  • Objectives: This study was conducted to observe the progression of symptoms according to the treatment period of patients with social anxiety disorder who received complex Korean medicine treatment. Methods: The medical records of 25 patients who were diagnosed with social anxiety disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and received complex Korean medicine treatment (herbal medicine, acupuncture, and Korean psychotherapy) for 12 weeks were analyzed. The State-Trait Anxiety Inventory (STAI), the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), the Korean-Social Avoidance and Distress scale (K-SAD), and the Korean-Fear of Negative Evaluation (K-FNE) were measured at the initial hospital visit and during the 4, 8, and 12 weeks of treatment to evaluate the effectiveness of treatment. Missing values were replaced with the average evaluation index value at that time. Results: 1) Statistically significant changes in STAI-X1, STAI-X2, BDI-II, BAI, K-SAD, and K-FNE scores were seen according to the time of treatment. 2) When scores were compared between each treatment time point, STAI-X2 and BDI-II showed statistically significant changes between the initial visit and four weeks of treatment, the initial visit and eight weeks of treatment, and the initial visit and 12 weeks of treatment. STAI-X1 and K-FNE showed statistically significant changes between the initial visit and eight weeks of treatment and the initial visit and 12 weeks of treatment. There was a statistically significant change in BAI scores between the initial visit and the 12th week of treatment. Conclusions: Complex Korean medicine treatment alleviated anxiety, depression, fear, and avoidance of social situation symptoms in patients with social anxiety disorder. The longer the treatment period, the more symptoms tended to be alleviated. However, the evidence should be supplemented with prospective, controlled research.

  • 대형병원의 의료 서비스 수준이 점차 높아지면서 이를 이용하려는 환자들이 늘어남에 따라 환자들이 받아야 할 진료의 대기 시간이 증가하여 병원 이용에 어려움을 겪고 있다. 따라서 진료 대기 시간을 단축하기 위하여 처방 전달 시스템, 진료 안내 시스템 등의 다양한 연구들이 진행 중이다. 그러나 기존에 제안되었던 연구들은 환자가 받아야 할 진료들의 상황을 고려하지 않고 순차적으로 진료 순서를 정하기 때문에 환자의 병원 이용 시간이 증가한다는 단점이 있다. 본 논문에서는 환자가 받아야 할 진료들의 예상 대기 시간과 평균 진료 시간을 더한 값인 예상 체재 시간이 가장 작은 진료를 추천하는 상황인지를 이용한 진료 안내 시스템을 제안한다. 상황인지를 이용한 진료 안내 시스템은 추천된 진료 순서를 바탕으로 환자의 스마트폰에 진료 정보 안내 서비스를 제공한다. 본 논문에서 제안한 상황인지를 이용한 진료 안내 시스템을 이용하면 환자가 병원에 머무는 시간이 최소화되며, 같은 시간 내에 최대한 많은 환자를 진찰할 수 있는 장점이 있다. 제안한 상황인지를 이용한 진료 안내 시스템과 기존 처방 전달 시스템의 성능 비교를 통하여 진료 순서 추천 방법의 우수함을 보인다.

  • Alkaline treatment gives Sea-Island type yam to produce microfiber and silk-like touch. But this treatment have some problems in dyeing and finishing process. To solve some problem occurred in dyeing and finishing of polyester fabric, the ultrasonic treatment technique was used recently. This study was carried out to confirm the effect of the ultrasonic treatment on alkaline weight loss finishing of polyester fiber under general alkaline treatment conditions; NaOH concentration 2, 3, 4, and 5%, treatment time 5, 10, 15, and 20 minutes, treatment temperature 70, 80, 90, and 99'E, respectively. On the other hand, the three way lay out method was used to test of significant obtained data from alkaline treatment. It was found that weight loss increased with increasing the NaOH concentration, temperature, and time. Also, in case of PET/Co-PET fabrics by ultrasonic, weight loss and dissolution of microfiber were superior to PET/Co-PET fabrics without ultrasonic. Tensile strength and modulus decreased with increasing NaOH concentrations and hydrolysis time. Therefore, the effect of alkali hydrolysis by ultrasonic application was better than that of the conventional method.

  • 본 논문은 multiplex deposition sputter system을 사용하였고 ITO 유리기판 위에 CdS 박막을 증착하여 투과율을 향상시키고 제작비용을 절감하는데 목적을 두었다. CdS 박막을 제작할 때 열처리시간을 변화시켜 태양전지를 제작할 때 우수한 조건을 찾고자 하였다. 열처리 시간 변화에 따른 두께와 면 저항은 큰 차이가 없는 것으로 관찰되었다. 비저항은 최소값 6.68에서 최대값 6.98로 측정되었다. 열처리 시간이 20분 이상하였을 때 투과율은 75% 이상으로 측정되었다. 열처리시간이 10분일 때 밴드갭은 3.665 eV이고 20분 이상은 3.713 eV로 똑같은 결과로 측정되었다. XRD를 분석한 결과 CdS의 구조는 hexagonal로 나왔으며 다른 불순물이 없이 CdS 박막 만 증착되었다. 반치폭 (FWHM)을 계산한 결과는 열처리시간을 20분으로 하였을 때 0.142로 최대값으로 측정되었고 40분일 때 0.133으로 최소값으로 측정되어 열처리 시간을 변화 주었을 때 반치폭은 큰 차이가 없었다. 입자 크기를 측정한 것으로는 열처리시간을 40분으로 하였을 때 11.65 Å으로 최대값이고 20분일 때 10.93 Å으로 최소값으로 측정되었다.

  • In this paper, the long time breakdown characteristic of the epoxy composite, which is widely used in the insulation system for high voltage application, was estimated with Weibull distribution. In the procedure of the estimation, the short time breakdown characteristics for the epoxy composite specimens, which were made with the variation of hardener and/or filler, were tested firstly. Then the long time voltage-to-time test was implemented. Finally, the long time breakdown voltage of each specimen was estimated with the parameters obtained from the statistical treatment with Weibull distribution. Base on the results, it has been found that the optimal weight ratio of epoxy resin/hardener/filler that has the excellent long time breakdown characteristic was 100/100/65. It was due to the silane treatment which relieves the electric field at the interface between filler and epoxy.

  • The purposes of this study are to investigate water content and treatment period in Solid Matrix Priming(SMP; method for enhanced rapid and uniform seedling emergence in tobacco seeds). The higher water content made the faster imbibition speed of tobacco seed. But the radicle emergence shorten the period of water equilibrium. The range of water content in SMP treatment within the limits of no radicle emergence of tobacco seed was 28∼32% to dry weight of tobacco seed. The rate of radicle emergence and seedling emergence was higher in water content 30% and 40% treatment plot than that in 50% and 60% treatment plot. But it was not different between SMP treatment and non-SMP treatment. In water content 40% during 9 days treatment, germinative energy was highest, and T50 and mean germination time(MGT) were the shortest. The germination speed was higher in SMP treatment than that in non-SMP treatment. It was not different on the germination rate between non-SMP treatment and SMP treatment.

  • This study investigated the effects of pectinase treatment and skin contact time on the quality characteristics of Dae-hong peach wine. Wine was produced with variations in enzyme treatment and skin contact time (1 hour, 2 hours, 1 day, 2 days, and until the completion of fermentation). Enzyme treatment increased the production yield by 6%, as well as ethanol and redness levels, compared to the non-treated control. Volatile components were higher when the skin contact time was 2 hours or 1 day. Results were compared according to enzyme treatment and skin contact time and found to be influenced by methanol and 3-methyl-1-butanol. Enzyme treatment effectively enhanced yields and volatile compound contents. However, skin contact should be concluded a day before 1 day to ensure compliance with methanol legislative requirements. Therefore, our findings show that enzymatic treatment with shorter skin contact time preserves the distinctive characteristics of Dae-hong peaches and ensures the production of safe and flavorful wine.

  • Aebaegeum has been widely used in the treatment of epistaxis, as based on Oriental Medical 1iteratures. In order to investigate experimentally the clinical effects of Aebaegeum, hemostatic time, plasma recalcification time and prothrombin time of hypoprothrombinemia induced by warfarin injection, action on isolated ileum, action on blood vessel, action on blood pressure and respiration and action on heart were observed. The result of the studies were obtained as follows: 1. Hemostatic time of vein ruptured mice was significantly shortened. 2. Plasma recalification time and prothrombin time of hypoprothrombinemic rats induced by warfarin injection were significantly shortened. 3. Spontaneous mobilities in the isolated ileum of mice were significantly suppressed, and contraction by acetylcholine chloride and barium chloride were inhibited. 4. Dilatation of blood vessel and downing of blood pressure of rabbit were noted. 5. Contraction of heart in the original position and isolated heart of frog were significantly shortened. According to the above result, it is expected that Aebaegeum can be widely applicable to the treatment of epistaxis.
