  • Korea adopted feed-in-tariff system to disseminate the renewable energy generation in 2002, and amended twice this system in October 2003 and October 2004. It is weil known that feed-in-tariff system have been made with noticeable results in Europe countries. In Korea, however, there are many debatable issues about Korea's feed-in-tariff system, such as tariff level, operational period(the term of guarantee). assessment techniques This paper surveys and re-considers several problems and issues which have been discussed during the last two years.

  • A simplified TAC method was developed for the selection of solar atmospheric transmittance data fundamental to the calculation of design solar radiation for the peak cooling load calculation using ETD method. The summer and autumn solar atmospheric transmittance data of the 11 major cities in Korea were obtained. Based on the simplified TAC method, the atmospheric transmittance data were selected by the TAC 2.5% of July instead of the TAC 2.5% of June through September for summer and the TAC 5.0% of October instead of the TAC 2.5% of October and November for autumn. Results show that the atmospheric transmittance data at solar noon were in the range of 0.61-0.66 for summer and 0.78-0.82 for autumn except for Pusan and Incheon.

  • China Coastal Water (CCW) usually appears in the seas surrounding Jeju Island annually (June?October) and is very pronounced in August. The power spectrum density (PSD), sea level anomalies (SLAs), and sea surface temperatures (SSTs) were found to peak annually and semiannually. The peaks at intervals of 80-, 60-, and 43-days are considered to be influenced by CCW and the Kuroshio Current. Generally, low-salinity water appears to the west of Jeju Island from June through October and gradually propagates to the east, where CCW meets the Tsushima Current. Empirical orthogonal function (EOF) analysis of SLAs and SSTs indicated that the variance in SLAs and SSTs was 55.70 and 98.09% in the first mode, respectively. The PSD for the first mode of EOF analysis of SLAs was stronger in the western than in the eastern waters because of the influence of CCW. The PSD for the EOF analysis of SSTs was similar in all areas (the Yangtze Estuary and the waters to the west and east of Jeju Island), with a period of approximately 260 days.

  • Between October 1987 and October 1990, 6 patients underwent pharyngolaryngoesophagectomy with transhiatal gastric transposition and pharyngogastrostomy for hypopharyngeal and recurred laryngeal cancer. All patients had squamous cell carcinoma and were male, with age range from 54 to 67 years. Two patients had been treated initially by chemotherapy, but the tumor had persisted. One patient had been treated by radiotherapy and operation, but tumor had recurred in hypopharynx. There was no operative death. Major complications were anastomotic leakage in three cases, wound disruption in four cases and one postoperative bleeding. Anastomotic leakage was recovered in two cases with conservative management. The average hospital day was 33 days postoperatively. We conclude that reconstruction of the pharynx and cervical esophagus with gastric transposition is one of the recommendable procedures for extensive resection of pharynx or cervical esophagus with acceptable morbidity and functional recovery.

  • Daily and seasonal variations of the ambient gamma ray exposure rates were measured by using a pressurized ion chamber from January 2003 to December 2005 in the CheongJu Regional Radiation Monitoring Post and the patterns of the distributions were studied. The annual average of the daily variation of the exposure rate was $\sim0.17{\mu}R/h$. The exposure rate was found to be maximum during 8:00 am to 9:00 am and minimum during 8:00 pm to 10:00 pm. For the annual data, the exposure rate was the minimum during the month of February. The exposure rate increased from February to mid-October (except during the period from May to July with no change) and decreased from October to February. The seasonal variation was found to be about $1{\mu}R/h$. Most of the measured values (96%) of the exposure rates fell under the normal distribution with a deviation of less than 4.8% and the remaining 4% had large fluctuations caused mainly by the rainfalls.

  • Leaf blight outbreak was investigated in sweet persimmon tree orchards in Korea during a three-year period from 1995 to 1997. The man percentage of sweet perismmon leaves blighted by Pestalotiopsis theae was 15.9%. The highest disease incidence was surveyed to 20% in Milryang. The disease began from early June to late October, and peaked in September and October. The lesion size on leaf ranged mainly 1-3 cm. The typical symptoms were large grayish concentric lesions of oval patterns of either mesophyll or margin of the leaf, and olde trees were more susceptible than younger ones.

  • The Lion Air JT610 accident in Indonesia in October 2018, along with the Ethiopian Airline ET302 accident in March 2019, is an significant aircraft accident that detects defects of the B737MAX aircraft. Shortly after the accident, the FAA prohibited operation of the aircraft. This action has affected the market environment of airlines and aircraft manufacturers around the world. In October 2019, Indonesian Traffic Safety Committee released an accident investigation report for Lion Air JT610, which concluded that the causes of the accident were MCAS design defects, lack of education and training, and errors in the repair process. This paper summarizes the flight control system of the B737MAX aircraft, the causes of the accident based on the final accident investigation report, and provides considerations for aircraft design and retrofit.

  • Four times of field survey were carried out to collect fish samples at six stations in Shinpo district, North Korea in October 1997, July 1998, May and October 2002. Sampling stations were located in upstream, middle and down of the southern river of Bukchong and three brackish lakes of lake Hommanpo, Daein and Hyunkum, respectively. A total of 29 species belonging to 11 families occurred. Family Cyprinidae showed the prosperity in species number of 28% among total species occurred. No natural monument fishes or rare species were captured. Ten commercial fishes, five anadromous ones and five brackish ones were identified. Feeding habits divided fish fauna with 11 carnivores, two herbivores and seven omnivorous ones. In the river, 20 species belonging to seven families inhabited, 18 species of 6 families in lake Homanpo, 21 of seven III Hyunkum and 23 of eight in Daein, respectively. Ecological indices of richness, diversity and evenness were highest in lake Daein and dominance index was highest in lake Hyunkum.
