Priapism is a persistent penile erection that continues for more than 4 hours beyond, or is unrelated to, sexual stimulation. Because priapism is a medical emergency, all patients with priapism should be evaluated and treated urgently. Subtypes of priapism are ischemic, non-ischemic and stuttering priapism. Stuttering type is a recurrent form of ischemic priapism in which unwanted painful erections occur repeatedly with intervening periods of detumescence. The etiology of this type is often idiopathic and the treatments are still not clearly established. We present one case of stuttering priapism which occurred after suppression of his sexual desire. A 23-year-old man visited our clinic complaining of recurrent pain and erections persisting for about 5 weeks. We performed evaluation and confirmed the diagnosis of Rigid swollen penis. Jibaekjihwang-tang gamibang (ZhiBaiDihuang-Tang Jiaweifang) was administerd to the patient for 9 days. After the treatment, duration of erections and pain showed remarkable improvements. This will be recorded as the first case report of treating priapism with a Korean medical approach and suggests that Korean medicine therapy can be efficient to treat priapism.

Obejectives : To investigate the clinical effect of electroacupuncture and bee venom acupuncture for benign prostatic hyperplasia(BPH) symptoms. Methods : Among 39 outpatients who were treated at a BPH clinic, 8 were finally selected for analysis by charts-review, retrospectively. They were treated by electroacupuncture and bee venom acupuncture more than 3 times. We estimated the effectiveness of the treatments by using the International Prostate Symptom Score (IPSS) questionnaire and checking their nocturia frequency. On the basis of these variables, we analyzed the statistical significations of symptom improvements. Results : Among 8 patients, the IPSS and nocturia frequency showed significant improvement after the final treatment compared with baseline (P = .0078, P = .0078). The IPSS significantly decreased even after the 1st treatment and also after the 2nd treatment compared with the baseline (P = .0078, P = .0078). The IPSS at post final-treatment, post 1st- and post 2nd treatment also showed significant improvement compared with IPSS at baseline in 6 severe symptomatic patients(P = .031, P = .031, P = .031). Nocturia frequency decreased after the 1st treatment compared with baseline and showed significant improvement between baseline and post 2nd treatment (P = .0078). Conclusions : In a retrospective and cross-sectional study investigating the clinical effects of electroacupuncture and bee venom acupuncture on BPH, these treatments proved to have significant therapeutic effects, particularly for various symptoms involving frequent nocturia.

In this study, the effect of H2O2 addition on ferric coagulation for phosphorus removal. The experiments were conducted under H2O2/Fe molar ratio of 0.4∼6.0; rapid mixing intensity with G value of 500 s-1. The effect of H2O2 injection sequence was investigated also. The characteristics of floc growth were measured by flocculation index (FSI) using the PDA. The removal efficiencies of phosphorus were increased as H2O2/Fe molar ratio increased. However, The removal efficiencies of phosphorus were decreased over the H2O2/Fe ratio 4. Higher removal efficiencies of phosphorus and floc size were observed with sequence dose of ferric coagulant and hydrogen peroxide.

본 연구의 목적은 케틀벨을 이용한 힙드라이브 스윙운동이 다리근력에 어떠한 영향을 미치는지 알아보고 추후 임상에서의 다리근육의 근력 강화에 활용될 수 있는지의 가능성을 제시하고자 한다. 연구를 위하여 20대 성인 30명을 실험군 15명, 대조군 15명으로 무작위 배치하였으며, 8주 동안 주 3회 운동을 실시하였다. 각 집단은 운동 전과 운동 8주 후에 휴대용 근력 측정기를 사용하여 엉덩 폄, 무릎 폄, 무릎 굽힘, 발바닥 굽힘의 근력을 측정하였다. 자료 분석을 위하여 독립표본 t-검정과 대응표본 t-검정을 사용하였다. 그 결과 그룹 간에는 유의한 차이가 없었고, 시기에서 실험군은 엉덩 폄, 무릎 폄, 무릎 굽힘, 발바닥 굽힘의 근력에서 시기에 따라 유의한 차이가 있었고(p <.05), 대조군은 무릎 폄, 발바닥 굽힘에서 유의한 차이가 있었다(p <.05). 따라서 향후 다리근력에 대한 본 연구의 케틀벨을 이용한 힙드라이브 스윙운동이 임상에서 다리근력 강화 중재 방법의 자료로 제공될 수 있을 것으로 사료 되며, 또한 다양한 환자들을 대상으로 연구가 이루어져야 할 것으로 생각된다. The purpose of this study was to investigate the effect of hip drive swing exercise using a kettlebell on lower extremity muscle strength and to examine its possible use for strengthening lower extremity muscles in clinical practice. Thirty adults were randomly and equally assigned to an experimental group or a control group, all thirty were exercised 3 times a week for 8 weeks. Strengths of hip extension, knee extension, knee flexion, and plantar flexion were measured using a portable muscle strength tester before and after the 8-week exercise period. The analysis was conducted using the independent t-test and the paired t-test. Hip extension, knee extension, knee flexion, and plantar flexion strengths increased significantly in the experimental group during the exercise period (p <.05), and knee extension and plantar flexion strengths increased significantly in the control group (p <.05). However, no significant difference was found between the two groups. Our findings suggest that hip drive swing exercise using kettlebells for strengthening lower extremity muscle strength could be used as an interventional method for strengthening lower extremity muscle strength in clinical practice. We recommend that the merits of this lower extremity muscle strengthening method be investigated further in a variety of patients.

국내 문화재와 관련된 여러 재단은 해외 한국문화재 소장 기관의 협조를 얻어 국외소재 한국문화재를 조사하고 있고, 조사 결과는 보존·복원 및 전시, 교육 등의 활용기반이 되고 있다. 국외에서 한국문화재에 대한 연구조사 및 전시 등의 활용은 활성화 되어있는 반면 국내는 연구조사 결과를 통한 활용의 사례가 많지 않으며, 국외소재문화재에 대한 접근성 또한 낮다. 본 연구의 목적은 국외소재 한국문화재에 대해 국내에서의 활용할 수 있는 방안을 모색하는 것이며, 디스플레이 전시와 온라인 박물관은 국외소재 한국문화재를 활용할 수 있는 방안이 될 수 있을 것이다. 이를 통해 국외소재 한국문화재에 대한 접근성을 높이고 전시, 교육 등 다양한 분야로 활용할 수 있을 것이다. Several Korean cultural property-related foundations have investigated Korean cultural property located abroad with the help of international organizations owning Korean cultural objects and the investigation results serve as the basis of preservation/restoration, exhibition, and educational efforts. Korean cultural objects have been widely used abroad, for instance, for research and exhibition purposes, whereas in Korea, there are still only very few examples of using cultural property based on research results and accessibility to cultural property located abroad is also low. The aim of this study is to explore plans to utilize Korean cultural property located abroad in Korea, and exhibition displays and online museums can be good ways to utilize Korean cultural property located abroad. These will help increase access to Korean cultural property located abroad and find a variety of applications, including exhibitions, education.

공정관리는 건설 프로젝트의 효율적인 수행을 위한 핵심 역량 중의 하나이다. 공정관리를 수행하기 위한 지원 도구로서 많은 상용 공정관리 솔루션이 개발되었지만, 건설 현장에서는 사용법을 잘 알지 못하고 있는 등 여러 가지 이유로 인해 활용도가 높지 않은 것이 현실이다. 본 연구에서는 설문조사를 통해 공정관리 및 관련 솔루션 사용에 관한 현황 및 문제점을 파악하고, 이를 기반으로 상용 공정관리 솔루션 활용도를 높이기 위한 공정표 작성 지원 프로그램을 개발하였다. 개발된 프로그램을 통하여 현장에서의 상용 공정관리 솔루션의 활용성을 높이고, 결과적으로 효율적인 공정관리를 기대할 수 있을 것이다. Scheduling management is one of the most important factors for the efficient performance of construction projects. Various computer-aided solutions for schedule management have been developed, but they are not commonly used in practice. This study conducted surveys on scheduling management methods and the related solutions to identity their status and problems in practice. Based on the results of the surveys, this study also developed a scheduling assistant program to improve the usability of scheduling management solutions. Through the developed program, the usability of scheduling management solutions will be improved in practice, thus enabling efficient scheduling management.

The introduction of new therapeutic agents in recent years has led the early diagnosis of rheumatoid arthritis (RA) increasingly important. Therapeutic intervention early in the disease course of RA allows earlier disease control and less joint damage. The 1987 American College of Rheumatology classification criteria for RA, however, does not reach full efficiency for providing clinicians to distinguish RA from other arthritides in the early phase of the disease. Therefore, diagnostic tools are needed to establish a reliable diagnostic criteria although the lack of an independent gold standard for RA makes it challenging in the evaluation of diagnostic studies. RA has no disease specific clinical, radiological or immunological features. This review describes the diagnostic values of medical history, physical examination, laboratory tests and imaging studies as well as the 1987 American College of Rheumatology classification criteria in the diagnosis of RA in its early phase.
