Under the pressure to open the service market as proposed by World Trade Organization, we can easily expect our educational systems for allied health professions will experience a lot of changes in near future. Accordingly, we compared our current educational systems for allied health professions with the foreign ones and mapped out some strategies predicting the forthcoming enormous changes. Major investigations and analysis are summed up as follows, The educational programs for allied health professions which was started in 1963 in Korea are stilled remained as 2 to 3 school years, while the systems in advanced countries have already been changed or been changing from 2 year to 4 year college levels. We can hardly find the uniform educational system or school years for the allied health professions in the world except for Korea. Fortunately, university level four-year programs for the profession was established in 1979 in Won-joo for the first time in Korea. However, there are still only few four-year programs in this country. To meet the rapidly changing needs we have faced in the health areas we should supply appropriate health personnel through various efforts. Now we would like to suggest followings, <Educational goals for the allied health professions> 1) reconfirming characteristics for the educational goals of health professions 2) extending school years for the allied health professions 3) strengthening clinical training and internship 4) expanding opportunities for the continuing education through lifelong education 5) upgrading from old-fashioned technologies to advanced technologies 6) cultivating competencies of health professionals for the global competition <Suggestions for the Development of Allied Health Professions> 1) reforming the school years of educational programs for the allied health professions to meet the global standards 2) expanding the role of junior college programs for the allied health professions through the development of intensive courses in the professions. 3) diversifying and specializing the allied health professions mainly through 4 year B.S. degree programs.

요류 측정술을 이용하여 전립선 비대증 환자 40례에서 경요도 전립선 절제술후 치료 효과를 평가하여 보고한다. Uroflowmetry has been proposed as a non-invasive screening test and may be used to reveal lower urinary tract dysfunctions, such as benign prostatic hyperplasia, urethral stricture and neurogenic bladder. We tested 40 patient of benign prostatic hyperplasia (BPH) diagnosed with clinical manifestations, IVP and cystoscopy. Group 1 including 15 patients performed both preoperative and postoperative uroflowmetry. Group 2 including 25 patients shown acute urinary retention preoperatively, performed only postoperative uroflowmetry. The results were obtained as follows. 1.In group 1, average preoperative maximum flow rate (MFR) was 7.2 cc/sec and postoperative MFR was 20.1 cc/sec (P<0.01). On flow rate normogram, preoperative MFR of all patients was below -2 standard deviations (SD) and average MFR was -3.1 SD. In postoperative MFR, below -2 SD values showed in 3 patient, -1 SD ~-2 SD in 6, -1 SD ~ mean in 4, above mean values in 2 and average MFR was -1.3 SD. 2.In Group 2, postoperative average MFR was 22.3cc/sec, below -2 SD values showed in 6 patients. -2 SD∼ -1 SD in 5, -1 SD - mean in 8, above mean values in 6 and average MFR was -0.93 SD. 3.MFR values of group 1 increased an average of 2.8 SD in each patient and 80% of patients were improved in uroflowmetry after transurethral resection of prostate (TURP). 4.If MFR of acute urinary retention was below -2 SD in group 2, 76% of patients were improved in uroflowmetry after TURP.

Vapours from origanum oil (O) and thyme oil (T) were applied to the four soil-borne strawberry pathogens Fusarium oxysporum f. sp. fragariae, Colletotrichum fructicola, Lasiodiplodia theobromae, and Phytophthora cactorum, causing Fusarium wilt, anthracnose, dieback, and Phytophthora rot, respectively. Increasing T vapour doses in the presence of O vapour strongly inhibited mycelial growths of the four pathogens and vice versa. When mycelia of F. oxysporum f. sp. fragariae and P. cactorum exposed to the combined O + T vapours were transferred to the fresh media, mycelial growth was restored, indicating fungistasis by vapours. However, the mycelial growth of C. fructicola and L. theobromae exposed to the combined O + T vapours have been slightly retarded in the fresh media. Prolonged exposure of strawberry pathogens to O + T vapours in soil environments may be suggested as an alternative method for eco-friendly disease management.
Relationship between intraocular pressure and systemic health parameters in the Korean population

This study examined the influence of age, sex, blood pressure, and obesity index on intraocular pressure (IOP), in order to investigate the relationship between the upper limits of the following two conditions in the general Korean population: the “systolic or diastolic hypertensive and obese” group and the “systolic or diastolic hypotensive and lean” group. A total of 6828 healthy subjects (13,656 eyes) underwent automated multi-phasic tests, including tonometry, blood pressure, visual field, and body mass index. The 6,828 subjects were divided into five groups based on age; less than 40, 40 to 49, 50 to 59, 60 to 69, and over 70 years old. They were also divided into four categories on the basis of sex, age, blood pressure, and obesity index. The mean IOP in males (15.8±3.3 mmHg) was significantly higher than in females (14.8±3.1 mmHg) (P < 0.05), but this difference decreased proportionally with increasing age. IOP had a tendency to decrease with increasing age (P < 0.05). IOP increased significantly with increasing systolic blood pressure, diastolic blood pressure and obesity index (all, P < 0.05). The mean IOP of the “systolic or diastolic hypertensive and obese” group was higher than that of the “systolic or diastolic hypotensive and lean” group in the general Korean population (P < 0.05). These data could aid investigation into the epidemiological, etiologic and oriental influences related to the risk factors of glaucoma, especially in oriental populations.

최근에 시계열에서의 이상치 발견을 위한 여러가지 반복적인 방법들이 소개되었으나 이들 대부분은 시계열의 기저모형이 알려져 있거나 식별될 수 있다는 가정하에서 개발되었다.그렇지만 실제로 이상치들이 모형식별을 왜곡 시키거나 심지어는 불가능하게 만드는 경우가 발생한다. 본 논문에서는 두 개의 시계열 관측치 사이의 거리에 근거한 새로운 척도를 이용한 이상치 탐색 방법을 제시하였다. 특히 이방법은 이상치를 발견하는데 시계열 모형에 의존하지 않는다. 제안된 통계량에 대한 여러가지 성질을 밝혔으며 이상치의 형태를 구별하기 위해 전이함수모형을 이용하였다. 그 밖에 이상치를 포함하고 있는 시계열의 모형을 구축하기 위한 반복적인 절차를 제안했다. Recently several authors have introduced iterative methods for detecting time series outliers. Most of these methods are developed under the assumption that an underlying outlier-free model is known or can be identified. Since outliers can distort model identification or even make it impossible, we propose in this article a model independent procedure for detecting outliers. The proposed procedure begins with a descriptive data analysis of a time series using distance measures between two observations. Properties of the proposed test statistic are presented. To distinguish the type of an outlier are used transfer function models. An empirical example is given to illustrate the time series modeling procedure.
Nonlinear Absortption processes in Triphenyamine-dithienothiophene-Triphyenylamine

We investigated the nonlinear absorption mechanism in the triphenylamine-dithienothiophenetriphenylamine molecule by using laser pulses with two different pulse widths, 7 ns and 35 ps. The single-beam transmission measurement with a 7-ns pulse resulted in a larger nonlinear absorption than that with a 35-ps pulse and saturated at high input intensities due to the excited state absorption (ESA) initiated by two-photon absorption (TPA). For a quantitative characterization of the TPA and ESA contributions to the nonlinear absorption, we estimated the ESA spectrum and lifetime by using a pump-probe transmission measurement with a 35-ps pulse. A 5-level model was used to explain both the nonlinear absorption and the one-photon and the two-photon pumped fluorescence.
