This paper aims to provide the educational data through the analyses of The Family Ritual Code and The Healthy Family Ritual Code for the settlement of the healthy family rites. The results of this study are as follows : 1. The Family Ritual Code contains the processes of the rites of passage. 2. The Family Ritual Code upon amendment, considers and respects the situation and self-control of the individual and one's family. 3. It also is one of the historical themes which have been intended to rationalize the procedures of the family rites, get rid of the empty formalities and vanity, and promote the healthy social spirit.

‘Cheongdam’ is a japonica rice variety developed from a cross between SR19200-HB826-34, a line of good germination ability and shoot emergence at low temperature and Juanbyeo, good quality and direct-seeding adaptable cultivar by the rice breeding team of National Institute of Crop Science, RDA in 2006. This variety has 153 days of total growth duration from seeding to maturity in direct-seeding, and 160 days of growth duration from seeding to maturity in transplanting. This is erect plant type with culm length of 74 cm, thick culm, and green leaves. It has large panicle shape with 126 and 140 spikelets per panicle in direct-seeding and transplanting, respectively. Milled rice is transluscent and medium in grain size of non-glutinous endosperm. This variety is susceptible to leaf and neck blast, bacterial blight, stripe virus disease and brown planthopper. The yield potential of ‘Cheongdam’ is 5.84 MT/ha at ordinary transplanting culture and 5.62 MT/ha and 5.89 MT/ha at wet direct-seeding and dry direct-seeding cultures, respectively in the local adaptability test for three years. ‘Cheongdam’ would be adaptable to middle and southern plain of Korea for direct-seeding culture and transplanting rice culture. ‘청담’은 중부지방 적응 중생 직파적성 품종을 육성할 목적으로 SR19200-HB826-34와 ‘주안벼’를 인공교배하여 2003년에 SR22320-3-4-1-2-1을 ‘수원498호’로 계통명을 2004년부 터 2006년까지 3년간 지역적응시험을 실시한 결과, 그 우수성이 인정되어 2006년 12월 직무육성 신품종 선정위원회에서 국가목록등재품종으로 선정됨과 동시에 ‘청담’으로 명명 하였는바, 그 주요 특성을 요약하면 다음과 같다. 1. ‘청담’의 평균출수기는 직파재배에서 8월 14일경으로 ‘주안벼’와 같은 중생종이다. 2. 간장이 74 cm정도로 줄기가 굵고 강인하여 도복에 비교적 잘 견디고 평균 수당립수는 직파에서 126개로 이삭이 큰 수중형이다. 3. 도열병, 흰잎마름병, 바이러스병 및 멸구류와 매미충에 대해 약하다. 4. 저온 출아성이 비교적 좋으며 장해형 내냉성은 중강정도이다. 5. ‘청담’은 현미천립중은 21.1 g인 중립종이고, 도정관련 특성이 우수하며, 특히 백미완전립율이 ‘주안벼’보다 우수하다. 6. 쌀 수량은 지역적응시험의 담수직파재배에서 5.62 MT/ ha, 건답직파에서 5.89 MT/ha로 평균 5.76 MT/ha의 수량성을 보여 ‘주안벼’ 대비 5% 증수되었고, 이앙재배에서 5.84 MT/ha로 ‘화성벼’보다 8% 증수되었다. 7. ‘청담’은 중부 및 남부 평야지에 알맞다.

본 논문에서는 다양한 재생환경에 대해 적응적으로 홀로그램 비디오를 서비스하기 위한 처리 기술에 대해서 논의하고, 새로운 알고리즘을 제안한다. 제안하는 알고리즘은 홀로그램의 생성 및 획득 방식에 따라서 해상도 스케일러블 코딩(hologram-based resolutional scalable coding, HRS) 방식과 광원 기반의 SNR 스케일러블 코딩(light source-based SNR scalable coding, LSS) 방식으로 구성된다. HRS는 이미 획득된 홀로그램에 대한 스케일러블 코딩 기법이고, LSS는 홀로그램을 만들기 이전의 광원에 대해 적용이 가능한 코딩 기법이다. 1,024×1,024 크기의 홀로그램에 대해서 HRS는 1:1에서 100:1의 압축률을 가지면서 8 단계의 적응적인 서비스가 가능하도록 하였다. LSS는 무손실 압축 기법을 사용하면서 광원 정보의 분리개수에 따른 서비스가 가능하도록 하였다. 제안한 방식을 통해서 다양한 해상도를 갖는 디스플레이, 수신단의 연산 능력, 그리고 네트워크의 대역폭에 따라 적응적으로 홀로그래픽 비디오를 서비스할 수 있다는 것을 보였다. In this paper, we discuss and propose a new algorithm of coding technique for scalably servicing holographic video in various decoding environment. The proposed algorithm consists of the hologram-based resolution scalable coding (HRS) and the light source-based SNR scalable coding (LSS). They are classified by the method generating and capturing hologram. HRS is a scalable coding technique for the optically captured hologram and LSS is one for the light source before generating hologram. HRS can provide the scalable service of 8 steps with the compression ratio from 1:1 to 100:1 for a 1,024×1,024 hologram. LSS can also provide the various service depending on the number of the light source division using lossless compression. The proposed techniques showed the scalable holographic video service according to the display with the various resolutions, computational power of the receiving equipment, and the network bandwidth.

In the anterior maxillary area, dental implants for tooth replacement are challenging due to the need to satisfy high esthetic level as well as functionality. Immediate implant placement and provisionalization can dramatically reduce the edentulous period, and then fulfill patient’s demand for esthetics. The aim of present case report is to demonstrate two cases that successfully restored single tooth with immediate implant placement and provisionalization in the anterior maxillary area. A 47 years old female was scheduled to replace her maxillary right central incisor due to crown-root fracture by trauma. Another 54-year-old female was planned to place dental implant following tooth extraction of maxillary right lateral incisor owing to continuous pus discharge despite repetitive treatments including apicoectomy. In these two cases, surgical and prosthetic procedures progressed in a similar way. After minimal flap elevation, atraumatic tooth extraction was performed. Implant was placed in proper 3-dimensional position and angulation with primary stability. Bone graft or guided bone regeneration for peri-implant bone defect was conducted simultaneously. Provisionalization without occlusal loading was carried out at the same day. Each definitive crown was delivered at 7 and 5 months after the surgery. Two cases have been followed uneventfully for 2 to 5 years of loading time. In conclusion, Immediate implant placement and provisionalization could lead to esthetic outcome for single tooth replacement with dental implant under proper case selection.
