According to the importance(production ratio) of special brand eggs, poultry farma can be classified into four types(Types I to IV). A close relation can be observed between these types and farm scale. Special brand eggs used to be the speciality of small-scale, suburban poultry farms. Recently, however, the production of these eggs has been adopted by medium and large farms, too, and is increasing throughout Japan. In particular, small-scale farms specializing in these eggs have attained a high profit and take a characteristic management from as opposed to large-scale poultry farming that adopts the \"small profit and quick returns\" strategy. Because of this, the meaning of special brand egg production to farm management differs according to farm scale. For small poultry farmers, it means securing a high profitability and for medium and large producers, improving the corporate image or meeting the needs for assortment of retailers.

교통약자의 이동편의 증진을 위해 도입된 특별교통수단은 2016년 법적 기준대수 충족 등 양적인 발전을 이루었으나, 대기시간의 50% 이상이 30분을 초과하는 등 질적인 측면에서 발전이 부족한 실정이다. 이에 본 연구에서는 특별교통수단의 운영 효율화를 위하여 대구광역시 특별교통수단 승하차 이력 자료 중 대기시간이 상위 25%에 해당하는 장기대기통행을 추출하여 공간자기상관 분석과 사회 연결망 분석을 수행하였다. 분석 결과 특별교통수단 이용자들의 평균 대기시간과 공간과의 상관관계는 높은 것으로 나타났으며, 일부 도서산간 지역에서 개선지역을 도출하였다. 내향연결 중심성 분석 결과 첨두시간대는 종합병원, 복지관 방문이 주를 이루는 반면, 비첨두시간대는 터미널/역사, 주거지 인근의 의원 방문의 장기대기수요가 높게 나타났다. 외향 연결 중심성 분석은 첨두시간대와 비첨두시간대 모두 주거지 기반의 수요가 높게 나타났다. 본 연구의 결과는 특별교통수단 운영의 질적 개선과 교통약자 이동권 개선에 기여할 것으로 판단되며, 연구의 학술적 함의와 한계점 또한 제시하였다.

부하예측의 경우 가장 중요한 문제는 특수일의 부하를 예측하는 것이고, 따라서 본 본문은 과거 특수일 부하 데이터를 이용하여 신경회로망 모델에 의해서 특수일 피크부하를 예측하는 방법을 제시한다. 특수일 부하는 예측되었고, 예측 오차율은 광복절을 제외하고는 l∼2% 정도의 비교적 우수한 예측결과를 도출하였다. 따라서 사용한 예측 모델은 특수일의 부하에 만족스러운 정밀한 예측이 가능하고. 신경회로망은 특수일 부하 예측의 결과를 검증하기 위해 4차 직교다항식모형과 특수일 부하의 예측에효과적인 패턴 변환비를 이용한 신경회로망 모형을 구성했다. 한편, 시간별 특수일의 부하예측에도 신경회로망을 적용한 특수일 부항예측의 경우와 같은 양호한 예측결과를 보였다.

An opportunity for dental students to come into contact with individuals with disabilities is insufficient. Therefore, prejudice and negative attitudes towards persons with disabilities persist. Working under the assumption that educating dental students regarding people with disabilities will bring about positive awareness, we conducted this study. We investigated the changes in the recognition of the issues and needs of people with disabilities before and after special care dentistry class of students of dental college that will include an experience in a dental clinic with a disabled person. Seventy-two Kyung Hee University School of Dentistry third-year dental students attended the special care dentistry class in one semester and they took the same survey was before and after the class. In the questionnaire, we used the disability factor scale (DFS) that Siller has proposed. The authoritarian virtuousness factor getting lower to a significant level after receiving an education. This means that after the education, the respondents realize that how hard to adapt the disabilities. After receiving an education, the rejection of intimacy factor score significantly get higher than before they took the class. This means that after the training, positive attitudes towards those with disabilities were better than those towards the opposite sex. We were able to confirm a positive change in the recognition for persons with disabilities through the special care dentistry class. Our study shows that educating dental students on the how to take care of individuals with disabilities can bring about a positive change in the attitudes students may have regarding them.

This study analyzes the characteristics of special configuration for wayfinding in general hospitals. To that end, the study categorizes four different hospitals, according to the type of their wayfinding systems. It aims at utilizing the result of the analysis for wayfinding system in general hospitals by applying three elements of analysis methods', perpetual access, depth, and intelligibility. The study result shows as follows: First, there is no difference in special hierarchy when hospitals are analyzed and divided by halls and streets. It means that outpatient departments are located by spatial function and characteristics rather than form of spatial configuration. Second, we found that fewer direction changes are conducive to easier circulation in terms of wayfinding, when we analyzed spatial depth from the main entrances to the outpatient departments. Third, regarding intelligibility, intelligibility of Chungang University Hospital ranked highest. Kunkook University Hospital, Dongkook University Hospital and Seoul National University Hospital ranked 2nd, 3rd, and 4th respectively. It means that difficulty level of wayfinding is not decided by the characteristics of special configuration such as hospital hall and hospital streets but depends on location planning. The difficulty level of wayfinding mainly relies on location planning.

A new code: LS code was proposed for IMT-2000 CDMA system. The code has special properties during a certain time of interval: 1) perfect autocorrelation 2) perfect crosscorrelation. The perfect autocorrelation means that the autocorrelation has nMaximum for zero time-offset and zero for other times during a certain time. Moreover the perfect crosscorrelation means that the crosscorrelation has zero during a time of interest. In the LAS-DMA system, the LS code is only used in the spreading of data bits in contrast to the conventional CDMA system. Therefore the LS code pair setting and allocation order should be dealt with carefully considering the special properties of LS code. This paper is intended as an investigation of the setting LS code pair and the sequential allocation method. Firstly, the optimum LS code pair set is proposed in order to minimize PAPR. Secondly, the sequential allocation method is studied to either minimize PAPR or expand IFW.
