Objectives: This study aimed to investigate the trend in the research on alcoholic liver disease (ALD) using Korean traditional medicine. Methods: This review was conducted using six electronic databases (NDSL, KMBASE, Koreantk, KISS, KISTI, and KoreaMed) with no restrictions in year. The search terms were "alcoholic liver disease", "alcoholic fatty liver", "alcoholic hepatitis", "alcoholic cirrhosis", "herbal medicine", "acupuncture" and "traditional medicine". The searched studies were analyzed according to the type of research. Results: After screening, 37 studies were selected among 552. The types of studies were as follows: 8 in vivo studies, 17 case reports, 7 case series, 1 assessment scale study, 1 randomized controlled trial, and 3 research reviews. The in vivo studies reported the efficacy and its mechanism in the animal phase of single or complex herbal medicine. In the clinical research, interventions such as herbal medicine and acupuncture were most commonly used for ALD treatment. Conclusions: We analyzed the trends in ALD treatment using Korean traditional medicine through this review. The results showed that Korean traditional medicine could be an effective method for ALD treatment. Conducting related in-depth studies, such as well-designed randomized controlled trial based on the results of experimental research, is necessary.

Background: As a physiological function of body, immunity can maintain health by identifying itself and excluding others. With economic development and increasingly fierce social competition, the number of sub-healthy population is gradually increasing, and the most basic problem exposed is human hypoimmunity. Hypoimmunity can be manifested as often feeling tired, catching colds, mental depression, etc. In order to enhance immunity, eating healthy foods with the effect of enhancing immunity may become an effective choice. KRG has pharmacological effects of enhancing immunity. Because the screening and evaluation method of immune population are not unified, there are relatively few KRG immunity tests for sub-health population. It is of great significance to study the effect of KRG on people with hypoimmunity to improve sub-health status. Methods: This was a 180-day, randomized, double-blind, placebo-controlled clinical trial. According to the trial scheme design, 119 qualified subjects were included and randomly divided into the test group taking KRG and the placebo control group. Subjects need to check safety indicators (blood pressure and heart rate, blood routine, liver and kidney function, urine routine and stool routine) and efficacy indicators (main and secondary) inspection at baseline, efficacy indicators inspection during the mid-term of the test (90th days of administration), safety and efficacy indicators inspection after the test (180th days of administration). Results: After the test, the safety indicators of placebo control group and KRG test group were basically within the normal range, and there is no significant difference in fireness score between the two groups. Through follow-up interviews, it was found that the subjects in the test group and the control group had no adverse reactions and allergic reactions such as nausea, flatulence, diarrhea, and abdominal pain during the test period. Self-comparison of the test group, the results of the main efficacy indicators: (1) immune related health scores were significantly improved in the mid-term and after the test (P < 0.01), (2) CD3 and CD4/CD8 increased significantly after the test (P < 0.05), (3) IgG, IgA, IgM and WBC increased significantly in the mid-term and after the test (P < 0.01); the results of the secondary efficacy indicators: (1) TNF-α decreased significantly in the midterm (P < 0.05), IFN-γ decreased significantly in the mid-term (P < 0.01), (2) NK increased significantly in the mid-term and after the test (P < 0.05), (3) monocyte increased significantly in the mid-term and after the test (P < 0.01). Inter-group comparison of the test group and the control group, the results of the main efficacy indicators: (1) immune related health scores were higher than that of the control group in the mid-term and after the test (P < 0.01), (2) IgA of the test group was higher than that of the control group in the mid-term and after the test (P < 0.05); the results of the secondary efficacy indicators: (1) WBC of the test group was higher than that of the control group in the mid-term (P < 0.05); (2) monocytes of the test group were higher than that of the control group in the mid-term and after the test (P < 0.05), neutrophils of the test group were higher than that of the control group in the mid-term (P < 0.05). Conclusion: Taking KRG has no adverse effects on the health of the subjects. According to the standard of clinical trial scheme, the immune related health scores and IgA in the main efficacy indicators were positive, which shows that KRG is helpful in enhancing human immunity.

Objectives: The purpose of this study is to reveal the circumstances under which the cases of harm to health caused by humidifier disinfectant were neglected and show the points where the number of victims and the degree of damage could have been reduced. In addition, it attempts to describe how damage management proceeded immediately after the incident and actually exacerbated the damage. Finally, it explores the unfortunate aspects of the recent trial. By doing so, it attempts to take this as an opportunity to consider whether a tragic event such as the humidifier disinfectant incident could occur in the future. Methods: This study collected and analyzed data on chemical material characteristics related to humidifier disinfectants, data on health effect characteristics, data on related laws and regulations from the Ministry of Environment, data related to the damage investigation by the Korea Environmental Industry and Technology Institute, and current contents. Results: The lack of related systems and laws is the area where the greatest responsibility for the cause of the humidifier disinfectant disaster falls, so it is difficult for the government to escape this responsibility. Establishing a dedicated department to identify the prevalence of certain diseases within the functions of the Health Insurance Review and Assessment Service to monitor health can greatly contribute to the prevention and management of diseases through early detection and management of group outbreaks caused by harmful factors. Humidifier disinfectant damage relief should have been expanded earlier beyond HDLI (humidifier disinfectant lung injury) to include non-specific diseases such as asthma, pneumonia, and interstitial pneumonia. The scope of relief benefits should have also been expanded earlier to include the payment of disability benefits. Fortunately, with the 2020 revision of the Special Act, the conditions for estimating causal relations were eased and individual screening systems such as health impact assessment were reorganized along with the introduction of a rapid screening system. Conclusions: The management system for chemical substances in a country is clearly of paramount importance, and the ministry in charge must have a response system in case of damage to health effects. Administration that looks at the victims' situation from their point of view is needed, and technical countermeasures are required to quickly recognize the prevalence of certain diseases.

Purpose: The purpose of this study was to review studies investigating the effect of bereavement care provided for parents in the neonatal intensive care unit. Methods: We conducted a literature review of databases (MEDLINE, Embase, Cochrane Library, and CINAHL) for studies published in English and four databases (RISS, KISS, NANET, and KoreaMed) for Korean studies. The selection criteria included original articles that evaluated the parents' perceptions or responses to bereavement care provided in the neonatal intensive care unit. Of 889 articles from the initial screening, 66 articles underwent full-text review and five articles were finally selected for analysis. Results: None of the studies was conducted in Korea. Only one study used a randomized control trial design. The forms of bereavement care reviewed included a provision of a memory package, grief information, and emotional and/or social support from peers or health care providers. The effectiveness of bereavement care was measured by including grief, social support, and depression. Conclusion: Bereavement care can be considered to be beneficial for relieving grief reactions and enhancing the personal growth of bereaved parents. Future research should assess the needs of bereaved parents in Korea. Nurses may play a role in developing the bereavement care for parents.

Objectives: The purpose of this clinical trial was to examine the efficacy and safety of electroacupuncture on liver cirrhosis patients suffering from muscle cramps. Methods: Fourteen patients with liver cirrhosis who experienced muscle cramps at least once a week, regardless of cramp location, were enrolled and randomly allocated to an experimental group (n=12) or a control group (n=12). The experimental patients were treated with electroacupuncture at an electrical stimulation frequency of 100 Hz three times a week for four weeks (12 times in total). Muscle cramps were evaluated by a questionnaire that probed subjective symptoms. We analyzed the frequency of muscle cramps 3 times (at screening, 14 th visit, 15 th visit) during 8 weeks. Results: The number of patients with cramps occurring 'more than once a week' was reduced and the proportion of patients decreased in response to electroacupuncture. The number of patients with cramps occurring 'less than once every two weeks' increased and the proportion of patients also increased in response to eletroacupunture. Conclusions: The results of this study suggest that electroacupuncture treatment will be beneficial for improving muscle cramps in patients with liver cirrhosis. Electroacupuncture is considered a safe and efficacious treatment for patients with liver cirrhosis who complain of muscle cramps.

Purpose: The purpose of this study was to investigate the prevalence of depression among school girls in Korea and identify factors influencing the tendency to depression. Methods: A self-report survey was conducted with South Korean middle schoolgirls who were in the 8th and 9th grades. Four hundred and one schoolgirls were included in the study. The instruments utilized in this study were the Center for Epidemiologic Studies - Depression Scale and Social Problem Solving Inventory-Revised. Data were analyzed using descriptive statistics, Pearson correlation and multiple logistic regression with SPSS WIN 14.0 program. Results: The average depression score of the participants was 20.68, which indicates moderate levels of depression. About 35% of the schoolgirls in this study reported a tendency to depression. Significant predictors for depression were 'decreased problem-solving abilities', 'no family members with whom they can discuss their concern', 'decreased satisfaction in relationship with friends', and 'increased negative self-perception of body-image'. Conclusion: The study findings suggest that schoolgirls require special concern regarding the risk of developing depression. Regular depression screening could be beneficial for early detection of depression in schoolgirls and enhancing problem-solving ability could be considered as an effective strategy to reduce the risk of depression among schoolgirls.

Genetic diversity of 47 East-Asian vegetable soybean was characterized by means of agro-morphological traits and RAPD markers. A field trial was conducted to evaluate 14 agro-morphological traits. To study RAPD-based DNA analysis, a total of sixty 10-mer random primers were screened. Of these, 23 polymorphic markers in 16 varieties used for screening. Among 207 markers amplified, 48 were polymorphic for at least one pairwise comparison within the 47 varieties. A higher differentiation level between varieties was observed by using RAPD markers compared to morphological markers. Correspondence analysis using both types of marker showed that RAPD data could fully discriminate between all varieties, whereas morphological markers could not achieve a complete discrimination. Genetic distances between the varieties were estimated from simple matching coefficients, ranged from 0.0 to 0.640 with an average of 0.295$\pm$0.131 for morphological traits and 0.042 to 0.625 with an average of 0.336$\pm$0.099 for RAPD data, respectively. Cluster analysis based on genetic dissimilarity of these varieties gave rise to 4 distinct groups. The clustering results based on RAPDs did not match with those based on morphological traits. Geographical distribution of most varieties in each of the groups were not well defined. The results suggested that the level of genetic diversity within this group of East-Asian vegetable soybean varieties was sufficient for a breeding program and can be used to establish genetic relationships among them with unknown or unrelated pedigrees.

Anti-inflammatory factor(AIF) is a water soluble extract of three herbs, Panax notoginseng(Burk.) F. H. Chen, Rehmannia glutinosa Libosch and Eleutherococcus senticosus. The present study aimed to investigate the safety and efficacy of herb extracts, AIF, on Korean knee osteoarthritis patients for six weeks. Fifty seven patients with knee osteoarthritis, ranging from 43 to 73 years of age, who fulfilled the "American College of Rheumatology"(ACR) classification of idiopathic osteoarthritis of knee and radiographic criteria were randomly selected and enrolled for the study. After initial screening and resting period, two capsules each of AIF(Each capsule contains; 400 mg) and similar identical placebo were administered twice a day to both groups. Pain intensity at second, fourth, and sixth weeks of study as well as one week after discontinuation of drugs was assessed by using 100 mm visual analogue scale(VAS). Changes in the Korean version of the Western Ontario and McMaster Universities(K-WOMAC) index score were compared at the initiation and completion of the study. VAS assessed by patients were significantly reduced(at visit 2; $54.64{\pm}14.72$, at visit 4, $37.32{\pm}16.58$, p<0.001) after AIF administration. Results showed an improvement in the physical function of K-WOMAC scale which was significantly higher(p=0.013) in AIF than placebo group, and decreases of total K-WOMAC score were also significantly higher(p=0.030) in AIF groups than placebo group. No serious adverse effect was observed, and there was no difference in incidence of adverse effect between AIF and placebo groups. In this population of Korean patients with knee osteoarthritis, AIF was found to be safe, tolerable and effective for symptomatic improvement of pain and physical function.

본 연구에서는 청소년영화제의 형성과정과 그 과정에 영향을 미친 요인에 대해 살펴보고자 한다. 청소년영화제는 어느 날 갑자기 등장한 것이 아니다. 이미 1980년대부터 시민단체를 중심으로 미디어교육에 대한 다양한 시도가 있었으며, 1997년부터 2001년에 이르는 시기 동안 주요 청소년영화제들이 개최되어 영화제의 기틀을 잡게 되었다. 이후 발전을 거듭하던 청소년영화제는 2008년에 이르러 온라인 상영을 실시하는 등 변화를 맞이하게 되었으며, HD캠코더와 스마트폰의 등장 등 급격히 변화하고 있는 영상산업과 문화적 흐름에 호응하며 현재에 이르고 있다. 이러한 청소년영화제의 형성과정에 영향을 미친 요인을 크게 두 개의 영역으로 나누어 살펴보면 다음과 같다. 우선 경제 사회적 요인으로 시민단체의 성장, 영상기술의 발전과 대중화, IMF 구제금융시대 등으로 설명할 수 있으며, 문화 교육적 요인으로는 영상문화의 융성, 대학입시와 수상실적으로 나눌 수 있다. 이렇게 다양한 영향 속에서 청소년영화제는 발전하였으며, 이러한 형성과정 속에서 한국 사회의 여러 단면을 들여다 볼 수 있다.
