The Cooperative Engagement Capability (CEC) System produces a synergy between the sensors and shooters that are used on various platforms by integrating them. Even the US Navy has been recently adopting the CEC system that maximizes the effectiveness of the air defense operations by efficiently coordinating the dispersed air defense assets. The Navy of other countries are conducting research studies on the theory and application methods for the CEC system. The ROK Navy has limited air defense capabilities due to its independent weapons systems on battle ships. Therefore, the ROK Navy is currently going through a phase where research on proving the validity of building the CEC system because it will provide a way to overcome the limit of the platform based air defense capability. In this study, our goal is to propose methods that maximize the air defense capability of ROK Navy, identify the available assets for constructing the CEC system, and estimate effects of the CEC system when it is applied to the naval operations. In addition, we will provide a simple model that was developed to estimate these effects and a case study with virtual data to demonstrate the effects of the system when it is applied to the naval operations. The research result of this study will provide a way for building the basis of the Korean CEC system.

연구목적 이 연구는 만성 조현병 조현병 환자에서 대사증후군과 인지기능과의 연관성을 알아보기 위해 시행하였다. 방 법 일 병원에서 입원중인 만성 조현병 환자 105명(대사증후군 40명, 비대사증후군 65명)을 대상으로 A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet(CERAD-K)의 인지기능 검사 항목들을 시행하였다. 결 과 대사증후군에 이환된 만성 조현병 환자들에서 구성실행 검사 항목에서 대사증후군에 이환되지 않은 군에 비해 유의하게 낮은 점수를 나타냈으며, 그 외 다른 검사항목에서는 차이점이 나타나지 않았다. 결 론 만성 조현병 환자에서 대사증후군이 구성실행 검사 항목에서의 인지기능 저하를 나타내었다. 조현병 환자에서 대사증후군의 적절한 치료가 필요할 것이며 향후 장기추적연구가 필요할 것으로 보인다. Objectives : The aim of this study was to investigate the relationship between metabolic syndrome and cognitive functions among chronic schizophrenia patients. Methods : The survey participants were 105(40 metabolic syndrome and 65 non-metabolic syndrome) chronic schizophrenia patients at Yang-san Hospital. Each score of cognitive test(A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet, stroop test), Positive and Negative Syndrome Scale, Hamilton rating scale for Depression were assessed. Statistical analysis of the relationship between various tests of A Korean version of the Consortium to Establish a Registry for Alzheimer's Disease Assessment Packet and metabolic syndrome were performed using ANCOVA and logistic regression. Results : Schizophrenia patients with lower score on construction praxia were likely to be included in Metabolic syndrome group. However, there were no significant relationships in other tests between the two groups. Conclusions : This study found metabolic syndrome caused cognitive decline in chronic schizophrenia patients, especially Construction praxia. This study could be a basis to show metabolic syndrome has to be treated appropriately in schizophrenia patients and suggests the necessity of following longitudinal designed study.

Objective:It investigated the tendency of the increase of elderly patients in a psychiatric hospital. In this regard, it examined whether the number of patients with outpatient consultant, discharge, medical diseases, and neurocognitive disorder increased or not. Methods:It retrospectively reviewed inpatient medical records for the years 2008, 2011, 2014, 2017. To investigate the changes of elderly patients admitted to psychiatry, it examined the changes of patients who are older than 50 or 60 years in addition to the people who are older than 65 years. It analyzed diagnosis, discharge, medical diseases, and outpatient consultant of the three groups respectively. Results:It confirmed that the number of elderly patients who are older than 50, 60, and 65 years has increased in mental hospital for 10 years. There was a significant increase in the number of neurocognitive disorder patients, the ratio of consultant outpatient, and the mean number of outpatient consultant. Diabetes increased in all three groups. Especially it has significantly increased for patients who are older than 50 and 60 years. In the case of patients discharged due to transfer, the number of patients increased in all three groups but it was statistically significant for the patients who are older than 50 years. Conclusion:The study shows that the number of elderly patients increased with the trend of aging society. In relation to this, the rate of outpatient consultant and discharge, including diabetic and dementia patients, also increased. Therefore, if the mental health department provides a system to manage the elderly ward or nursing ward to respond to the increase of elderly patients, or to manage the accompanying chronic diseases such as diabetes and its complications, it could solve the inconvenience of patients due to the consultation outside a hospital or discharge.

Objectives : The purpose of this study is to investigate personality traits, investigate differences in onset times between the sexes, and compare schizophrenic patients with alcoholic patients using TCI. And we examined the correlation between TCI and drinking characteristics, and TCI and motivational status for abstinence. Methods : We enrolled 169 alcohol de-pendent patients (118 males, 51 females) by DSM-IV criteria, and 86 stable schizophrenic patients (42 males, 44 females) for the control group. We used TCI, SCL-90, AUI, URICA as a self reported questionnaire. We compared the score of those questionnaires of the early onset group with that of the late onset group in the alcohol dependent group. Results: 1) The mean values of Novelty Seeking (NS) and Reward Dependence (RD) were significantly higher in the alcohol dependent group than in the control group (schizophrenic patients). 2) In the alcohol dependent group, the early onset group had significantly higher Novelty Seeking (NS) and Self Directedness (SD) but lower Harm Avoidance (HA) than the late onset group. 3) The mean value of Novelty Seeking (NS) in female alcohol dependent patients was significantly higher than in male patients in the early onset group, and the mean value of NS in females was significantly lower than in males in the late onset group. 4) The mean value of Harm Avoidance (HA) was higher in female alcohol de-pendent patients than in the male patients group, and the late on-set group had a higher mean value than the early onset group. 5) Harm Avoidance (HA) had negative correlation with ‘anxiety related to drinking’, and Reward Dependence (RD) and Cooperativeness (CO) had positive correlation with ‘acknowledgement and awareness of use problem’. 6) The patients with lower Reward Dependence (RD) and Cooperativeness (CO) were included in the lower motivation group. Conclusion : The alcohol dependent patient group was more impulsive and intemperate, and had a stronger tendency to pursue new things than the schizophrenic patient group. Especially, female alcohol dependent patients had a higher tendency to seek stimulation, so they drink alcohol more impulsively, resulting in higher risks of acquiring alcohol-dependence problems earlier than the male alcohol dependent patient group. On the other hand, females who had anxiety and higher avoidant tendency acquired alcohol dependence later in life. Reward Dependence (RD) and Cooperativeness (CO) were related with patient’s motivation, so it will affect the prognosis of the treatment.

Objectives : The therapeutic approach for a patient with alcohol dependence should match the patient’s characteristics, determined before treatment initiation. However, most services provided for these patient by hospitals and community counsel-ing centers do not usually differ. We conducted this study to evaluate drinking history and cognitive function of patients with-in each institution, in order to design an effective treatment ap-proach. Methods : Alcohol-dependent patients visiting at a com-munity counseling center and a university hospital were included as study subjects and investigated for demographics and drink-ing history. In addition, we performed neuropsychological test-ing to evaluate IQ, memory, and executive function. Results :TSignificant differences were found in terms of duration of drink-ing and blackout detected for drinking and blackout duration between the patients visiting at community counseling center and a university hospital (drinking duration, 22.74±13.47 vs. 33.14± 13.75, p<0.05 and blackout duration, 9.79±9.41 vs. 18.43±13.21, p<0.05). Patients visiting at community counseling center start-ed drinking at an earlier age than the patients visiting at univer-sity hospital (11% vs. 32%, p<0.10). The patients visiting a com-munity counseling center had an executive function disability for IQ (χ=2.95, p=0.08). In addition, the patients visiting a com-munity counseling center started drinking at an earlier age than the patients visiting a university hospital (11% vs. 32%, p<0.10). Conclusion : These findings suggested that the patients visiting at a community counseling center started drinking earlier, had been drinking longer, and had poorer cognitive function than patients visiting at university hospital. Therefore, different ther-apeutic services should be offered based on these characteristics.

Objectives : Psychotic Symptom Rating Scale (PSYRATS) is an assessment tool to measure the seventy of different dimen-sions of auditory hallucinations and delusions. The reliability and validity of the Korean version of PSYRATS (K-PSYRATS)were examined in Korean patients with major psychosis. Methods : The inter-rater reliability of the K-PSYRATS was determined from the videotaped interviews of the five Schizoph-renic patients. To measure validity and internal consistency reliability, the 109 patients with auditory hallucinations or delusions were assessed using the K-PSYRATS, Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression-Se-verity (CGI-S) scale. Results : K-PSYRATS was found to have excellent inter-rater reliability (intra-class correlation coefficient of auditory haliu-cination=0.81, P<.001, intm-class correlation coefficient ofde1usion=0.97, P<.001) and internal consistency reliability (Cron-bach's a of auditory hallucination =0.77, Cronbach's α of delusion =0.76). Significant correlation was found between K-PSY-RATS and positive syndrome subscale of PANSS and CGI. Conclusion : K-PSYRATS is a useful assessment instrument for psychotic symptoms in Korea.
