The evaluation of the quality of residential environment, in the planning process, is very important. If the environmental quality can be measured on the design scheme itself, it would be possible not only to estimate the residential environment, but also to apply the results of measuring in the planning and design of new residential projects. This study aimed at estimating the relative weights of the constituents of a residential environment by AHP (Analytic Hierarchy Process). For the detailed analysis of relative weights, the respondent of survey were composed of two different groups-dwellers and experts. The findings are as follows (:) 1) the relative weights of residential constituents were different between the respondent groups; 2) the relative weights of residential constituents were different according to socio-demographic characteristics; and 3) for the practical application of estimation results of the relative weights, the relation between residential performance constituents and physical design elements should be considered.

Through the combination of existing tidal prediction model and numerical tidal model, the efficient tidal prediction system was formulated and applied to the neighboring area of Pusan port. Because all tidal constituents for tidal prediction (69 tidal constituents are normally used) couldn't be considered due to the physical limits on computing process, some errors between the observed and predicted values were inevitably occurred. But it was confirmed that the computed values with maximum 10% of relative errors can be obtained if four major tidal constituents(M2, S2, K1, O1) are used. Thus, if other constituents than four major tidal constituents are additionally used, more accurate values will be obtained. Furthermore, if the database for harmonic constants in coastal waters is made in advance, using the numerical tidal model, prompt tidal prediction can be achieved at any time when it is required.

With the combination of existing tidal predictio model and numerical tidal model, the efficient tidal prediction system was formulated and applied to the neighboring area of Pusan port. Because all tidal constituents for prediction (normally 69 constituents are used) can't be considered due to difficulties on computing efforts, some errors between the observed and predicted values were inevitably occurred. But it was confirmed that the practical results with about 10% of relative errors were obtained if four major tidal constituents(M$_2$, S$_2$. $K_1$, $O_1$) are used at least. Thus, if other constituents than four major tidal constituents are additornaly used, more accurate results will be obtained . Furthermore, if the databases of harmonic constants in coastal waters is made in advance using the numberical tidal model, prompt tidal prediction could be achieved whenever required.

This expriment was carried out to get basic information on composition and yield of aromatic constituents in leaves of four medicinal plants, Angelica tenuissima, Chrysanthemum zawadskii. ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris. Volatile aromatic constituents, 28 compounds in Angelica tenuissima were identified and 19 compounds were indentified in Chrysanthemum zawadskii ssp. latilobum. Volatile aromatic constituents, 23 compounds in Artemisia iwayomogi and Artemisia capillaris were identified. Major volatile aromatic consitiuents analyzed by GC/MS in four plants were $\alpha$-pinene, camphene, sabinene, cis-2-hexanol, and camphor etc. Content of essential oils in Angelica tenuissima, Chrysanthemum zawadskii ssp. latilobum, Artemisia iwayomogi and Artemisia capillaris were 0.014, 0.275, 0.785, and 0.452%, respectively. As a result, it was suggested that a medicinal plant, Artemisia iwayomogi, was worthy of using as a useful material of perfume.

In natural language, it is common that repetitive constituents in an expression are to be left out and it is necessary to figure out the constituents omitted at analyzing the meaning of the sentence. This paper is on recognition of boundaries of parallel noun phrases by figuring out constituents omitted. Recognition of parallel noun phrases can greatly reduce complexity at the phase of sentence parsing. Moreover, in natural language information retrieval, recognition of noun with modifiers can play an important role in making indexes. We propose an unsupervised probabilistic model that identifies parallel cores as well as boundaries of parallel noun phrases conjoined by a conjunctive particle. It is based on the idea of swapping constituents, utilizing symmetry (two or more identical constituents are repeated) and reversibility (the order of constituents is changeable) in parallel structure. Semantic features of the modifiers around parallel noun phrase, are also used the probabilistic swapping model. The model is language-independent and in this paper presented on parallel noun phrases in Korean language. Experiment shows that our probabilistic model outperforms symmetry-based model and supervised machine learning based approaches.

The effect of protein constituents of six-year old fresh Panax ginseng root on chick embryonic brain, spinal cord and skeletal muscle dissociation cultures was studied. The protein constituents showed the enhancing effect on cultured brain, spinal cord and skeletal muscle cells. The neurite formation from brain and spinal cord cells and the outgrowth of neurite seemed to be enhanced by almost all of the protein constituents employed for this study. The maturation of skeletal muscle cells was stimulated by the protein constituents. This enhancing effect of the protein constituents was more vivid when brain, spinal cord and skeletal muscle cells were cultured with a medium which did not contain chick embryonic extracts known as an essential component for primary cell culture. The protein fraction having molecular weight range of 1,000 to 5,000 out of all the protein fractions employed for this study showed the most stimulatory effect on cultured brain, spinal cord and skeletal muscle cells.

The Four Major Rivers Restoration Project started in 2009 and completed in early 2013 is a large-scale inter-ministry SOC project investing ₩22.2 $10^{12}$ and one of the Project's objectives was to enhance the water-quality grade through recovering the river eco-system and environment. The average concentration and probability distribution of water-quality constituents at given and selected sampling sites are very significant elements for analyzing and controlling the water-quality of rivers or reservoirs effectively. Average concentration can be estimated by point estimator, distribution function of water-quality constituents or Bootstrap method, in which the distribution function estimated with more data in case of insufficient dataset, is applied. Ipo and Gangcheon water-quality monitoring stations in South Han River were selected to compare and analyze the variation of concentration before and after Ipo and Gangcheon Weirs construction, using the whole 4-year's data, from 2005 to 2008 and from 2014 to 2017. Water-quality constituents such as BOD and COD relating to oxygen demanding wastes and TP and Chlorophyll-a relating to the process of nutrient enrichment called eutrophication were also selected. The guidelines for water-quality control and management after weir construction including evaluation of water-quality constituents' variations can be presented by this paper.

우리나라 연안의 30개 조위관측소에서 관측된 조위자료를 조화분해하여 2021년에 대한 해역별 장주기 조석성분의 특성 및 장주기 조석성분이 총 수위 예측에 미치는 영향에 대해 알아보았다. 먼저 관측조위의 조화분해 결과, 우리나라 연안에서 장주기 조석성분은 연주조(Sa)와 반년주조(Ssa)가 우세하였으며, 해역별로는 서해안에서 약 17.8 cm의 상대적으로 큰 진폭을 보였다. 계속해서 총 수위 예측에 대한 영향을 살펴보고자, 2021년을 연구 기간으로 장주기 조석성분이 포함된 예측조위와 포함되지 않은 예측조위를 생산하였고, 각각의 예측조위를 폭풍해일 모델의 해일고 예측결과에 더하여 총 수위를 생산하였다. 장주기 조석성분을 고려하지 않은 총 수위와 고려한 총 수위의 오차를 비교한 결과, 전반적으로 뚜렷한 계절적 차이가 나타났다. 장주기 조석성분을 고려하지 않은 총 수위에 비해서, 장주기 성분이 고려된 총 수위는 여름철에는 오차가 큰 폭으로 감소하였고, 겨울철에는 강한 음의 편차를 보이며 오차가 증가하는 경향이 나타났다. 이는 우리나라 겨울철의 강한 고기압과 같은 기상현상에 의한 영향이 예측조위와 해일고 예측결과에 이중으로 반영되어 나타난 결과로 해석되었다. 해일고 예측결과를 조화분해하였을 때, 연주기 성분이 우세하였고 이를 장주기 조석성분이 고려된 총 수위에서 제거하였을 때, 특히 겨울철에 나타난 강한 음의 편차가 사라지고 연평균 RMSE도 감소하는 것으로 나타났다.
