In clinical clerkships, residents function as trainees, workers, and teachers for other medical students. Although residents care for patients in harsh environments and encounter precarious patient-safety situations, they are working towards becoming competent specialists. Residency education programs are very important in cultivating specialists able to adapt to the rapidly-changing medical environment, and are also necessary to improve the quality of specialist training. Competent specialists not only need clinical competency, but also a wide range of abilities including professionalism, leadership, effective communication, cooperation, and attention to continuous professional development/continuing medical education activities. Each Korean association of specialties has its own educational goals and standardized education programs to help residents learn specific techniques and competencies related to medical care for patients, though the training environment of each residency is different within each trainee hospital. Although it is also important to evaluate residency education programs, currently there is only an examination of knowledge and assessment of skills based on mini-clinical evaluation exercises or direct observation of procedural skills. In order to develop an objective and estimable evaluation tool that can assess the overall achievement level within each training course, it is necessary to evaluate the knowledge, skills, and attitudes of residents. Residency education programs need further attention and reform.

Diagnosis of a Gastrointestinal Stromal Tumor Presenting as a Prostatic Mass: A Case Report

허정식,박경기,김영주,김성대 대한남성과학회 2014 The World Journal of Men's Health Vol.32 No.3

Gastrointestinal stromal tumors (GISTs) are an unusual and heterogeneous group of spindle cell tumors that can also appear on the exterior of the gastrointestinal tract (extra-GISTs). Despite the fact that extra-GISTs or large rectal GISTs can lead to the clinical impression of a prostatic mass, these tumors are, in general, excluded in the differential diagnosis of spindle cell tumors observed on prostate needle biopsy. Here, we present, in detail, a case of an extra-GIST identified on prostatic biopsy; the tumor was previously believed to be a primary prostatic stromal sarcoma in the differential diagnosis. Every investigator should check for KIT (CD117) in immunohistochemical staining to rule out an extra-GIST prior to diagnosing a solitary prostatic tumor, specialized prostatic stromal tumor, or leiomyosarcoma on prostate needle biopsy.

Spontaneous renal rupture is a rare condition. Renal rupture most often occurs as a result of traumatic injury, a rare entity of obstructive uropathy with stones, and spontaneous causes such as malignancy. We report on a rare case of renal rupture caused by a ureter stone measuring 5 mm in size with acute pyelonephritis (APN) in a patient with renal papillary necrosis (RPN). The patient, who suffers from attacks of gouty arthritis, frequently used analgesic for pain relief. The patient was treated with temporary percutaneous drainage and antibiotics. This case demonstrates that RPN with APN can induce renal rupture even when ureter stones are small. Thus, consideration of all medical problems is important when deciding on treatment of patients with ureter stones.

Purpose: Testicular pain or swelling, often referred to as the acute scrotum, can have a number of causes. Common cause of acute scrotal pain include testicular torsion, epidiymitis, testicular appendiceal torsion, and trauma. Color Doppler ultrasonography is being used increasingly in the evaluation of acute scrotum. Diagnostic accuracy is required to avoid the loss of testicular function in the case of testicular torsion and avoid unnecessary surgery in the other causes, we find the ultrasonographic finding of testicular appendiceal torsion. Materials and Methods: We retrospectively reviewed the hospital charts of 26 cases with acute scrotum who had been admitted to our hospital between January 1997 and November 2001 with the except of scrotal trauma. In the event of acute scrotum being suspected, an imaging study was performed. The 11 cases were evaluated with respect to accuracy of diagnosis and outcome of treatment. Results: The incidence of testicular appendiceal torsion was 46% of total acute scrotum boys. Torsion of either appendage produces pain similar to that experienced with testicular torsion. Color Dopper ultrasonography demonstrates increased bood flow of epididymis and secondary hydrocele. Conclusion: The cause of an acute scrotum can usually be established based on a careful history, a thorough physical examination and appropriate diagnostic test. When the history and clinical findings are equivocal. Color Doppler Ultrasonographic finding is usually able to differentiate testicular torsion, which is surgical emergency, from testicular appendiceal torsion which can be treated with conservative management.

기업경영에 있어 정보기술사용에 따른 윤리의식

허정식 한국정보시스템학회 1996 情報시스템硏究 Vol.5 No.-

Ethics refers to the principles of right and wrong that can be used by individuals acting as free moral agents to make choices to guide their behavior. Information technology has presented our human mankind not only prosperity but also harms. This is why moral aspects should be addressed in the application of information system. First, a transforming tendency of international economy will be observed. Second, many issues regarding ethics and behavioral courses will be discussed. And a trend of information technology and five moral models will be examined. Third, traditional morals of Koreans and attitudes of Westerners about information technology will be analyzed. Fourth, it will be also discussed how private firms understand ethics and culture in the context of information handling. It is suggested that individuals who use information technology cultivate efficient and effective ethical principles contributing to public good in the society. For this purpose, the government should establish relevant legal devices.

볼링 동작의 숙련도와 운동속도에 따른 상대타이밍 불변성

허정식 한국스포츠학회 2018 한국스포츠학회지 Vol.16 No.1

이 연구의 목적은 동작 숙련도와 운동속도가 상대타이밍 불변성에 미치는 영향을 규명하는 것이었다. 피험자는 볼링 평균 점수 200점 이상인 숙련자 3명과 평균 점수 110점 정도인 비숙련자 3명이었다. 이들은 모두 오른손잡이며 평균 연령은 23세이었다. 실험과제는 볼링 투구 동작이었으며, 실험 도구는 비디오 카메라, 동작 분석기, 기준척을 사용 하였다. 실험은 숙련도와 운동속도의 2요인 혼합 설계를 이용하여 피험자별 총 10회의 시행을 실시하였다. 종속변인은 상대타이밍 측정치로서 동작의 하위국면 시간비, 가속도 하위국면 시간비 및 위상각이었다. 자료분석을 위해 SAS를 이 용한 분산분석을 실행하였다. 실험분석을 통하여 얻어진 결론은 다음과 같았다. (1) 동작의 숙련도에 따른 상대타이밍 은 불변적이다. (2) 운동속도에 따른 상대타이밍은 불변적이다. (3) 동작의 숙련도와 운동속도의 상호작용에 따른 상대 타이밍은 유의한 차이가 없다. (4) 상대타이밍 불변성은 동작 하위국면의 시간비, 가속도 하위국면 시간비와 위상각을 사용하여 검증할수 있다. 실험을 통하여 동작의 숙련도와 운동속도에 따라 상대타이밍은 불변적이라는 사실을 규명할 수 있었으며, 운동제어 영역에서 논리적 대안으로써 간주되어 온 운동 프로그램 이론과 동력계 이론이 상보적이라는 것 을 입증하였다. 상대타이밍에 대한 차후의 연구는 실험 과제의 측면과 피험자의 기능수준의 측면을 고려해야 하며, 운동 프로그램 이론과 동력계 이론을 더욱 심도 있게 적용할 필요가 있다. The purpose of this study was to investigate the effects of movement skillfullness and movement velocity on relative timing invariance. A experiment was designed to find out the relative timing invariance in bowling throwing motion as a function of movement skillfullness and movement velocity. Subjects were 6 right-handed male undergraduate volunteers. 3 subjects were high-bowlers of average 200 score and others were low-bowlers of average 110 score. Ages from 22 to 25yr. Bowling throw motion was used for complex task. Instrument were video camera, motion analyzer, reference. Experiment was performed in a 2 factors mixed-designed. Trials were 10 times per subject. Conclusions were as follows. (1) relative timing is invariant as a function of movement skillfullness (2) relative timing is invariant as a function of movement velocity (3). relative timing invariance is able to test as using time-ratio of movement sub-phase, time-ratio of acceleration sub-phase and phase angle. From these conclusion, motor program theory and dynamical system theory are considered to be complimentary concepts that focus on different aspects of the human motor behavior.
