Actinic lichen planus is a particular subtype of lichen planus with a distinct photodistribution. This disease has been variously named lichen planus in subtropical countries, such as lichen planus subtropicus annularis, lichen planus tropicus, summertime actinic lichenoid eruption, and lichenoid melanodermatitis. It is a disorder seen most frequently in Africa, the Middle East, and the Indian subcontinent, favoring Asiana. This disease presents in the spring or summer and is frequently quiescent during the winter. A 61-year-old man with unusual lichenoid photosensitive eruption is presented. The lesions developed during the late spring, appearing on both dorsa of hands, wrists, and lower legs. We report a case of actinic lichen planus with a review of the literature.

We report a case of type IIa hyperlipoproteinemia with xanthoma tendinosum associated with coronary artery disease in a 51 year-old male. Multiple hard nodules appeared firstly on both achilles tendon area 30 years ago and the lesions gradually spread to the dorsa of hands and feet. On past history, he had been diagnosed as unstable angina with atherosclerosis of three vessels in coronary arteries, 2 years ago. His family history revealed nothing contributory. Serum lipid profile including lipoprotein electrophoresis showed an increase in total cholesterol and LDL-cholesterol with increased P-lipoprotein fraction, which suggested type IIa hyperlipoproteinemia. Histopathologic finding of a nodule from the dorsum of right hand showed many foamy histiocytes and cholesterol clefts in the dermis. Most of the xanthoma cells were mononuclear, but many Touton type giant cells were seen also. He died suddenly of heart failure with unstable angina. (Korean J Dermatol 2003;41(11) : 1541-1543)

지금까지 퓨리에 변환이 신호 처리법으로 가장 널리 사용되고 있다. 그러나, 이 방법은 신호의 주파수 성분이 시간에 대하여 어떻게 변화하는지를 표현하지 못한다. 따라서, 최근 이와같이 비정상신호를 표현하지 못하는 퓨리에 변환의 단점을 보완하여, 신호의 시간과 주파수에 대한 정보를 동시에 표현할 수 있는 시간-주파수 해석법들이 개발되기 시작하였다. 본 연구에서는 인공열화된 SUS 316강의 초음파 신호를 시간-주파수 해석법으로 분석하였다. 특히, 단시간 퓨리에 변화법과 위그너 빌 분포법을 이용하여 초음파 신호의 주파수 성분과 특성을 분석하였다. Fourier transform has been one of the most commonly used tools in study of frequency characteristics of signal. However, based on the Fourier transform, it is hard to tell whether a signal's frequency contents evolve in time or not. Recently, to overcome Fourier transform fault, not to represent non-stationary signal, time-frequency analysis methods are developed and those can represent informations of signal's time and frequency at the same time. In this study, we analysed ultrasonic signal for degraded SUS 316 with time-frequency analysis method. In particular, the methods such as short time Fourier(STFT) and Wigner-Ville distribution(WVD) were used to extract frequency contents and characteristics from ultrasonic signals.

Background : As parking problem caused by increasing owner-driver and patients concentration to a general hospital is becoming one of the dissatisfactions in medical care. It is time that a general hospital should solve the parking problem in a desirable way. The purpose of this survey is to let the clients understand the basic motivation of the pay parking and develop the better parking system. Methods : Clients of a tertiary care hospital in Chon-ju were surveyed by means of a questionnaire. All in all, 193, subjects answered the questionnaire. Results : In relation to the previous experiences, 39.6% of the subjects experienced inconvenience with confuse parking lot and the shortage of parking space. Under the were more than those who didn't 62.7% of the subjects answered that the y could find the parking lot easily. 33.2% of the subjects mentioned that it was not easy to drive in the parking area ; The reasons were pointed out the shortage of space, disordered parking, and insufficient guide, 12.8% of the subjects satisfied with the current administering system of parking lot. The outpatients were more affirmative than the admitted patients about the charging system. As for the parking fee, 64% of the subjects answered that it is expensive, and 89.5% of the subjects answered that it is expensive, and 89.5% of the subjects thought imposing of parking fee is irrational. Conclusion : To say as a whole, th basic purpose of the charging system are more of less accepted. However, the management details like parking facilities and payment method are dissatisfactory, so it is necessary to improve the management system. It is also noted that the inpatients showed more negative attitude than the outpatients with the charging system. To secure a more convenient parking, the parking system should be considered in relation to the information service, kind guidance, improve facilities, personnel cooperation, fix outpatient scheduling system. etc.

Objectives The Mental Health Act is an initiative aimed at changing and shaping mental health services and protecting human rights of persons with mental disorders. Since the Mental Health Act was legislated in 1995, four amendments have been made according to the issues that arose from public concerns. However, there are still many debates about the human rights protection of the mentally iII. This study aimed to provide information regarding major aspects of the Mental Health Act by comparing them among several developed countries. Methods Current Mental Health Acts of the state of Michigan in the United States, Scotland in England, the state of Victoria in Australia, and Japan were reviewed. Issues regarding the Korean Mental Health Act were collected from seminar materials, news media contents, and mental health professionals Results The definition of subjects in Korean Mental Health Act was more inclusive than other countries and was derived from a medical classification of mental illness. Family members or guardians were granted important responsibilities for deciding the involuntary admission of mentally ill patients in Korea and Japan. In Western countries, Mental Health Review Tribunals or courts have the primary responsibility for important decisions about mentally ill patients. The regulation of immediate dis- charge after request by voluntarily admitted patients was not enacted in all countries except Korea. The mandatory procedure for involuntary admission in Western countries includes an individual case review with personal interview by a Mental Health Review Tribunal or court. Conclusion The Korean Mental Health Act appears to meet the basic standards of Guidelines from international organizations. Our traditional culture and inherent health systems seem to influence the legal regulation of mental health service and might be related to the problems of human rights protection of mentally ill patients in Korea.

Laparoscopic sleeve gastrectomy can reduce morbidity and mortality in patients with morbid obesity, but it can cause complications such as a gastrointestinal leak. A 30-year-old morbidly obese female who had type 2 diabetes mellitus and hypertension with estimated body mass index of 40.2 kg/m2 was admitted. Laparoscopic sleeve gastrectomy was performed. On postoperative day 19, a leak was suspicious on physical examination and radiologic findings. Conservative management was performed, but the patient was hemodynamically unstable and imminently septic. After laparoscopic drainage procedure, esophagogastroduodenoscopy was performed and revealed the fistula opening at staple line just below gastroesophageal junction. Fibrin tissue adhesive was injected around the fistula and the esophageal covered stent was inserted to cover the leak. At 14th days after stent insertion, the barium study confirmed no more leak. In this case, we experienced that the esophageal stent insertion with fibrin tissue adhesive injection may reduce recovery time of the fistula developed after laparoscopic sleeve gastrectomy

Ki-Chan Park,Joo-Hyun Choi,Tae-Soo Suk 피터드러커 소사이어티 2013 창조와 혁신 Vol.6 No.2

The Korean Wave (or Hallyu in Korean) refers to fast growth in the popularity of South Korean culture. is spreading in many parts of the world and especially in the Asian countries in a form of Korean-Pop (or K-Pop) and Korean-Drama (or K-Drama). This paper examines the sustainability of the Korean Wave by analyzing the industries other than entertainment such as education. culture and advanced technologies. The main focus of this case study is Korean education system in terms of its historical and social phenomena which we call "the zeal for education" in Korea. We conducted an extensive search in the journals and research papers published since January 2011 that allowed us to apply SWOT analysis to formulate S-O strategies for sustainable Korean-Wave in education. The implications for Korean education wave in Southeast Asia that we drew from the analysis of this case are follows: first, provide the education products that are customized and segmented for each ASEAN country. Second, provide the convenient living infrastructures for the inbound ASEAN students to Korea. And provide the harmonized education policies by linking the learning with the job opportunities. The challenging question remained is 'how to cope with the global responsibility of Korean Wave in education with the fever of Korean Wave in Asian countries.

Original Articles : Factors Influencing Corneal Flap Thickness in Laser In Situ Keratomileusis with a Femtosecond Laser

( Chan Young Kim ),( Ji Hye Song ),( Kyoung Sun Na ),( So Hyang Chung ),( Choun Ki Joo ) 대한안과학회 2011 Korean Journal of Ophthalmology Vol.25 No.1

Purpose: To evaluate factors responsible for the variability between intended and achieved corneal-flap thickness during femtosecond laser-assisted laser in situ keratomileusis (LASIK). Methods: A prospective, nonrandomized, case study was performed on 35 eyes of 18 consecutive patients who underwent LASIK surgery using the 60 kHz femtosecond laser microkeratome. Eyes were assigned to three different thickness groups, with 110-, 120-, or 130-μm cut depths. Anterior segment optical coherence tomography was used to assess the morphology of 35 LASIK flaps at postoperative one week postoperatively. The flap thickness was assessed at seven measuring points across each flap. Patient age, preoperative spherical equivalent, manual keratometry, preoperative central pachymetry, and regional variability of the cornea were evaluated to determine where they influenced the achieved corneal flap thickness. Results: Cuttings of all flaps were easily performed without any intraoperative complications. Flap-thickness measurements had a mean of 115.21 ± 4.98 μm (intended thickness, 110 μm), 121.90 ± 5.79 μm (intended, 120 μm), and 134.38 ± 5.04 μm (intended, 130 μm), respectively. There was no significant difference between the 110-μm and 120-μm groups when compared with the 130-μm group (one-way analysis of variance test, p>0.05). Patients` age, preoperative spherical equivalent, manual keratometry, and preoperative central pachymetry did not affect the achieved flap thickness (Pearson correlations test, p>0.05). The reproducibility of flap thickness in the central 1.5-mm radius area was more accurate than that in the peripheral 3.0 to 4.0-mm radius area (paired samples t-test, p<0.05). Conclusions: Femtosecond laser-assisted LASIK is likely to reproduce a reliable thickness of the corneal flap, which is independent of corneal shape factors or refractive status. Future studies should focus on variations in corneal biomechanical factors, which may also play an important role in determining flap thickness.

Conconi-Test(비침습적 AT 추정방법)의 실험적 검증

주기찬,장창현 서원대학교 응용과학연구소 1994 응용과학연구 Vol.3 No.1

The purpose of this study was to verify the availability of Conconi Test. To accomplish this purpose Conconi Test was done in laboratory with 10 subjects, who were physically trained university students. After the test deflection point of HR(Vd) was detected by regression analysis and LT, VT was determined according to former researches. To verify whether the Vd and LT, Vd and VT were coincident the t-test was done between the level of each variables, correlation between Vd and LT was calculated. The results of this study was as follows; 1. The deflection point of HR could be found in conconi test. 2. The exercise intensity of Vd and LT was not concident in the significance level of .05, and the exercise intensity of Vd and VT was not coincident in the significance level of .01 3. The correlation between Vd and LT was not as high(r=0.6014) as in the results of Conconi's research(r=0.99) 4. The LT and VT level of subjects were 70.76%-VO₂max, 68.85%-VO₂max respectively, with above findings, it could be concluded that the availability of Conconi Test was questionable. But VD appered above AT in all subjects and this means Vd could be used as standard for determining anaerobic training intensity. Further research is needed for finding physiological rationale of Vd because Conconi Test is non-invasive comportable method.
