Objectives The purpose of this study was to examine the current situation and the limitations of the Mental Health Review Board and to identify the effectiveness of the community linkage for discharged patients. Methods The data was collected from the 116 patients who were discharged from August 2005 to July 2007 by the order of the Mental Health Review Board. The survey was conducted by telephone with using a structured questionnaire. Results 51 patients (44.0%) were able to be referred to community mental health services when they discharged. The readmission rate was 50.9% and the mean duration to the first readmission was 51.73 days (S.D.=103.5). The mean duration to the first readmission was significantly longer for the group that was referred to community services and that had a negative correlation with the stability of health security. The outpatient maintenance rate and the current admission status were also significantly different between the group that was referred to community services and the group that was not referred. Conclusion The activities of the mental health review board have definite limitations in Korea such as the high rate of immediate readmissions after the discharge orders. A hospital-community integrated service system could be one possible solution to improve the maintenance of mental health patients in the community and to prevent their readmission.

The air quality has been deteriorated dux to the rapid industrialization and the increase of traffic volume. Especially, the concentrations of air pollutants of Saha-Gu including Shinp'yong-Jangrim industrial complex showed severe air pollution level compared to other districts in Pusan. To establish proper and comprehensive cnntrol strategies for the reduction of air pollutant levels, the information on the emission quantities of air pollutants are necessarily needed. Although there are a few data on the emissions of air pollutants of various sourxes, the data have not been used enough dux to the deficiency of quality and content. Therefore, it is nexessary to establesh the data system of emission inventory for the purpose of being used in air quality management. In this study, the database program of emissions inventory was made using the clipper version 5.2 program. The major functions of datavase program are to estimate the emission quantities and contributions of air pollutants by the grid, the source scale, the source type, and the season in Saha-Gu.

쇄골 중간 1/3 부위의 골절은 치료 결과가 양호하여 보존적 치료가 원칙적으로 받아 들어지고 잇으며 불유합에 대한 빈도도 낮은 것으로 되어 있다. 그러나 최근 전위 및 단축의 정도가 심할 경우 높은 불유합의 결과와 불량한 임상 결과를 보고하고 있어 이런 예에 대해선 수술적 치료를 권장하고 있다. 저자들은 단축 및 전위의 정도와 불유합의 연관성을 알아보고자 하였다. 연구 대상 및 방법 : 1993년 2월부터 2002년 1월까지 본원에 내원 했던 성인 중간부 쇄골 골절 환자 194명 중 완전 전위를 보인 78례를 조사하여 이중 63례를 대상으로 분석하여 후 향적 연구를 시행하였다. 4개월 추시 후에도 방사성 사진상 유합 소견이 관찰되지 않으면 불유합의 유의성을 알아보고자 하였다. 결 과 : 63례 중 불유합 및 지연 유합을 소견을 보인 환자는 15(23%)례였다. 골유합을 보인 48례의 단축은 평균 8.6㎜(2㎜-17㎜)였고, 전위는 평균 9.7㎜(2-22㎜)였다 .불유합 및 지연 유합을 보였던 15례에서 단축은 평균 14.5㎜(3㎜-37㎜), 전위는 평균 17.3㎜(4-25㎜)였다. 18㎜이상 단축이 있었던 경우 불유합의 발생과는 통계학적으로 유의성을 나타내었고(Fisher's exact test, p<0.01), Chi-square test상 16㎜ 이상의 전위를 보였던 경우 불유합 발생과 통계학적으로 의미가 있었다(p<0.01). 결 론 : 쇄골 골절 특히 중간 1/3의 골절은 비교적 보존적 치료에 결과가 좋은 것으로 되어 있으나, 전위 및 단축이 심한 경우 불유합에 대한 가능성이 높이 때문에 보다 경과 관찰시 유합의 진행이 없으면 적극적인 치료를 고려해야한다. Purpose : Because the prognosis of the mid 1.3 clavicle fracture is good, the conservative treatment with a figure of 8 bandage is the gold standard and the nonunions are rare. However, recently surgical treatment is recommended when the shortening and displacement is severe because of the high nonunion rate and the poor clinical result. This study was undertaken to evaluate that the shortening and displacement at fracture site are associated with the development of nonunion. Materials and Methods : We analysed the 194 fractures of mid 1/3 clavicle in adults which had been treated conservatively from February 1993 to January 2002 and did the retrospective study. Of these, 78 cases were originally in the middle third of the clavicle and had been completely displaced. We reviewed 63 of these cases. The shortening and displacement at the fracture site was measured on the initial roentgenogram. And the analysis of the patients' chart was done for another predisposing nonunion factors. Nonunion and delayed union are considered to be present when there has been little or no progression of clinical or radiographic healing at a minimum of 4 months after injury. Results : 15 of the 63 cases had developed nonunion.. The average 8.6㎜(2㎜-17㎜) shortening and average 9.7㎜(2-22㎜) in the union patients. The average 14.5㎜(3㎜-37㎜) shortening and average 17.3㎜(4-25㎜) in the nonunion patients. We found that initial shortening ≥18㎜(Fisher's exact test, p<0.01) and initial displacement ≥ 16㎜(Chi-square test. p<0.01)at the fracture site were significantly associated with the development of nonunion. Conclusion : The conservative treatment with figure-80-bandage is the gold standard in the clavicle middle one third fracture. However, the nonunion is commonly occurs in the cases of more of severely shortened and displaced fractures. If there are no signs of callus formation and the patient complains of pain after several week, osteosynthesis should be considered.

Torque Ripple Reduction of IPMSM Applying Asymmetric Rotor Shape Under Certain Load Condition

Jung, Young-Hoon,Lim, Myung-Seop,Yoon, Myung-Hwan,Jeong, Jae-Sik,Hong, Jung-Pyo IEEE 2018 IEEE transactions on energy conversion Vol.33 No.1

<P>This paper proposes a new numerical formula and a design method to reduce the torque ripple while improving efficiency and the control performance of an interior permanent magnet synchronous motor. In previous studies, the inverse cosine function (ICF) has been used for torque ripple reduction by making the air gap flux density distribution sinusoidal under a no-load condition. However, in this paper, the advanced inverse cosine function (AICF) based on the ICF is proposed. It determines an asymmetric rotor shape for rendering the air gap flux density distribution sinusoidal, considering a certain load condition. In addition to the torque ripple reduction, lower peak values, the total harmonic distortion (THD) of the induced voltage, and a lower iron loss can be achieved by applying the AICF, compared to the other conventional methods. The lower peak value and THD of the induced voltage are important because they affect the control performance of the motor. The lower iron loss can also lead to a higher efficiency, particularly, in the high-speed region. To verify the validity of the proposed design method, the characteristics of 8-pole, 12-slot motors that have different rotor shapes are analyzed using finite element analysis and experiments.</P>

Myung-Pyo Jung,Hong-Hyun Park,Jae Young Choi,Yeon Ho Je 한국응용곤충학회 2012 한국응용곤충학회 학술대회논문집 Vol.2012 No.05

This study was conducted to investigate the insecticidal capacity of recombinant baculoviruses to Plutella xylostella and Spodoptera exigua larvae. For recombinant viruses, Bacillus thuringiensis cry1-5 crystal protein gene was introduced into the genome by fusion of polyhedrin-cry1-5 under the control of polyhedrin gene promoter. Recombinant AcPolh5-3006BiKTT and AcPolh5-3006 AvTox2 based on BiKTT and AvTox2, respectively, were constructed under the control of early promoter from Cotesia plutellae bracovirus. Mortality of S. exigua larvae was significantly higher when they fed on cabbage coated with ApEGFP (wild type) over 5.0×106 PIBs/ml. For AcPolh5-3006BiKTT and AcPolh5-3006AvTox2, mortality of P. xylostella and S. exigua larvae was significantly higher when they fed on cabbage coated with recombinant baculoviruses over 5.0×106 PIBs/ml and 1.0×104 PIBs/ml, respectively. The value of LD50 was lower in the treatments with AcPolh5-3006BiKTT (P. xylostella:1.2×106, S. exigua:1.3×104) or AcPolh5-3006AvTox2 (P. xylostella:2.3×106, S. exigua:1.4×104) than the treatments with ApEGFP (P. xylostella: not estimated, S. exigua:5.0×105). Survival time (ST50) of P. sylostella larvae was much shorter at AcPolh5-3006BiKTT (29.6h) than AcPolh5-3006AvTox2 (46.2h) while that of S. exigua larvae was much shorter at AcPolh5-3006AvTox2 (95.1h) than AcPolh5-3006BiKTT (101.9h) or ApEGFp (130.7h). The two recombinant baculoviruses were more effective in S. exigua larvae but slower speed of action.

Myung-Pyo Jung,Hea-Son Bang,Myung-Hyun Kim,Kee-Kyung Kang,Deog-Bae Lee 한국응용곤충학회 2011 Journal of Asia-Pacific Entomology Vol.14 No.3

This study was conducted to monitor the abundance and distribution of the ussur brown katydid, Paratlanticus ussuriensis in South Korea, and to gather basic information about potential outbreak areas of this species. P. ussuriensis sampleswere collected fromApril to July in2009 and 2010 using the transectmethod at the city or gun level. P. ussuriensis were identified in 86 cities or guns, and eight gunswere determined to be potential risk areas of P. ussuriensis outbreaks. The current distribution of P. ussuriensis is well matched with the distribution of broadleaf trees. Their distribution and population density are expected to increase due to the expanding distribution of Quercus spp., the major food source of P. ussuriensis.
