우울증은 매우 보편적인 정신병이다. 보건복지부에 따르면 지난해 우리나라 우울증 환자는 61만 3000명으로 전체 국민의 1.5%를 차지했다. 그러나 대부분의 환자들은 본인이 우울증인지도 모르거나 정신병원 진료 기록이 남는다는 이유로 치료를 거부하여 상태를 악화시키는 경우가 적잖다. 그럴 때 다른 이의 도움이 필요하나 정신적인 질환은 겉으로 봐서는 알아차리기가 어렵고 폐쇄적인 우울증 환자의 특성상 직접 만나는 등의 물리적인 도움을 주기는 많이 어려운 것이 사실이다. 그래서 우리는 인터넷이라는, 가장 광범위하고 가장 긴밀한 플랫폼을 통하여 이런 우울증 환자들에게 다가가고자 '선플 로봇'을 고안하게 되었다.

The traditional methodology of online game development is separating server development module and cilent development module. However developing and maintaining expenses have been increased a lot due to duplicated modules such as definitions of network protocols and managements of planning data. In this paper, we suggest an advanced methodology of online game development based on the integrated single module with client and server. Its effectiveness was shown by applying the proposed methodology in the development of the online game 'Chungmukong's Battle on the Sea'. In this case, the project size was reduced by 15.1% by using the integrated single module with client and server.

Existing internet auction systems have adopted the form which gives a win to the auction bidder who proposes the top bid price for the goods posted on the auction board. But they haven't been satisfying the automatical one-step processing for user's convenience because they must require continuous care of user for bidding and checking as well as neglecting the convenience of user interface while participating in the electronic bidding system. The AuctionBot system of Michigan Univ. is known as the representative internet auction system. It has merit allowing the various kids of bidding. But it does not support automatic a process which can replaces what user has to do using an agent. To improve this kind of user interface, we propose an automatic bidding price strategy algorithm which composes the auction system using agent and design for auto-bidding system using agent so that I can replace user's bidding activity. This mechanism gives an auction system the efficient bidding price strategy.

This study supports the introduction policy of the MSO and Profit-making corporation by reviewing, and is intend to reviewing the analysis of policy measures activation in the digital age. The Medical industry is changing at a fast pace, and it is becoming fierce, In that flow, our nation has been giving efforts to the Medical industry in its bot qualitative growth and quantitative growth. However, we are laggard in our policy to activity such as the MSO and Profit-making corporation. It is true that there exists arguing on introducing market economy into the Medical industry, but we need a sound the activity policy which can extend over those negative perspectives.

Objectives : This study explored the clinical differences in attention-deficit hyperactivity disorder (ADHD) patients with and without developmental coordination disorder (DCD). Methods : Participants were 49 children and adolescents with ages between 6 and 18 years. These subjects were placed into 2 groups: ADHD without DCD (24) and ADHD with DCD (25). We used several evaluation tools on both groups: the Affective Disorders and Schizophrenia-Present and Lifetime Version- Korean Version (K-SADS-PL), Wechsler Intelligence Scale for Children-III (WISC-IIII), Child Behavior Check List (CBCL), Korean Personality Rating Scale for Children (K-PRC), and Bruininks-Osretsky Test of Motor (BOT-2). Results : Patients with both ADHD and DCD had a lower performance intelligence quotient and more internal and external behavioral symptoms than patients with ADHD but not DCD. It is possible that patients with ADHD and motor coordination problems should be noticed earlier and given intensive treatment.

Cha, Jong Whan (Dept. of Biology, Graduate School, Dong Kuk Univ.) The changes of chemical properties of forest soils in dry and wet seasons. Kor. Jour. Bot. VII(2): 1-8, 1964. Soil selected for the present investigation was collected from a mountain of the Forestry Experiment Station of the vicinity of Seoul. The forest communities studied were three forest and a unplanted soils. The soil samples were obtained from each forest type during dry and wet seasons. And these samples were collected from four horizons of all communities respectively. It was showed that exchangeable hydrogen was increased by rainfall, and total exchangeable base decreased in the same way. The content of nitrogen is washed away by rainfall, especially ammonium nitrogen was highly significant between dry and wet season. On the contrary, organic matter and available phosphorus were of no significant difference between dry and wet seasons. The values of pH appeared a different response in dry and wet seasons according to the plant communities. The needle-leaved forest soils showed more acidity than the broad-leaved forest soils, and the least acidity in open places. All nutrients in soil studied gradually decreased down the profiles. According to statistical analyses of the soil components among all soil horizons, total exchangeable bases in wet season indicated only significant at 1%. Exchangeable hydrogen and organic matter of the soil in dry season was particularly very low with increased depth in the profile. The fertility level of most forested soils selected for the present investigation is low according to chemical tests for available nutrient elements.

Prescribed according to the occupational safety and health low noise measurement method was changed to personal sampling in the method to measure an area noise. Such method had the limit which did not evaluated characteristic of sound of occurrence and the place of origin. This study was peformed to establish an engineering remedy of the work-place noise. The subject was a vibration control process of the place of business in Pusan. A simulation program applied for an engineering improvement of the work-place noise. The results were as follows: 1. An noise occurrence level of the work-place before improvement was $88^{\sim}97dB(A)$, We applied an improvement method to be established and were expected to $80^{\sim}l19dB(A)$, 2. The level of the noise-distribution to appear in the place of origin of the work-place before improvement was $90^{\sim}93dB(A)$ but, We executed the simulation after applied an engineering remedy and predicted $80^{\sim}85dB(A)$. A result of the simulation blue part was changed mostly into the dark blue color. The results suggest that simulation program establishes an engineering remedy and is useful to the case to apply.

Game bots distribute a large amount of goods or items used in a game, thereby lowering the value of game goods and items. Also, a large number of game bots hunt monsters and collect items, which hinders ordinary users from enjoying content normally. However, no research has been done on the type of user and the type of activity that the increase in bots specifically affects. Therefore, this study provides a practical implication to encourage users to use games by classifying types based on the game users' access data and analyzing the correlation with user departure due to the increase of bots.

This study showed the activation of public library services utilizing twitter. Top five American public library twitter's 1,373 tweets collected, analyzed by content types and examined applicability into public library services. Based on the results, it suggested that public library services can be activated by auto-tweeting informations within home page, re-tweeting of timely informations, generating HASH tag, using diverse social medias, active re-tweeting/replying, and utilizing twitter programs such as twit-bot. Finally, the study proposed that evaluations about twitter services such as satisfaction survey should be carried out.

컴퓨터 및 인터넷의 대중화가 급속도로 이루어지면서 전자상거래의 한 부분인 전자경매에 대한 관심과 개발이 상당부분 이루어지고 있다. 웹을 통한 전자경매의 발달로 직접 경매장에 가지 않고서도 적은 비용으로 다양한 상품들을 구매 및 판매할 수 있으므로 소비자와 공급자 모두에게 편의성과 이익을 제공해 주고 있다. 한편 에이전트에 대한 관심이 높아지면서 전자경매 시스템에 이를 적용하여 경매참여자의 편의성과 효율성을 증대시키려는 노력들도 활발히 이루어지고 있다. 대표적인 에이전트 기반 전자경매 시스템으로는 미국 워싱턴대학의 eMediator, 미시건대학의 AuctionBot, 스웨덴의 FishMarket 등이 있다. 이들 시스템들은 지원하는 경매유형, 입찰가격정책, 상품유형, 경매대상, 에이전트의 역할 및 기능등에서 상당한 차이를 보이고 있다. 본 논문에서 제안하는 전자경매시스템은 특히 경매참여자인 사용자의 편의성과 경매관리 및 운영의 안정성을 목표로 하고 있다. 에이전트 기반의 전자경매 시스템을 개발함으로써 기본적으로 사용자 인터페이스를 통한 경매참여와 사용자가 직접 에이전트를 생성하여 이동시킴으로써 경매에 참여하는 방법을 제공한다. 두 방법 모두 참여자가 직접 경매에 참여하는 것이 아니고 에이전트를 통해 언제 어디서나 경매에 참여하여 원하는 가격대로 상품을 구매하거나 팔 수 있도록 시스템을 개발하는데 목적이 있다.
