Purpose: The purpose of this study was to describe treatment patterns of radiotherapy (RT) for prostate cancer in Korea. Materials and Methods: A questionnaire about radiation treatment technique and principles in 2013 was sent to 83 radiation oncologists and data from 57 hospitals were collected analyzed to find patterns of RT for prostate cancer patients in Korea. Results: The number of patients with prostate cancer treated with definitive RT ranged from 1 to 72 per hospital in 2013. RT doses and target volumes increased according to risk groups but the range of radiation doses was wide (60 to 81.4 Gy) and the fraction size was diverse (1.8 to 5 Gy). Intensity-modulated radiation therapy was used for definitive treatment in 93.8% of hospitals. Hormonal therapy was integrated with radiation for intermediate (63.2%) and high risk patients (77.2%). Adjuvant RT after radical prostatectomy was performed in 46 hospitals (80.7%). Indications of adjuvant RT included positive resection margin, seminal vesicle invasion, and capsular invasion. The total dose for adjuvant RT ranged from 50 to 72 Gy in 24-39 fractions. Salvage RT was delivered with findings of consecutive elevations in prostate-specific antigen (PSA), PSA level over 0.2 ng/mL, or clinical recurrence. The total radiation doses ranged from 50 to 80 Gy with a range of 1.8 to 2.5 Gy per fraction for salvage RT. Conclusion: This nationwide patterns of care study suggests that variable radiation techniques and a diverse range of dose fractionation schemes are applied for prostate cancer treatment in Korea. Standard guidelines for RT in prostate cancer need to be developed.

본 연구는 성장기 II급 부정교합자를 골격 형태에 따라 분류하여 액티베이터 사용 효과를 비교, 분석하고 그 결과를 진단, 치료 계획 수립 등 임상 과정에 연계시키기 위해 시행되었다. 실험은 수완부 방사선 사진상 Fishman 분류의 2, 3, 4 단계로 최대성장기 이전의 II급 부정교합자를 대상으로 하였다. 대조군은 ANB 3도 이상이며 악정형 장치 치료를 받지 않고 치열교정 치료만 받은 환자로 총 25명(남자 15명, 여자 10명)이고 실험군은 액티베이터 치료를 받은 환자로 총 116명(남자 53명, 여자 63명)이었다. Articular angle과 gonial angle을 이용하여 골격 형태를 hyperdivergent type과 hypodivergent type으로 분류하여 액티베이터 치료효과를 비교한 결과 hypodivergent한 골격 형태를 가진 환자에서 더 큰 효과를 보였다. 따라서 성장기 II급 부정교합자의 진단과 치료계획 수립 시 안모의 골격 형태 분류를 통해 액티베이터의 효과를 예측할 수 있다고 생각한다.

Allocation patterns of energy and mineral elements were investigated with phaseolus multiflorus grown in the environmental gradients. The result showed different energy allocation patterns according to relative light intensities and nutrients. The optimal switching time of energy allocation from vegetative to resproductive growth was delated as decreasing relative light intensity. The switch of the shift to reproduction was timed earlier in phosphorus treatment and delayed in nitrogen treatment. Analyzing the mineral elements to various organs, patterns of energy allocation were different from those of mineral allocation. There was no significant difference for allocation patterns in relative light intensity gradients. it was shown that n and p were distributed over the reproductive organs, k mainly in stems, ca in leaves and na in roots. mg was evenly distributed in each organs.

Objectives: This study aimed to understand the current status of clinical practice patterns of Korean medicine in the treatment of degenerative arthritis of the hip and finger joints using web-based survey. Methods: An e-mail questionnaire survey was conducted with the Korean Medicine Doctor(K.M.D) registered in the Korean Medicine Association. The survey data were analyzed using Microsoft Excel. Results: Although the response rate of the survey was low, the characteristics of the respondents generally reflected the characteristics of the study population. A total of 35.2% of the respondents had heard of the guidelines; however, they did not use them for medical treatment. The reason as answered by 32.8% of the respondents was "not enough treatment time to check the manual and apply it." More than half (78.80%) answered that they were treating patients with both degenerative hip and finger arthritis; however, the average monthly number of first-time patients was ≤5. A total of 379 (60.9%) respondents answered that "acupuncture is very important," which was the only one that exceeded the majority compared to other treatments. As a result of the safety investigation, "Acupuncture, herbal medicine, cupping" were considered high in safety, while "Pharmacopuncture and Bee venom acupuncture" were considered low in safety. Conclusions: This survey helped to determine the current clinical practice patterns of Korean medicine treatments, further providing basic data for CPGs for degenerative arthritis of the hip and finger joints.

Functional urinary incontinence, the absence of any neurologic or structural abnormality as a cause of urinary incontinence in children, is one of the most common clinical problems encountered in pediatric and urologic departments, and it can be socially and emotionally distressing for the affected children. The prevalence rates of functional urinary incontinence in school-aged children are not very high and differ between boys and girls. The underlying mechanisms of functional urinary incontinence are heterogenous and can be associated with the following dysfunctions of both the storage and voiding patterns of the bladder: overactive bladder, dysfunctional voiding, lazy bladder syndrome, HinmanAllen syndrome, giggle incontinence, and vaginal voiding. Treatment methods for urinary incontinence in children should be chosen according to these clinical conditions. Treatment modalities generally consist of the treatment of comorbid conditions such as urinary infection and constipation, behavior therapy to modify learned voiding patterns, and pharmacotherapy primarily with anticholinergics and ${\alpha}$-adrenergic blockers. This review discusses the optimal treatment modalities, including treatment of the underlying voiding disorders, and diagnostic approaches related to functional urinary incontinence in children.

To study the effects of metal ions on the activity of anti-oxidase enzymes, the activity of superoxide dismutase (SOD) and peroxidase (POD) and isozyme patterns of Brassica juncea have been studied after treating with CD, Cu, Zn, and Al. The activity of SOD after treating with metal ions was higher than that of untreated control. SOD activity in leaves increased by treatment of 50 ppm of Zn and 500 ppm of Al. POD in stems gave highest activity after treating with 500 ppm of Cu. When the activity was compared by plant parts, lowest POD activity was observed in leaves in which protein content was higher than other tissues. When the activity was expressed as percentage of control, SOD activity was increased after treating with metal ions. SOD activity in leaves and roots of metal treated plant was significantly increased under the metal ions stress conditions. In the roots of 50 ppm of Zn treated plant, SOD activity was extremly high. POD activity was inhibited with Cd and Zn treatment in all parts of the plant. However, in leaves and stems, there was marked increase in activity after treating with Cu. The patterns of SOD isozyme after metal treatment show that two bands were stained in all metal ion treated and that no new band appeared. POD isozyme band intensity resulting from the treatment of metal ions was in order of roots > stems > leaves, but there was no significant difference.

Purpose: Oromandibular dystonia is a neurological disorder that affects the jaw and lower face muscles, often resulting in abnormal repetitive movement of the jaw and perioral structures. The purpose of this study was to assess the effectiveness of surface electromyography (EMG) in evaluating the treatment outcome of oromandibular dystonia. Methods: Based on a retrospective review of medical records, we analyzed the data of four patients who received medication or botulinum toxin injection, as well as surface EMG of the jaw muscles before and after treatment. We assessed the patients' clinical characteristics and the results of surface EMG before and after treatment. Results: The case series included one female and three males, and the age range was 65-78 years. Based on the clinical features, two subjects were classified as jaw deviation and the remaining two were as jaw closing. Dystonic patterns revealed by surface EMG varied, including phasic, tonic, and mixed contraction patterns. EMG amplitude after treatment was lower than pre-treatment value in all four subjects, suggesting improved clinical signs and symptoms. One subject who received clonazepam and another who received botulinum toxin injection showed a remarkable reduction in EMG amplitude within a normal range. Conclusions: Surface EMG can be used to effective evaluate treatment outcomes in patients with oromandibular dystonia. It could be considered as an adjunctive diagnostic tool in managing patients with dystonia.

Nanofabrication is an essential process throughout industry. Technologies that produce general nanofabrication, such as e-beam lithography, dip-pen lithography, DUV lithography, immersion lithography, and laser interference lithography, have drawbacks including complicated processes, low throughput, and high costs, whereas nano-transfer printing (nTP) is inexpensive, simple, and can produce patterns on non-plane substrates and multilayer structures. In general nTP, the coherency of gold-deposited stamps is strengthened by using SAM treatment on substrates, so the gold patterns are transferred from stamps to substrates. However, it is hard to apply to transfer other metallic materials, and the existing nTP process requires a complicated surface treatment. Therefore, it is necessary to simplify the nTP technology to obtain an easy and simple method for fabricating metal patterns. In this paper, asnTP process with poly vinyl alcohol (PVA) mold was proposed without any chemical treatment. At first, a PVA mold was duplicated from the master mold. Then, a Mo layer, with a thickness of 20 nm, was deposited on the PVA mold. The Mo deposited PVA mold was put on the Si wafer substrate, and nTP process progressed. After the nTP process, the PVA mold was removed using DI water, and transferred Mo nano patterns were characterized by a Scanning electron micrograph (SEM) and Energy Dispersive spectroscopy (EDS).
