This study was carried out to evaluate the status of the groundwater quality for paddy fields irrigation in Korea. Water samples were collected at 130 sites throughout the country. Samples were collected at three seasons-April, July and October-in 2000. According to our survey, the groundwater was found to be suitable for irrigation purpose. Average EC was shown 0.286 dS/m. Nitrate-nitrogen and Cl^(-) concentration was 5.6 ㎎/L, 32.95 ㎎/L which satisfied the Korean Standards for Irrigation Water. Nitrate-nitrogen concentration in each province was shown as following orders: Jeju (11.17 ㎎/L) > Chungnam (8.16 ㎎/L) > Gyeongbuk (6.64 ㎎/L) > Gyounggi (5.91 ㎎/L) > Chungnam (4.95 ㎎/L) > Gyeongnam (3.91 mgk) > Jeonbuk (3.50 ㎎/L) > Jeonnam (3.27 ㎎/L) > Gangwon (2.91 ㎎/L). The concentration by sampling seasons were October (6.62 ㎎/L) > July (5.88 mg&) > April (4.78㎎/L). As the soil of Jeju Province is usually derived from volcanic ash soils mainly used for upland drops, it may influence the nitrate-nitrogen concentration of groundwater. The amount of rainfall also influence the water quality. But the COD_(Cr), were shown April (3.17㎎/L) > July (2.91 ㎎/L) > October (2.40 ㎎/L), it is highly related in the basal dose of organic matter fertilizers. This study demonstrated that groundwater quality was suitable for irrigation, but continuous monitoring is recommended for agricultural policy and developing OECD agricultural environment indicators.

Selective posterior rhizotomy(SPR) has been known to reduce the spasticity as well as to improve the quality of life in patients with intractable spasticity. Twenty patients underwent SPR under intraoperative electrophysiological monitoring(IOM). Fifty-two percent of sacrolumbar rootlet were cut after electrical stimulation. Eighteen patients(90%) with spastic type of cerebral palsy showed marked reduction of spasticity and functional improvement without any complication. The patients who did not respond to SRP had mixed types of spasticity. IOM facilitate the selection of pathological rootlets regardless of anaesthetic level. intensity of electrical stimulation, and individual variability of responses. It is concluded that careful selection of surgical candidates and of pathological rootlets under IOM are important to reduce the spasticity. thereby to obtain a better outcome.

Mastoparan B (MPB)는 벌독으로부터 정제된 양친매성α-helical 구조를 취하면서 14개의 아미노산 잔기로 구성된 염기성 항균성 펩타이드로서 여러 가지 생물막과 작용한다. 본 연구에서는 우리 나라 연안의 적조 (HABs, harmful algal blooms)를 일으키는 4종의 적조생물 (Alexandrium tamarense, Chattonella catenatum)에 대한 MPB의 살조효과를 조사하였다. MPB의 4종의 적조생물에 대한 살조효과는 31.3㎍/㎖에서 세포의 lysis또는 ecdysis와 같은 형태로 현미경으로 관찰할 수 있었다. 또한 MPB는 C. marina 및 C. polykridorides에 대해서 A. tamarense와 G. catenatum보다 더욱 강한 살조효과를 나타내었다. 이러한 MPB의 HABs에 대한 살조효과연구는 새로운 살조물질을 개발하기 위한 자료가 될 것으로 생각된다. Mastoparan B (MPB), an antimicrobial cationic peptide isolated from the venom of the hornet Vespa basalis, is a basic amphipathic a-helical peptide composed of fourteen amino acid residues. In this study, we have investigated the algicidal effect of MPB against hatmful algae blooms (HABs) casative Alexandrium tamarense, Chattonella marina, Cochlodinium polykrikoides and Gymnodinium catenatum. The algicidal effect of MPB showed in the concentration of 31.3 ㎍/㎖ to 500 ㎍/㎖ against 4 HAB species and observed cell lysis or cell ecdysis by microscopy. MPB reacted more sensitive to C. marina and C.polykrikoides than A. tamarense and G. catenatum. The algicidal study of MPB against HABs will provides much insight into development of new algicidal substances.

According as it moves from the economy of liberalism to monopolistic economy in modern times, since the private monopolistic enterprise or a state's monopolistic project gradually started to control the economic society, modern law began to become different. This treatise only intended prove a change of content and essence in the feature of modern contracts. In chapter Ⅱ, it was introduced for a coincident contract and the content of compulsion of contract as a feature of the modern contract. Such a modern contract means the general public to be subordinate to large enterprise, and also because, management of enterprise on a large scale in monopolistic ecomony of today became very huge, there is a problem about that the existence which follows the general public's conditions become existensive, too. In chapter Ⅲ, it was introduced to the historical background of the theory of compulsion of contract and switch over existence-consideration. In chapter Ⅳ, it treated a special feature of the construction of contract in the territory of existence-consideration. The contract in this territory is a contract in large style and the mass of consumer can't take any freedom but for or against. Such a special feature can be found coincident or general conditions. In conclusion, use of transportion organs or main supply of commodity for our existence by monopolistic enterprise which is lawfully protected in the territory of existence-consideration or by monopolistic enterprise as a fact, should be carried out for all the persons' benefit.
항공사의 컴퓨터 예약시스템과 국내 여행업의 유통 네트워크에 관한 연구
김찬영,이윤철 한국항공대학교 경영연구소 2002 경영연구 Vol.9 No.1
본 연구는 항공사의 컴퓨터 예약 시스템의 발전과 여행시장의 유통경로 변화를 고찰하여 여행업의 유통전략과 유통경로의 방향성을 제시해 보려는 데 그 목적이 있다. 항공사 컴퓨터 예약시스템은 발전을 지속하였으나 1990년대에 들어와서는 Internet이 등장하여 항공사는 인터넷 시스템으로 고객과 직접 접촉하는 직접거래가 증가하고 있다. 이러한 상황에서 여행업은 항공사와 고객사이에서 유통경로의 역할을 할 분야를 찾아야 하며 관광업계가 같이 발전하기 위해서는 업무여행자 시장과 관광여행자 시장을 구분하여 여행업의 유통경로를 설정하는 방안을 제시하였다. The purpose of this study is to present a distribution strategy for traveling business and directivity of distribution channels by examining the development of the computerized reservation system for airline companies and the changes of distribution channels for traveling markets. The computerized reservation system for airline companies has been continued to develop, however, with the appearance of the internet in 1990s airline companies are making more transactions through direct contacts with clients by the internet system. It has been presented that in such circumstances a traveling business should find out the sectors in which they can play a role of the distribution channel between airline companies and their customers and in order that they may be developed together with the business circles of tourism the distribution channel of a traveling business should be set by dividing the travelers markets and leisure traveler markets.

This study was conducted to evaluate the temperature rise on the root surface while the root canal is being obturated using continuous wave of condensation technique. Maxillary central incisor was prepared for repeated canal obturation. Ten thermocouples (Omega Engineering Inc., Stanford, USA) were placed at 1mm increment from the anatomical root apex. The real temperature of Buchanan plugger was recorded before insertion into the root canal. The root canal was obturated with continuous wave of condensation technique as described by Buchanan and the root surface temperature was recorded during obturation at 150℃, 200℃, 250℃ and 300℃ temperature settings of System B HeatSource (Model 1005, Analytic technologies, Redmond, WA, USA). After completion of the temperature recording, the dentinal-cementum thickness at each sites was measured. The data were analyzed using one-way ANOVA followed by Scheffe's test and linear regression test. The results were as follows. 1. When the temperature was set at 150℃, 200℃, 250℃ and 300℃ on the digital display of System B HeatSource, the real temperature of the plugger at the 1mm point from the tip revealed 130.82±2.96℃ 158.00±5.26℃, 215.93±6.91℃ and 249.88±3.65℃ respectively. 2. The position of 8 mm from the anatomical apex showed the highest temperature increase at each temperature settings and it was significantly higher than those of other positions (p<0.01). The temperature rise was constantly increased toward coronal portion from apex of the root. 3. The maximum temperature increase on the root surface was 2.37±0.09℃ at 150℃ setting, 3.11±0.12℃ at 200℃ setting, 3.93±0.09℃ at 250℃ setting and 5.69±0.15℃ at 300℃ setting respectively. These results suggest that it be relatively kind to the supporting tissues of the root that the root canal is obturated using continuous wave of condensation technique at 150℃, 200℃, 250℃ and 300℃ temperature settings on digital temperature display of System B HeatSource.
