This review examined recently published (July 2014 to June 2017), randomized controlled trials (RCTs) which investigated the safety and effectiveness of combined Korean medicine/complementary alternative medicine (CAM) and Western medicine, to indicate the direction for integrative medical practice. The Korean Medicine Convergence Research Information Center evidence-based medicine database (KMCRIC EBM DB) was used to retrieve relevant RCTs indexed in the last 3 years. Study design, country, sample size, disease/condition with the Korean Standard Classification of Diseases code, interventions, direction of outcomes, and adverse events were extracted and summarized. A total of 93 RCTs were included in this review. Acupuncture/moxibustion was the most commonly used intervention (n = 47; 51%), and 19% (n = 18) of the studies treated musculoskeletal disorders, followed by circulatory disorders (n = 16; 17%), and mental and behavioral disorders (n = 9; 10%). Integrative treatment was reported as more effective than monotherapy in approximately 83% of these studies. Adverse events were poorly reported in most studies. This review suggests that integrative treatments are feasible, effective, and safe for various diseases/conditions, based on the evidence from recently published RCTs. Future studies on integrative healthcare are warranted.

원형 콘크리트 충전 강관 (CFT)은 강관과 콘크리트 내부채움재로 이루어진 합성구조로 급속 시공이 가능하고 치수 대비 강도의 효율성이 좋아 교량의 교각이나 건축물의 기둥으로 사용되고 있다. CFT에 대한 실험적 연구는 지난 수년간 꾸준히 연구되어 왔지만 이러한 실험 연구만으로 CFT의 거동을 파악하기는 충분하지 않다. 따라서, CFT의 실험 연구를 보완하고 보다 다양한 제원 및 하중 조건을 고려하여 CFT의 구조 거동을 파악하기 위해서는 수치해석 모델이 필요하다. 본 연구는 CFT의 비선형 유한 요소 해석 기법을 개발하는데 목표가 있다. 개발된 CFT의 유한 요소 해석 모델 기법은 다양한 하중이 작용하는 실험 결과들과 비교하여 그 타당성을 입증하였으며, 제안된 유한 요소 해석 모델은 CFT의 구속 효과 및 CFT의 구조 거동을 잘 모사할 수 있었다.

Purpose: The purpose of this study was to determine the effects of auricular acupressure on menstrual pain, difficulties in daily life, negative feelings and autonomic nervous responses among college students. Methods: A Randomized Controlled Trial design was used. The treatment group A (n=12) receivedauricular acupressure therapy on the first or second day of their menstrual period. Treatment group B (n=18) regularly received an auricular acupressure therapy once a week for a month. The control group (n=19) received no auricular acupressure therapy. An independent t-test was used to examine pre-post test differences in the group. The ANOVA and Scheffe test were used to examine pre-post test differences among the group. Results: Subjects in treatment group A showed significantly less menstrual pain, difficulties in daily life, and negative feelings than the control group did. The participants in treatment group B also showed significantly less difficulties in daily life and negative feelings than the control group. Conclusion: The findings support that auricular acupressure therapy on menstrual periods is effective in controlling menstrual pain, difficulties in daily life, and negative feelings. As the method is simple, it would be useful for female students to learn to use this method to alleviate the symptoms related to menstruation through self care.

Purpose: This study was done to provide support material to traditional nursing interventions through investigation of the effect of Auricular acupressure therapy for female staff in the hospital who have dysmenorrhea but cannot be absent from work even with severe symptoms affecting their work and therefore cannot get proper pain management. Method: The participants in this study were 62 women were working in the G-university hospital in Jin-ju, assigned to experimental (30) and 32 control groups (32). The study method was a quasi-experimental, nonequivalent control group non-synchronized design. The experimental group received acupressure treatment (a pin was attached to tape) on the special stimulation points in the inside of the ear, 5 times for 5 seconds, morning, afternoon, and night. Tape without the pressure pin was applied to the same points for women in the control group to evaluate placebo effect. Data were collected from May to November 2007 and were analyzed using SPSS PC+ 12 version. Descriptive statistics, t-test, $x^2-test$, Fisher's exact test, paired t-test, were used to analyze the data. Results: The experimental group showed a significant decrease in dysmenorrhea compared to the control group (t=-2.743, p<.01). In the sub-part, the experimental group showed menstruation related pain (t=-3.726, p<.01), menstruation related to behavioral change (t=-2.421, p<.05) and symptoms however, there was no significant difference related to attention deficit, water retention, and negative image. Conclusion: Application of auricular acupressure therapy was approved for this study and although auricular acupressure therapy was not effective for all of the symptoms, it was effective for dysmenorrhea.

The purpose of this study is to look at the case of the German compensation system for farmers' accidents and to build a basic scheme in our country's compensation system for farmers' accidents. When you view examples of Germany, the social insurance scheme for farmers accidents in korea should be design as an independent institution from the existing industrial accident insurance, and it comes to relationships with other social insurance system, preferably with complementary personalities. A general rule of the compensation system applies to all farmers in principle but the coverage limits part-time farmers. Financial burden consists of the mix of insurance premium and state aid. The type and level of benefits is similar to the current industrial accident insurance, which give priority to places on economic security for keeping farmworks, such as cost for using temporary farmers, rather than income loss. In terms of financial system, pay-as-you-go system would be better because of immediate payment with the introduction of the compensation system. The compensation system might be managed and administrated by the existing nationwide organization. Of course, for operating of system review and further research on the technical details such as premium issues and funding problems of government support, the exact classification of the target coverage, premiums based on estimated income for the farmers' estimation, the exact statistical data on the accumulation of agricultural disaster is needed.

Pharmacotherapy is considered the first line therapy in attention-deficit hyperactivity disorder (ADHD). Many patients also choose complementary medicine such as dietary supplements. Omega-3 has shown some efficacy for improving ADHD symptoms in several studies. The goal of this review is to integrate the previous research findings on omega-3 and understand the issues worth considering in the treatment of ADHD. The terms "attention deficit disorder with hyperactivity", "omega-3", and "dietary supplements" were searched on PubMed, Cochrane, and Google scholar. The search was further limited to clinical trials, reviews, and meta-analyses. Trials that examined treatments for ADHD, used randomized design, and placebo-controlled trials were included. Eighteen clinical trials with a total of 1,141 participants were included in this review. Fifteen trials had parallel designs, comparing an omega-3/6 polyunsaturated fatty acid (PUFAs) or a combination of both to a placebo and three compared omega-3/6 PUFAs to a placebo and psycho-stimulants. Seven of the included trials showed significant improvements in groups receiving omega-3/6 PUFAs compared to placebo groups, however, 11 trials showed no significant differences. Evidence that PUFAs supplementation provides benefits for ADHD was yet limited. Mixed results were due to selection variability criteria, variability of supplementation, and short follow-up intervals.

This study selected Nakdong River basin zone in Daegu as an example area to conduct landscapetope classification and aesthetic value assessment of landscape according to the classified landscapetope. The main result of this research can be summed up as following. First, the result of landscapetope type classification showed 28 types of landscapetope including complex residential area (AA), natural stream type with copious vegetation (BA), forest type centered on mixed forest of soft and hardwood (EB) along with 129 types of imputed specific landscapetope. The result of the total first assessment using B-VAT showed the first grade 10 types, II grade 4 types, III grade6 types, IV grade 3 types, 5 types for V grade with the lowest value. The second assessment conducted toward the landscapetope types with the grade higher than the average (including III grade) in the result of the first assessment showed that there are 66 spaces for the sites (1a, 1b) with special meaning for aesthetic landscape evaluation. And also, there were 69 spaces for those (2a, 2b, 2c) with meaning for aesthetic landscape evaluation. The design model of this research is largely divided into improvement goal and specific execution plan. First, the improvement goal is divided into 6 categories including conservation area, complementary area, and restoration area, and the specific execution plan is divided into 14 categories including special landscape management area, general landscape management area, conservation of hill areas with optically good condition. A comprehensive master plan was suggested by directly applying the set landscape planning model to the subject place of this research.
