숭어과 어류는 연안에서부터 담수역까지 서식하고 있는 대표적인 광염성 어류이다. 이들의 형태적인 유사성 때문에 분류학적인 면에서나 명명법에 있어 많은 논란이 있다. 숭어과 어류 중 국내에서 주로 소비되고 있는 어종은 숭어(Mugil cephalus)와 가숭어(Chelon haematocheilus)로, 일반적으로 숭어와 가숭어를 구별하지 않고 숭어라 불리기도 한다. 이에 본 연구에서는 국내의 학술적인 자료 및 옛 문헌을 조사하여 국내에서 혼용되고 있는 숭어류의 학명 및 어명에 대해 정리해보고자 하였다. 숭어의 학명은 M. cephalus로 사용되고 있지만, 가숭어는 Chelon, Mugil, Liza 속명이 혼용되고 있다. 숭어류의 어명에 대해 국내사전에는 숭어와 가숭어를 구별하지 않고 있으나, 일어, 영어, 중국어사전에서는 숭어와 가숭어가 명확히 구분되어 있었다. 옛 문헌에서는 숭어류를 '치어' 또는 '수어'라 이르고 있다. 대부분의 문헌에서는 숭어와 가숭어의 구분이 명확하게 나타나지 않았으나, 자산어보에서는 가숭어를 치어(참치어)로, 숭어를 가치어로 기록하고 있어 '가(假)'자의 붙임이 현재와 달리 사용되고 있었다. 가숭어는 양식되고 있는 종으로 앞으로 산업적인 활용이 모색되고 있는 단계에서, '가'자에 대한 부정적인 인식을 고려하였을 때 가숭어라는 어명 대신에 '참숭어'로의 어명 변경을 제안한다. The mugilidae fishes are common euryhaline species that live in coastal marine waters to freshwater areas. The taxonomy and nomenclature of the mugilidae fishes still remain unresolved because of their morphological similarities. Among the mugilidae fishes, most commonly consumed in Korea, are grey mullet (Mugil cephalus) and red lip mullet (Chelon haematocheilus). It is generally called 'mullet' without distinguishing between two mullets. Therefore, the aim of this study is to examine the scientific names and common names of mullet species used in Korea from the domestic journals and Korean old documents. The scientific name of grey mullet is M. cephalus, but that of redlip mullet is C. haematocheilus. But the genus of redlip mullet is still mixed with Chelon, Mugil, and Liza. The standard name of two mullet is not distinguished in the Korean dictionary, but they were clearly distinguished in the Japanese, English, and Chinese dictionaries. In the ancient Korean references, the mullet was called 'Chieo' or 'Sueo'. In most of the old literature, the distinction between grey mullet and redlip mullet is not clear. However, in Jasaneobo, it was written separately from grey mullet and redlip mullet, and attaching "ga" was different from now. The Korean standard name of redlip mullet is 'gasungeo', however, the fishermen in Jeollado and Gyoungsangdo call it 'chamsungeo'. Considering the negative perception of 'ga' character, it is proposed to change 'cham(眞)' instead of 'ga(假)' to improve economic value of red lip mullet.

Dentin hypersensitivity must be one of the most frequent postoperative complaints in periodontal patients. Obliterating the open dentinal tubules or decreasing the diameter of their orifices would, therefore, be an objective of treatment for hypersensitive teeth. The purpose of this study was to evaluate the effect of a pulsed Nd:YAG laser irradiation on obliteration of dentinal tubules and to determine any difference according to irradiation methods. The 45 posterior teeth that had been extracted due to periodontal disease were initially treated with tetracycline HCI(100 mg/ml, 4 min.) to remove the smear layer after root planing. The root surfaces were then irradiated by a pulsed Nd:YAG laser(EL.EN.EN060, Italy) by different laser beam spot size and different exposure condition: ${\cdot}$ group 1: irradiated group by small spot(beam diameter=1mm, lW, 2 sec) ${\cdot}$ group 2: irradiated group by large spot(beam diameter=10mm, 1W, 200 sec) ${\cdot}$ group 3: irradiated group by gradual increase of watt (from 0.3W to 1.0W), beam diameter=4mm ${\cdot}$ group 4: irradiated group by fixed watt(1.0 W), beam diameter=4mm ${\cdot}$ control group: no irradiation but root planing and tetracycline HCI conditioning only. Additionally, the specimens were retreated with tetracycline HCI(100mg/ml, 4min.) to evaluate the stability of obliteration effect by Nd:YAG laser. Specimens were examined under the scanning electron microscope(JEOL, JSM-840A, Japan). Photomicrographs were taken at ${\times}4,000$ magnification and were analyzed statistically. The results were as follows: l. Scanning electron micrographs of root surface treated by tetracycline HCI alone(control group) showed widened, funnel-shaped dentinal tubules, while those of the root surface irradiated by various methods showed partially or completely obliterated dentinal tubules and various surface alterations, eg, flat, multiple pitted, melted and resolidified surface at the same energy density. 2. There was no significant difference in the obliteration effect of dentinal tubules between group 1 and group 2, and between group 3 and group 4(p>0.05). 3. The obliteration effect of dentinal tubules by a Nd:YAG laser irradiation was relatively stable to tetracycline HCI. The results demonstrate that a pulsed Nd:YAG laser irradiation within 1.0W, regardless of irradiation methods, can obliterate dentinal tubules effectively.

The purpose of this study is to review the operative management and outcome of operation for Crohn's disease. The medical records of 17 patients who underwent operations for Crohn's disease at Seoul National University Children's Hospital from January of 1988 to June of 2005 were reviewed. The male-to -female ratio was 1.8: 1. The median age at the onset of symptoms and the time of diagnosis was 9 years 6 months and 11 years 6 months respectively. The median time interval from diagnosis to operation was 2 years and 1 month (0 month~8 years). The ileocolic or ileocecal region was the most common site of involvement. The indications for operation were intractable symptoms (8 cases) and obstruction or stricture (7 cases). The median postoperative hospitalized days were 14.4 days (8~35 days). Five patients (29 %) experienced postoperative complications. Symptom free state or symptom relief was observed in 11 cases after surgery and 6 cases had intermittent episodes of remissions and recurrences. In pediatric Crohn's disease patients who present with intractable symptoms despite medical treatment or develop surgical complications, symptom free state or symptom relief can be achieved by minimal resection of the diseased segment.

A stochastic approach has been Presentde for superplastic deformation of Ti-6Al-4V alloy, and probability functions are used to model the heterogeneous phase distributions together with superplastic deformation behavior have been investigated by means of the probability functions. The results have shown that the probability changes during the deformation. The stress-strain behavior with the evolutions of probability function can be correctly predicted by the model. The finite element implementation using Monte Carlo simulation associated with phase re-distributions shows that better agreement with experimental data of failure strain on the test specimen.

In recent years, the power demand has been increasing steadily and the occurrence of maximum power demand has been moving from the summer season to the winter season in Korea. And since the control of electric power supply and demand is more important under those situations, a micro-grid system began to emerge as a keyword for the sTable operation of electric power system. A micro-gird power system is composed of various kinds of distributed generators(DG) such as small diesel generator, wind turbine, photo-voltaic generator and energy storage system(ESS). This paper introduces a method to determine the optimal capacities of the distributed generators which are installed in a stand-alone type of microgrid power system based on the fundamental proportion of diesel generator. At first, the fundamental proportion of diesel generator will be determined by changing from 0 to 50 percent. And then we will optimize the capacities of renewable energy resources and ESS according to load patterns. Lastly, after recalculating the capacity of ESS with consideration for SOC constraints, the optimal capacities of distributed generators will be decided.
