$La_{2/3}TiO_3$, $La_2Ti_2O_7$는 유전성을 갖는 특징으로 인해 여러 분야에 이용되고 있다. 본 연구는 perovskite 구조의 $La_{2/3}TiO_3$와 pyrochlore 구조의 $La_2Ti_2O_7$를 모체로 하여 $Al^{3+},\;Pr^{3+}$가 첨가된 형광체의 발광 특성을 알아보고자 하였다. 두 구조 모두 $Pr^{3+}의\;^1D_2{\rightarrow}^3H_4$ 전이에 의한 적색 발광을 나타내었다. 본 연구에서는 perovskite 구조의 $La_{2/3}TiO_3$:Pr 형광체의 에너지 전이 과정과 그 임계거리에 대한 조를 통해 에너지 전달체로서의 $Al^{3+}$의 역할을 제시하였다. 또한, perovskite 구조의 $La_{2/3}TiO_3$와 pyrochlore 구조의 $La_2Ti_2O_7$ 사이의 발광특성 차이를 알아보기 위해서 trap-involved process와 charge transfer band를 조사하였다. $La_{2/3}TiO_3$, $La_2Ti_2O_7$ are used in various parts by dielectric properties. The purpose of the present study is to understand the photoluminescence properties of $Al^{3+}\;and\;Pr^{3+}$ doped perovskite-type $La_{2/3}TiO_3$ and pyrochlore-type $La_2Ti_2O_7$ phosphor, which characterized by the red emission $(^1D_2{\rightarrow}^3H_4)\;of\;Pr^{3+}$ of $Pr^{3+}$ ion. The explanation for the energy transfer and the corresponding critical distance were proposed on the role of Al^3+ ions as energy transfer mediates in perovskite-type $La_{2/3}TiO_3$:Pr phosphor. In order to clarify the distinction of photoluminescence propoerties between the perovskite-type $La_{2/3}TiO_3$ and the pyrochlore $La_2Ti_2O_7$, the trap-involved process and the charge transfer band have been investigated.

Ajuba is a number of proteins containing cytosolic LIM domain. Its function may provide a new pathway whereby cell-cell adhesive events are transmitted to the nucleus to regulate cell proliferation and differentiation decisions. Here, Ajuba gene expression was investigated its molecular properties associated with endoplasmic reticulum (ER) stresses (tunicamycin, DTT, A23187 and BFA) which induced remarkable ex-pression of Ajuba mRNA. The mRNA half life of Ajuba was also determined, its half life of Ajuba mRNA in FRTL-5 cells was approximately 2 hr after the initial translation. Although the obvious bioligical function of Ajuba is not clear, on the base of the results, Ajuba gene expression is deeply associated with ER stresses.

수박작물의 대목용으로 사용하는 수박공대에 CGiMMV-CP 유전자를 도입하여 개발된 LM 수박공대의 CGMMV 내성 정도를 격리하우스와 노지 포장내에서 조사하였다. 격리온실에서의 $T_{3}$ 형질전환 수박대목의 CGMMV 내성은 접종 후 70일까지 유지되는 반면 대조구는 접종 후 20일에 전부 이병되었다. 인위적 토양전염 포장에서 형질전환체는 접종후71일까지 약 40%의 내성률을 보였으며, 대조구는 접종 후 37일에 모두 이병되었다. 인위적 접촉전염 포장에서 형질전환체는 대조구에 비해 약 10일 정도 지연효과를 보였다. 따라서 CGMMV-CP 형질전환체는 CGMMV에 저항성을 가진 것이 아니라 감염시기를 지연시키는 부분 내성으로 나타났다. CGMMV-CP homozygous T 세대를 진전시켜서 형질전환 수박공대 계통을 $BC_{1}T_{5}$ 세대에서 선발하였다. 또한 LM 수박공대에 형질전환 되지 않은 접수 (슈퍼금천수박)를 접목하여 non-LM 수박을 생산하고 CGMMV-CP 유전자에 관련된 물질의 이동 여부를 조사하였다. PCR, northern, western 분석한 결과 수박공대 대목에서 형성되는 DNA, RNA, protein 물질이 접수로 이동되지 않음을 확인하였다. Previously developed transgenic watermelon rootstocks (gongdae) inserted by CGMMV-CP were examined to test the virus tolerance levels. In the restricted plastic house, the $T_{3}$ watermelon rootstock showed tolerance to CGMMV until 70 days after inoculation on the leaves while the non-transformed watermelon rootstock became susceptible at 20 days after inoculation. In the field, tolerance efficiency of transgenic rootstocks maintained up to 40% at 71 days after contamination with CGMMV in the soil while all of the non-transformed rootstocks became susceptible at 37 days with the same condition. In the same field, transgenic rootstocks showed more tolerance to CGMMV than the non-transformed rootstocks as those were inoculated on the leaves, but it showed only 10 days delay before being susceptible. Therefore, transgenic rootstocks have a characteristic of delay effect against CGMMV susceptibility, rather than resistance character. From $T_{3}$ rootstocks homozygous for the CGMMV-CP horticulturally favorable individuals were selected for further breeding and a transgenic line was finally obtained at the $BC_{1}T_{5}$. A material transfer experiment was conducted to find out if the DNA, RNA or expressed protein in the transgenic rootstocks could move to the grafted scion (non-transformed watermelon, Super-Kumcheon). PCR, northern, and western blot analysis were performed and no evidence of transferring of those materials from rootstock to scion was ever found.

Since 1970, rapid economic growth and urbanization has gain speed in Korea and the supply of urban housing increased in its quantity. Although there is a lack of community space for residents' social life, it appears that the residents continuously pursuit luxurious town-house, which has advantages as low-density and low-rise building. These town-houses should settle as a community in a way to provide long time dwelling, pleasant environment and humane interaction among residents. The aim of this study is to analyze spatial composition of various types of townhouse and the effects of housing complex's space on residents' community activity conforming to the increase in community senses in complexes. Literature survey indicated that city region, suburbs, suburban leisure type housing and suburban style housing were major categories according to the complex's characteristics. According to the building code and zoning, under city region and suburbs, the classification explored row house, single house, leisure house, and sharing wall type house. Characteristics of the community space and the space organization were explored according to the type of houses. The planning guideline were also suggested for the design of townhouse complex in order to activate the community according to city region town house and single houses, suburb town house, and leisure type.

In this investigation, 480 high school students attending school in Seoul, Incheon were surveyed for their knowledge of seaweed and their preference of seaweed products provided during school meal service. Female students answered that they preferred seaweed more than male students. When asked to explain their preference for seaweed, most students who preferred seaweed responded `it is tasty` (82.9%), while those that did not like seaweed responded `I don`t like the texture when chewing it and it is not tasty` (47.8%). Most students reported that they usually eat `laver`, and the number of times that they at seaweed was `3-4 times a week`. The primary place in which they ate seaweed and the place where they feel it had the best taste was a `house`. The primary source of information regarding seaweed was mass media including TV, newspapers, magazines and the internet (48.8%). With regard to seaweed in school meals, which is offered twice a week, most students reported, `I eat seaweed and leave it to some extent.` They perceived `laver` to be most often provided in school meals, and 57.7% reported that their favorite seaweed meal was `laver`. When asked why they dislike seaweed in school meals, the most common responses were `I didn`t like seaweed the first time I tried it` (27%) and `Its taste is different from what I eat at home` (24.6%). The most common request regarding seaweed provided in school lunches was for the taste to be improved (48.2%). Evaluation of the preference for seaweed menus in school meals revealed that both males and females had higher preferences of more than 4 points for `fried laver` and `broiled laver`.
