육군 지상작전사령부는 4차 산업혁명 기술의 고도화와 변화된 안보환경에 따른 미래 지상작전 승리를 도모하기 위해 국방 분야에 인공지능(AI)을 적용하기 위한 다양한 방법론을 연구하였다. 인공지능을 적용하여 지상작전을 혁신하기 위한 추진전략과 과제를 개발하는 방법으로 PEST-7S-SWOT 방법론을 적용하였다. PEST-7S-SWOT 방법은 3단계로 적용하여 1단계는 외부환경요인 분석단계로 PEST 방법을 적용하여 외부환경 영향요소를 기회와 위험요인으로 도출하고, 2단계는 내부환경요인 분석단계로 7S 방법을 적용하여 조직의 현 상태분석을 통해 강점과 약점요인을 도출할 수 있었다. 마지막 3단계는 SWOT 분석을 적용하는 단계로 1단계의 기회 및 위험요인과 2단계의 강점과 약점요인을 기준으로 대응전략을 수립하여 추진전략과 과제를 도출하였다. 본 연구를 통해 지상작전사령부의 AI 발전을 위해 정책 및 제도 발전, 조직 및 편성 강화, AI 발전기반 구축, 전문성 및 능력 제고 등 4개 분야의 AI 추진전략과 11개 추진과제를 도출하였다. Ground Operations Command (GOC) has studied various methods using artificial intelligence (AI) in order to accomplish ground missions more effectively and to strongly respond to variable strategic situations with advancements in fourth industrial revolution technology. As the result of various literature reviews, PEST-7S-SWOT is considered the most appropriate methodology for promoting strategies and for task development. These procedures consist of three stages. Phase 1 is analysis of external environmental factors from applying PEST procedures. We analyzed external environmental factors to determine opportunities and risk factors. Phase 2 is the analysis of internal environmental factors from applying 7S strategies. We analyzed the current state of an organization to find strengths and weaknesses. Phase 3 is SWOT analysis. It is based on the opportunities and risk factors from Phase 1 and the strength and weakness factors from Phase 2. We derive promotional strategies and tasks through SWOT analysis. In this study, four strategies and 11 tasks were derived for GOC AI systems. Those are promotion of policies and systems, reinforcing organizations, building an AI base, increasing expertise and capabilities, and validating PEST-7S-SWOT methodologies.

JaeMin Kim,KyungYeol Bae,HeeJu Kang,SungWan Kim,IlSeon Shin,YoungJoon Hong,JuHan Kim,HeeYoung Shin,YoungKeun Ahn,JongKeun Kim,MyungHo Jeong,JinSang Yoon 대한신경정신의학회 2014 PSYCHIATRY INVESTIGATION Vol.11 No.1

Depression is common after acute coronary syndrome (ACS), adversely affecting cardiac course and prognosis. There have been only a few evidence-based treatment options for depression in ACS. Accordingly, we planned the Korean Depression in ACS (K-DEPACS) study, which investigated depressive disorders in patients with ACS using a naturalistic prospective design, and the Escitalopram for DEPACS (EsDEPACS) trial, which assessed the efficacy and safety of escitalopram for treating major or minor depression in patients with ACS. Participants in the K-DEPACS study were consecutively recruited from patients with ACS who were recently hospitalized at Chonnam National University Hospital, Gwangju, South Korea. Diagnoses were confirmed by coronary angiography from 2005. Data on depressive and cardiovascular characteristics were obtained at 2 weeks, 3 months, 12 months, and every 6 months thereafter following the index ACS admission. The K-DEPACS participants who met the DSM-IV criteria for major or minor depressive disorder were randomly assigned to groups in the 24-week, double-blind, placebo-controlled EsDEPACS trial beginning in 2007. The outcome of treatments for depressive and other psychiatric symptoms, issues related to safety, including general adversity, and cardiovascular factors were assessed. The K-DEPACS study can significantly contribute to research on the complex relationships between depression and ACS. The results of the EsDEPACS trial provide an additional treatment option for clinicians treating these patients.

HeeJu Kang,KyungYeol Bae,SungWan Kim,HeeYoung Shin,IlSeon Shin,JinSang Yoon,JaeMin Kim 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.3

Objective-This study aimed to investigate the longitudinal effects of anxiety, depression, and their comorbidity on physical disorders and disability in an elderly Korean population. Methods-In total, 1,204 community-dwelling elders were evaluated at baseline, and of these 909 (75%) were re-assessed two years later. Anxiety and depression were identified at baseline using questions from the community version of the Geriatric Mental State diagnostic schedule (GMS-B3). Participants were assessed for functional disability and for 11 physical disorders both at baseline and at follow-up. Results-Anxiety alone was associated with the incidence of heart disease, depression alone with the incidence of asthma, and comorbid anxiety and depression with incidence of eyesight problem, persistent cough, asthma, hypertension, heart disease, and gastrointestinal problems. Comorbid anxiety and depression were associated with an increase in the number of physical disorders and the degree of disability during the two-year follow-up, compared to anxiety or depression alone or the absence of anxiety or depression. Conclusion-Anxiety, depression, and particularly their comorbidity should be assessed in the elderly population considering their longitudinal effects on physical disorders and disability. Future study is required to determine whether interventions aimed at these disorders can mitigate their impacts.

HeeJu Kang,KyungYeol Bae,SungWan Kim,IlSeon Shin,YoungJoon Hong,Youngkeun Ahn,MyungHo Jeong,SungWoo Park,YoungHoon Kim,JinSang Yoon,JaeMin Kim 대한신경정신의학회 2016 PSYCHIATRY INVESTIGATION Vol.13 No.1

Genes related to serotonin are associated with responses to treatment for depression. We examined associations between the serotonin transporter (5-HTT) and serotonin 2a receptor (5-HTR2a) genes and responses to treatment for depressive disorders in acute coronary syndrome (ACS). A total of 255 patients who met the DSM-IV major or minor depressive disorder and recently developed ACS were randomly assigned to the escitalopram (n=127) or placebo (n=128) group in this 24-week double-blind trial (ClinicalTrial.gov identifier: NCT00419471). Remission was defined as a Hamilton Rating Scale for Depression (HAMD) score ≤7. Assays were performed for the 5-HTTLPR, STin2 VNTR, 5-HTR2a 102T/C, and 5-HTR2a 1438A/G genotypes. Escitalopram was superior to placebo for treating depressive disorder with ACS but there were no significant associations between serotonergic genes and treatment responses even when considering ACS severity. The effect of escitalopram was independent of 5-HTT and 5-HTR2a polymorphisms.

JuWan Kim,HeeJu Kang,KyungYeol Bae,SungWan Kim,HyunKyong Oh,MinGon Kim,JaeMin Kim 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.4

Severe physical injury is a leading cause of posttraumatic syndrome (PTS). This is to develop a biomarker-based diagnostic algorithm for posttraumatic syndrome (BioPTS) study. This is a 2-year longitudinal cohort study assessing patients who were hospitalized beginning in 2015 at Chonnam National University Hospital in Gwangju, Korea, after experiencing severe physical injuries. Baseline evaluations were made during the acute phase (within 1 month) of the physical injury and included extensive information on sociodemographic and clinical variables as well as a list of biomarkers. All participants will be followed up for 2 years, and the diagnostic and predictive validities of various biomarkers for PTS will be estimated. The BioPTS study will develop the most accurate models for the diagnosis and prediction of PTS, and will contribute to existing research regarding the complex relationships between severe physical injury and psychological issues.

Objective-Stroke is associated with significant long-term morbidity and poor quality of life (QOL). Depression is one of the most common complications after stroke and has been associated with QOL cross-sectionally. We investigated the longitudinal impact of depression in the acute phase of stroke on QOL 1 year after stroke. Methods-In total, 423 patients were evaluated 2 weeks after stroke, and 288 (68%) were followed 1 year later. QOL was assessed using the World Health Organization Quality of Life-Abbreviated form (WHOQOL-BREF) at baseline and follow-up. Depression was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders-IV criteria; demographic and clinical characteristics data, including stroke severity, were obtained at baseline. The longitudinal associations of post-stroke depression (PSD) at baseline with QOL across two evaluation points were assessed using a repeated-measures analysis of variance. Results-The WHOQOL-BREF scores were significantly and persistently lower 1 year after stroke in patients with PSD at baseline compared with those without PSD at baseline independent of demographic and clinical characteristics, including stroke severity. Conclusion-PSD in the acute phase of stroke is an independent predictor of QOL in both the acute and chronic phases of stroke. Our findings underscore the importance of evaluating depression in the acute phase of stroke.

Suelin Yoon,JaeMin Kim,HeeJu Kang,KyungYeol Bae,SungWan Kim,IlSeon Shin,JinSang Yoon 대한신경정신의학회 2015 PSYCHIATRY INVESTIGATION Vol.12 No.4

Objective-Previous studies reported an association between pulmonary function and cognitive function. However, not much has been investigated in this regard concerning dementia in a community population, taking depression into account. We aimed to examine the associations of pulmonary function with dementia and depression in a community-dwelling elderly population. Methods-A total of 1,038 participants were evaluated for dementia and depression using the Korean version of the Geriatric Mental State Schedule B3 (GMS B3-K), the Community Screening Interview for Dementia-Korean version (CSID-K) and a modified 10-item Word List Learning from the Consortium to Establish a Registry of Alzheimer’s Disease (CERAD). Pulmonary function was measured as forced expiratory volume in 1 s (FEV1) from a forced expiratory maneuver. Results-Prevalence rates of dementia and depression were 11.0% and 10.4%, respectively. Individuals who were diagnosed with dementia manifested a lower mean FEV1, as compared to those without dementia after adjusting for potential confounders, including disability and depression [OR=1.34 (1.05–1.72)]. Following gender-stratified analysis, the association was only statistically significant in women [OR=1.40 (1.04–1.89)]. The association between depression and mean FEV1 was less significant compared to dementia [OR=1.32 (1.10–1.58)]. However, the association was no longer significant after adjusting for age and years of education. No association was significant in the gender-stratified analysis. Conclusion-Decreased pulmonary function was associated with dementia status only in an older female Korean population. Pulmonary function and depression were not significantly associated in either gender.

JuYeon Lee,SungWan Kim,HeeJu Kang,SeonYoung Kim,KyungYeol Bae,JaeMin Kim,IlSeon Shin,JinSang Yoon 대한신경정신의학회 2017 PSYCHIATRY INVESTIGATION Vol.14 No.6

We investigated the association between problematic internet use (PIU) and post-traumatic stress disorder (PTSD) symptoms in children and adolescents in South Korea. A cross-sectional survey was administered to community students who attended primary, secondary, and high schools in the Jindo area 1–2.5 months after the Sewol ferry disaster. Of the 1,744 respondents, 392 students who were exposed to the disaster, witnessing the rescue work directly, were evaluated. PTSD symptoms were measured using the University of California Los Angeles Post-traumatic Stress Disorder Reaction Index (UCLA PTSD-RI). The severity of impairment caused by excessive internet use was evaluated using Young’s Internet Addiction Test. The Center for Epidemiological Studies Depression Scale (CES-D) and State Anxiety Inventory for Children (SAIC) were also used. Logistic regression analysis revealed that PIU was significantly and independently associated with a high level of PTSD symptoms. Our findings suggest that children and adolescents with PIU require intensive follow-up and special care to prevent the development of PTSD symptoms following a disaster.

Objective We aim to present a clinical guideline for the diagnosis and treatment of insomnia in adults by reviewing and integrating existing clinical guidelines. The purpose of this guideline is to assist clinicians who perform evidence-based insomnia treatment.Methods We selected literature that may be appropriate for use in guideline development from evidence-based practice guidelines that have been issued by an academic or governmental institution within the last five years. The core question of this guideline was made in sentence form including Patient/Problem, Intervention, Comparison, Outcome (PICO) elements. After searching PubMed, EMBASE, and medical guideline issuing agencies, three guidelines were judged to be the most appropriately reviewed, up-to-date, and from trusted sources.Results The Appraisal of Guidelines for Research and Evaluation (AGREE) II tool was used to evaluate the quality of the three clinical guidelines. The final outcome of the guideline development process is a total of 15 recommendations that report the strength of the recommendation, the quality of evidence, a summary of content, and considerations in applying the recommendation.Conclusion It is vital for clinical guidelines for insomnia to be developed and continually updated in order to provide more accurate evidence-based treatments to patients.
