Objective: This study aims to investigate the immediate effects of myofascial release and Duoball assisted self-relaxation (DASR) techniques on pain and muscle tension in patients experiencing chronic cervical pain. Design: A randomized controlled trial. Methods: This study is a randomized controlled experimental study. Eighteen patients with chronic neck pain who met the selection criteria were randomly assigned to myofascial release group and myofascial release group using Duoball. Results: The frequency results for assessment muscle tension showed a decrease of about 10% in the suboccipital muscle, SCM, Pect m, UT, and LS in both the MFR and DASR groups, and the stiffness results showed a decrease in all muscles except the upper trapezius in the MFR group and the DASR group. All were found to decrease by about 10% in the suboccipital muscle, SCM, Pect m, UT, and LS, and the decrement results showed an increase of about 15% in the suboccipital muscle, SCM, Pect m, UT, and LS in both the MFR and DASR groups(p<0.05). Conclusions: In patients experiencing chronic neck pain, application of MFR and duoball assisted self relaxion was shown to be effective on pain and muscle tension. MFR is a non-pharmacological intervention method with few potential side effects and is considered a universal and easily applicable treatment method.

Objectives : This study was conducted to compare between hallucination group and delusion group in patient with schizophrenia, using Brain $^{99m}Tc$-ECD PECT. Methods : Among 16 patients with less than 3 schizophrenic episodes, 8 patients whose initial symptom was hallucination were assigned to the hallucination group, and other 8 patients with initial sumptom of delusion were assinged to the hallucination group. All of the patients clinically evaluated using the PANSS and BPRS. Both groups of patients and 8 healthy subjects underwent $^{99m}Tc$-ECD PECT. Results : Score of thinking disturbance subscale of BPRS were significantly lower in the hallucination group than the delusion group. In SPECT analysis, the hallucination group showed significantly increased perfusion in some areas of the right temporal lobe, bilateral limbic lobes and left parietal lobe compared to delusion group. Both group had a reduced rCBF in some areas of the frontal lobe. Conclusion : The hallucniation group, compared with the delusion group, showed significantly increased regional cerebral blood flow in some regions. Therefore, this data suggests that different neural substrates may affect the process of auditory hallucination and delusion.

Galectin-3 (Gal-3) is a carbohydrate-binding protein which is thought to be involved in cancer progression but its contribution to epithelial ovarian cancer (EOC) remains unclear. The present study sought to determine the role of Gal-3 in chemoresistance of the human SKOV-3 ovarian cancer cell line to paclitaxel (PTX) using recombinant human Gal-3 (rhGal-3) and PectaSol-C modified citrus pectin (Pect-MCP) as a specific Gal-3 competitive inhibitor. Our results showed 41% increased cell proliferation, 36% decreased caspase-3 activity and 33.6% increased substrate-dependent adhesion in the presence of rhGal-3 compared to the control case (p<0.001). Treatment of cells with a non-effective dose of PTX (100nM) and 0.1% Pect-MCP in combination revealed synergistic cytotoxic effects with 75% reduced cell viability and subsequent 3.9-fold increase in caspase-3 activity. Moreover, there was 39% decrease in substrate-dependent adhesion compared to control (p<0.001). These results suggest that inhibition of Gal-3 could be a useful therapeutic tool for combination therapy of ovarian cancer.

지자체 농업기술센터와 농과원에서 수집한 18개의 Bacillus subtilis 균주들이 보유하고 있는 기능성을 구명하기 위하여 항균활성을 비롯한 사이데로포아 생산, 질소고정능력, 인산가용화 능력 및 오옥신 생성능력을 조사하였다. B. subtilis 균주들은 대부분 입고병균(R. solani), 고추 탄저병균(C. acutatum), 채소류 시들음병균(F. oxysporum), 벼도열병균(M. oryzae), 고추 역병균(P. capsici)에 대하여 항균활성을 보였다. 대부분의 균주가 Siderophore와 오옥신 생성능력을 보였으며 질소고정능력도 함께 보유하고 있는 것으로 나타났다. 인산가용화능은 조사한 Bacillus 속 균주 중 단 한 균주에서 활성을 보였다. 대부분의 B. subtilis 균주가 고추 흰가루병 억제효과를 보였으나, 균주 간에는 방제효과에 있어서 큰 차이를 보이지 않았다. B. subtilis R2-1균주의 농업현장에서의 활용 가능성을 구명하기 위하여 2009년도에 강원도 화천의 유기재배농가에서 오이 흰가루병 방제용 미생물 농약으로 등록되어 사용되고 있는 '큐펙트'와 '탑시드'를 대조로 하여 방제효과를 검정하였다. 2009년도에 B. subtilis R2-1 처리시 방제효과는 37.7%로 '탑시드'(47.6%)보다는 낮았으나, '큐펙트'(25.7%)에 비해서는 높았다. 2010년도에는 B. subtilis R2-1의 고추 흰가루병 방제효과가 83.3%로 미생물 농약인 탑시드 보다도 높게 나타났다. B. subtilis R2-1균주의 발병억제 기작을 구명하기 위하여 B. subtilis R2-1균주와 미생물 농약(탑시드, 큐펙트)을 경엽 처리한 후 포자발아율을 계수한 결과, 미생물 농약인 큐펙트는 97.9%, 탑시드는 94.7% 억제하는데 비해서 B. subtilis R2-1균주는 84.2% 억제하는 것으로 나타났다. 앞으로 B. subtilis R2-1을 고농도로 배양할 수 있는 대량배양기술을 개발하고 항균활성 기능이 잘 발현되도록 제형화한다면 생물농약으로의 개발이 가능할 것으로 사료된다.

This paper is to study the characteristics of fabrics dyed with astringent unripe persimmon juice. The cotton silk rayon and nylon fabrics were dyed with astringet unripe persimmon juice. The structures of natural fabrics dyed fabrics and dyed fabrics followed by washing were examined by scanning electron mi-croscopy. Surface reflexibility of VIS trans-mittance of UV VIS and NIR were analyzed. The study conclues as follows: 1. Colour of cotton fabrics dyed with persim-mon juice became darkended as a function of exposing time to sunlight. That colour was chaged after washing. 2. Blocking effect of ultraciolet light and visible ray was increased in all dyed fabrics. Especially dyed cotton fabric blocked UV light perfectly and the blocking effect was still remained after 9 washings. 3. Persimmon juice dyeing produced coating effect to fabrics besides dyeing effect accord-ing to the scanning electron micrographs. In a word the cotton fabric dyed with per-simmon juice has blocking effect of UV light stiffness. Therefore I think persimmon juice dyeing is a very useful textile finishing and ex-pect a wide application of the technique in fu-ture.

Container handling facilities in Korean ports have increased rapidly according to Korean industrialization and the worldwide containerization. Over 98% of total containers handles in Korean ports are handled in Puan ports. This paper presents the estimation method of annual container handling capacity of container terminals by the computer simulation models. Simulation models are developed utilizing SIMAN IV simulation package. Annual handling capacity of real container terminals such as BCTOC and PECT was estimated by the proposed simulation models. Also, Annual handling capaicty of planned or expected terminals in Puan port was estimated. The comparisons between container forecast demand and estimated handling capacity of Pusan port from 1996 through 2001 were made. It showed that Pusan port will have over two million TEU handling capacity shortage during that period and will face enormous port congestion. Lastly, mid term and long-term capacity expansion plansof container terminals in korean ports were discussed.

This study is a research for an idea of costume containing clothing system in the early Practical Science School. The result are described as follows 1. Bak-Kyem, Han got a critical thought and attitude to seek for practical and rational as pect. Because that he studied an original text and wanted to find a basic meaning. And the result, he made a Pang-Ryeong Symeui. 2. Hwyeng-won, Rue contended that we had to model after chinese costume system to seek for a correct clothing system to harmonize with our culture and regulation. And he sought for the original courtesy because that his basic idea of reformation in the clothing system was an ancient system. But when there was a remedy, he suggested a new system. 3. Ik, lee considered a clothing system with a critical and investigated attitude. In the clothing system, he wanted to keep an original courtesy. But he asserted a constant reformation in evil tradition. He pursued a rationality not to be tied a formality, and he had also a flexibility to recognize real customs.

As the quantity of transported goods increases, there is a lot of mechanical trouble with loading facilities. So it tremendously produces not only economic loss but also time loss. To reduce the loss from the trouble of leading facilities, it is necessary to analyse the distribution of the problem's occurrence and use the analyzed data to minimize the outbreak of trouble. So the data can be usefully used when designing or manufacturing and it also can be utilized for proper maintenance of operating equipment, frequency of inspection and repair, know-how of checking on equipment and purchasing of spare parts. And it is possible to minimize the loss if the propel maintenance is adapted
