CGI 프로그램에서 클라이언트와 서버의 자동화된 상태정보 전달
최준용,유진호,장종표,방만원 木浦大學校 情報産業硏究所 1997 情報産業硏究誌 Vol.5 No.-
The HTTP Protocol composed of WWW's client/server model is unconnected and not keep state, so, there is one connection for one request. In this condition, it has no guarantee to memory which is needed in sequential processing, and HTTP Protocol has no choices to transfer the information from client to server's CGI or the information exchange. This paper uses the word 'key' instead of this 'state information'. We studied the key which creates automatically the HTML document for data search hierarchically in WWW environment and to confirm applied this to multimedia order and sale system of agricultural and marine products.

1. 돌연변이체 DM-1과 DM-2의 간장은 양친인 Dohoku나 대구조인 흑진주벼보다 짧은 반면에 출수기는 7일내지 20일가량 늦어졌다. 2. 이들 DM-1과 DM-2의 수장은 대조구와 비슷하였으나 주당 이삭수는 대조구와 같이 DM-2에서 매우 많았다. 3. 선발된 계통들에 대한 주당 영화수는 대조구보다 적었으나 영색은 갈색내지 짙은 자주색으로 다양한 변이를 보였고 까락길이 역시 변이가 컸다. 4. 안토치안 색소에 대한 공시계통간 차이를 optical density(OD_(530))값으로 나타낸 결과 DM-2 변이계통에서 2.23, DM-3 변이계통에서 2.26으로 나타나 대조구인 흑진주벼의 2.59보다 크게 낮았다. Culm length of Dohoku mutant 1(DM 1) and mutant 2(DM 2) were shorter than Dohuko parent and Heukjinjubyo check, while days to heading were delayed seven to 20 days Panicle length of these were similar to check and number of panicle per plant of DM 2 was highly appeared than check. Spikelets per plant of the selected lines were lower than check, and glume color of these were varied from brown to dark purple and awn length was also varied according to line used. Anthocyanin content of each mutant line as measured by 530㎚ were lower than that of check in that OD 2.23 and OD 2.26 for DM 1 and DM 2, respectively, and 2.59 for check.

1. 새로 육성된 4개의 대덕찰 찰옥수수 교잡종에 대한 간장은 대조구인 찰옥 1호보다 큰 반면에 개화기는 약 4∼7일 늦었으며, 모든 공시 교잡종의 주당 분얼수는 한 개이하의 무효분얼로 나타났다. 2. 새로 육성된 대덕찰옥수수의 이삭길이와 직경은 대조구인 찰옥 1호보다 크게 나타났으며, 특히 대덕찰옥수수 1호와 2호의 과피두께는 대구조보다 얇았고, 당도 역시 높게 나타나 우수 교잡종으로 평가되었다. Stem height of the new developed "Daedekchals" waxy hybrids were higher than check hybrid. Chalok #1, while days to tasseling were delayed about four to seven days. Number of tillers per plant of the these new hybrids including check were appeared to be one less as non-effective tiller. Ear length and diameter of the new waxy hybrids were longer and thicker than check, respectively. In addition pericarp thickness of the Daedekchal #1 and #2 among new developed waxy hybrids were thinner and sugar content were higher than check.

공시 교잡종에 대한 각 지역에서 선발된 우수 교잡종의 간장 및 착수고는 대조구와 비슷한 경향이었으며, 생체 및 건물수량은 분얼수 및 간장과 관련이 큰 것으로 나타났으나 재식 밀도와 기상상태와도 밀접한 관계로 나타났다. 따라서 생체중은 대전지역에서 재배된 교잡종 H67이 대조구인 광안옥에 비해 53.2%로 높았고, 수원에서 역시 41.8%으로 높았으며, 종실수량은 H15과 H67에서 대조구보다 11.7%와 9.7%로 각각 높게 나타났다. 대전에서 분얼성인 H42와 무얼성인 H65에서 대조구보다 9.1%, 5.2%증가하였고, 수원에서는 분얼성이 H42와 무얼성인 H65에서 대조구보다 9.1%, 8.5% 증가하여 교잡종간, 지역간에 큰 차이를 보였다. 한편 후기 녹체성은 무얼형보다 분얼형에서 낮은 경향을 보였는데 SK계통과 교배된 조합에서 우수한 편으로 나타나 우수 교잡종 육성시 중요 고려사항으로 지적되었다. In order to develop the crude forage maize hybrids with high dry matter and grain yield, several hybrids evaluated as superior hybrids at three regions in 2001. They were planted and surveyed again for the second selection in 2002. The selected hybrids showed large difference in some major characteristics according to planting areas and dates(Suwon : April 25. Daejeon : May 15 and Milyang : May 25), but insect and disease injury were similar to check. Fresh and dry weight of the H67 hybrid at Suwon and Daejeon was the highest among hybrids including check, but low in Milyang due to raining after flowering. Grain yield was higher than check in H15 at Suwon H45 and H37 at Daejeon and H67 at Milyang.

Objectives : This study aims to estimate the prevalence of the DSM-IV psychiatric disorders in Korean population using the Korean version of Composite International Diagnostic Interview (K-CIDI). Methods : Subjects were selected by taking multi-stage, cluster samples of 7,867 adult household residents, 18 to 64 years of age, in ten catchment areas. Total 78 trained interviewers administered the K-CIDI to the selected respondents, from June 1 to November30,2001. Results : Total 6,275 respondents completed the interview. Some 33.5% of respondents reported at least one lifetime disorder, 20.6% reported at least one-year disorder, and 16.7% reported at least one-month disorder. The most common lifetime disorders were alcohol abuse/dependence (17.24%), nicotine dependence/withdrawal (11.19%), specific phobia (5.16%), and major de-pressive disorder (4.25%). The lifetime prevalence of substance abuse/dependence (0.25%) and schizophrenia (0.16%) was very low. Nicotine and alcohol use disorder showed very high male/female ratio. Mood disorder and anxiety disorder were more prevalent among female than male. Conclusion : The prevalence of psychiatric disorders was high. In comparison with other studies, remarkable differences in distributions of psychiatric disorders across the areas and times were observed.
MANET에서 종단간 통신지연 최소화를 위한 심층 강화학습 기반 분산 라우팅 알고리즘

In this paper, we propose a distributed routing algorithm for mobile ad hoc networks (MANET) where mobile devices can be utilized as relays for communication between remote source-destination nodes. The objective of the proposed algorithm is to minimize the end-to-end communication delay caused by transmission failure with deep channel fading. In each hop, the node needs to select the next relaying node by considering a tradeoff relationship between the link stability and forward link distance. Based on such feature, we formulate the problem with partially observable Markov decision process (MDP) and apply deep reinforcement learning to derive effective routing strategy for the formulated MDP. Simulation results show that the proposed algorithm outperforms other baseline schemes in terms of the average end-to-end delay.

It has been reported that some exercise could enhance the anti-viral antibody titers after vaccination including influenza and coronavirus disease 2019 vaccines. We developed SAT-008, a novel digital device, consists of physical activities and activities related to the autonomic nervous system. We assessed the feasibility of SAT-008 to boost host immunity after an influenza vaccination by a randomized, open-label, and controlled study on adults administered influenza vaccines in the previous year. Among 32 participants, the SAT-008 showed a significant increase in the anti-influenza antibody titers assessed by hemagglutination-inhibition test against antigen subtype B Yamagata lineage after 4 wk of vaccination and subtype B Victoria lineage after 12 wk (p<0.05). There was no difference in the antibody titers against subtype “A.” The SAT-008 also showed significant increase in the plasma cytokine levels of IL-10, IL-1β, and IL-6 at weeks 4 and 12 after the vaccination (p<0.05). A new approach using the digital device may boost host immunity against virus via vaccine adjuvant-like effects.
