We conducted regression analysis using the results of the perception survey of social enterprises in South Korea and objective performance data. As a result, risk-taking, a sub-factor of social entrepreneurship, had a positive effect on economic and social performance at a significant level. In addition, it was confirmed that social entrepreneurship improves BVO, and it affects social performance. Therefore, this study found that social entrepreneurship and BVO have a discriminatory effect on economic and social performance, respectively. This study is meaningful in that it attempted to overcome the common method bias as measuring subjectivity performance.

Objectives:Previous studies have suggested that S100B protein play an important role in the pathogenesis and progress of schizophrenia. In the present study, we evaluate the serum levels of S100B in the patients with schizophrenia, and compare them with those of healthy controls. Method:The serum S100B levels were measured by lectrochemiluminescence immunoassay in 21 schizophrenic patients (8 males, 13 females) and 27 normal controls(11 males, 16 females). The Positive and Negative Syndrome Scale(PANSS) was used to evaluate the symptoms of the patients with schizophrenia, and the correlation between PANSS subscale scores and serum S100B levels was examined. Results:No significant difference was found between the serum S100B levels of the schizophrenic patients($0.074{\pm}0.039$ng/ml) and those of the normal controls($0.072{\pm}0.030$ng/ml)(p=0.925). Correlationships between the high serum S100B level with high negative symptom scores(p=0.065) or with the low positive symptom scores(p=0.080) did not exist. Conclusion:The relation between serum S100B level and schizophrenia was not found in the present study. However, to confirm this result, further studies, such as measurement of S100 protein level in CSF, postmortem study, long-term follow-up study, and studies with other neurotrophic proteins are needed.

Objectives:There is increasing evidence that the cerebellum plays an important role in cognition and psychiatric symptoms as well as motor coordination. The concept of cognitive dysmetria has been making cerebellar function in schizophrenia the focus of current studies. In other words, disruption in the corticocerebellum-thalamic -cortical circuit could lead to disordered cognition and clinical symptoms of schizophrenia. The purposes of this study were to determine cerebellar dysfunction in male schizophrenic patients semiquantitatively with ICARS and to investigate the clinical and cognitive correlates of ICARS in patients. Methods:We compared the scores of cerebellar neurologic sign using ICARS in 47 male patients with a DSM-IV-TR diagnosis of schizophrenia with 30 gender and age-matched healthy control subjects. The semiquantitative 100-point ICARS consists of 19 items divided into 4 unequally weighted subscores:posture and gait disturbances, kinetic functions, speech disorders and oculomotor disorders. All subjects were also assessed with cognitive function test. Cognitive functions were evaluated by Korean-Mini Mental Status Examination (K-MMSE), Verbal fluency test, and Clock drawing test. The patients were administered Korea version of Positive and Negative Symptom Scale(K-PANSS) to assess the symptom severity. Results:Schizophrenic patients had significantly higher scores on the ICARS than control subjects with posture and gait disturbances, kinetic functions, and oculomotor disorders. They also showed more significant impairments in cognitive function tests than control subjects. There was a significant correlation between ICARS and negative symptoms of patients. In cognitive function test, Clock drawing test was significantly associated with negative symptoms. In addition, Clock drawing test was negatively correlated with the total score of ICARS. Conclusion:In this study, we confirmed that schizophrenic patients have significant impairments in cognitive and cerebellar function, and that those were related with negative symptoms of schizophrenic patients. These results support a role of the cerebellum in schizophrenia. It is meaningful that we used a structured, and reliable procedure for rating neurological soft signs, ICARS. We hope that future prospective studies using a similar design help that rate of neurological sign should have been visible with the progression of illness.
