수령독재 하에서는 수령 지위를 차지하고자 하는 권력 투쟁은 존재하지 않는다. 그러나 수평적으로 주요 기관과 엘리트 개인의 권력과 이권의 지분을 확대하기 위한 경쟁이 존재한다. 이러한 경쟁은 수령에 대한 ‘충성경쟁’이라는 외피를 갖는다. 권력 세습 기간 동안 이러한 경쟁이 현저히 증가한다. 권력 세습은 수령독재가 기반하는 통치연합을 재편성하는 과정이기 때문이다. 김정일에서 김정은으로의 권력 세습 과정에서 기관과 엘리트 사이에 권력 및 이권 관련경쟁에서 두 가지가 두드러지게 나타났다. 그 하나는 권력 세습 과정에서의 주도적 세력이 되고자 하는 경쟁 즉 후견권을 둘러싼 경쟁이다. 그 다른 하나는 기관별로 권력과 이권의 지분을 확대하기 위한 경쟁이다. 장성택은 이 두 가지 경쟁에서 모두 주역이었다. 그의 숙청도 이와 관련되어 있었다. Under the Suryong dictatorship, by definition, there is no political completion for Suryong`s status. There are, however, horizontal competitions to expand power and interest carried out by major power organizations and elites. Apparently they are loyalty competition devoted to the Suryong. During the power succession, as the ruling coalition is reconstructed, they intensify themselves. Two features have been pronounced during the hereditary succession from Kim Jong-il to Kim Jong-un in regard to competition for power and interest among power organizations and elites: the one is the competition for regency, i.e. to advance oneself as the dominant force in the promotion of the power succession; the other is the competition for increasing share of power and interest by power organizations and elites. Jang Sung-taek has stood in the center of these two competitions and he was purge thereof.

The workplace exposure of chemicals has steadily increased, therefore the concern for subsequent effect on reproductive outcome has been an important issue in occupational medicine. In previous studies, higher rates of spontaneous abortion, reduced fertility and menstrual disorder among women, and an impairement of sperm quantity and quality among men have been associated with a wide variety of chemical agents. This study was conducted to evaluate the effects of toluene, xylene and trichloroethylene(TCE) injection on the mRNA levels of GnRH, GnRH receptor and Pit-1 genes in male rats hypothalamus and pituitary and the effects on the plasma levels of FSH, LH, prolactin and testosterone. Sprague-Dawley male rats were divided into five groups of five each according to concentration of toluene, xylene and TCE. The rats were injected subcutaneously to 0, 50, 100, 200, 400 mg/kg body weight/day of toluene, xylene and TCE, respectively for 6 days. Rat brains were excised and hypothalamus and pituitary were separated. Reverse transcription-polymerase chain reaction (RT-PCR) and RNase protection assay(RPA) were used to evaluate the GnRH, GnRH receptor and Pit-1 mRNA levels. Plasma concentrations of FSH, LH, prolactin and testosterone were assayed by radioimmunoassay(RIA). The results were as follows; 1. GnRH, GnRH receptor and Pit-1 mRNA levels in toluene and xylene injected groups, and GnRH receptor mRNA levels in TCE injected group were lowered dose-dependently. Especially, GnRH receptor and Pit-1 mRNA levels in 200mg/kg of toluene injected group, and GnRH, GnRH receptor and Pit-1 mRNA levels in 400mg/kg of toluene injected group were significantly lower than control group (p<0.05). GnRH receptor and Pit-1 mRNA levels in 400mg/kg of xylene injected group, and GnRH receptor mRNA levels in 400mg/kg of TCE injected group were significantly lower than control group(p<0.05). 2. The plasma levels of prolactin and testosterone in 400mg/kg of toluene injected group, and LH in 100, 200 and 400mg/kg of xylene injected group, and testosterone in 400 mg/kg of TCE injected group were significantly lower than control group(p<0.05). In conclusion, we speculated that toluene and xylene affected reproductive system secondarily through hypothalamus-pituitary axis, and TCE affected directly through steroidogenesis. And we recommended that further study for assessment of the reproductive toxicity of mixed organic solvent exposures should be conducted.

In 3 months randomized, double-blind, vehicle-controlled study of retinol (vitamin A 0.1%-3000IU/g) in the treatment of photoaging skin, especially eye wrinkles. 24 patients applied retinol contained cream to the both eye wrinkles and vehicle cream(placebo) to the same site. Half of the patients received retinol contained cream and half received vehicle cream(placebo). All 24 patients who completed the study showed statistically significant improvement in photoaging eye wrinkles on the retinol contained cream treated group, but not on the vehicle treated group. Eight of the 12 patients who received retinol contained cream to eye wrinkles had improvement in photoaging, whereas only three of the 12 patients who received vehicle cream(placebo) improved. In retinol contained cream group, there is a some relationship between water contents and effects. In other words, as water contents were the higher, effects were the better. The side effects were limited to mild irritation of retinol contained cream treated skin. Retinol contained cream appeared to be safe and effective in the treatment of eye wrinkles.

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 4 years(2004-2007), and compared with retrospective study during former 10 years(1992-1996, 1999-2003) in Dept. OMS Pusan National University Hospital. We assessed the cause, type, demographic, etc, and analyzed alterations of facial bone fractures during past 3 periods. The results were as follows. The total number of patients was increased. 429 patients treated for maxillofacial fractures between January 1992 and December 1996, 466 patients treated between January 1992 and December 1996 and 764 patients treated between January 2004 and December 2007. The male-to-female ratio were 4.6:1, 3.9:1, and 4.16:1, respectively. Patient in the age groups of 10-19 years and 20-29 years increased in the latter two periods. Assaults and falls are decreased gradually, but slip down s are increased. Traffic accidents are still major cause of facial trauma. The mandibular fractures showed the highest incidence thorought three periods. Symphysis fractures of mandible was increased and condyle fractures of mandible was drecreased in the third period.

Diamond-like carbon(DLC) thin films have been fabricated by pulsed laser deposition method with various deposition parameters. The characterization of fabricated thin films was performed depending on the deposition parameters. As the kinetic energy provided by deposition temperature and the laser energy density were increased, the film showed graphite properties. Structural properties of the films were investigated by Raman spectroscopy. The growth energy should be optimized to fabricate high quality DLC thin films. DLC films showed high hardness and their friction coefficients were measured to be about 0.2 regardless of the load of the ball pin.

This study aims at providing useful data for the design of underground stations through an extensive survey of acoustic properties in underground stations in Seoul. In order to improve the sound efficiency at the underground station, sound characteristics in the space of the underground station were studied. Architectural features of underground stations located in Seoul were examined by visiting every site and analyzing drawings. The distinction in architectural features of this study resulted in the line-side section, the shape of under-platform section and ceiling material. Number of underground stations was selected and categorized based on architectural features, such as line-side section, the shape of platform section and ceiling material. Each selected station was revisited and the noise levels were measured and compared with the architectural features. The study found that the Sum-Sik type is more efficient than the one of the Sang-Dae-Sik type, which can be used for subway stations. The semi-circular section for the railway-side seems to contribute on the attenuation of noise transmitting from trains to the platform. In addition, the aluminum absorbing panel, net luber and zinc plate (panel 40% and net 60%) as ceiling meterial are more efficient than the horizontal aluminum spendral panel, vertical aluminum spendral panel with line and zinc plate (panel 40% and net 60%), respectively.

This study was carried out to evaluate the aberrant expression of ?? protein using immunohistochemical method in 10 malignant melanoma and 10 melanocytic nevi. Eight out of 10(80%) and two out of 10(20%) showed positive reaction in the nucleus of malignant melanoma and benign melanocytic nevi, respectively. In conclusion, the demonstration of ?? protein in benign melanocytic nevi greatly hinders the possibility of a diagnostic use of ?? immunostaining in differentiating malignant melanoma from benign melanocytic nevi.
