주택수요는 수요유발 상관인자를 주축으로 한 주택수요 예측모형에 의하여 그 수표량을 예측할 수 있다. 이때, 주택수요 예측모형은 상관인자의 영향도에 따라서 인자의 미세한 추이변화에 대해서도 수요의 변화폭을 민감하게 제시하게 된다. 이를 위하여 주택수요 예측에 동원 될 수 있는 여러 상관인자들 가운데 영향도가 가장 큰 인자가 무엇인지 찾아낼 필요가 있다. 이때 대상인자의 데이터는 횡단면자료(Cross Section Data) 혹은 시계열자료(Time Series Data)분석으로 수행된다. 즉, 영향도가 가장 큰 인자들을 찾아내는 방법마련이 필요하며 이후 이 방법에 따른 상관인자의 도출이 가능함에 따라 영향도가 가장 큰 인자를 발굴하는 방법을 제시하고 이에 의한 상관인자를 도출하는 것을 본 연구의 목적으로 한다.

This study has a purpose that definitize correlationship of spatial structure and sales strategies in mixed-use complexes which established in Korea since year 2000. For this purpose, this study tries to analysis spatial structure of mixed-use facilities through space syntax theory and makes an typological categorization based on their space composition. As a result of categorization, Korean mixed-use facilities can be classed as three types. First type is integrated stacking type. Second one is parallel connecting type. Third type is room to room type. According to differences between categories, their spatial structures show different meaning with different sales strategies. Integrated stacking type sales luxury brands and expensive stuffs and it also has deep and complicated structure. That means theses spaces usually make a strategy of exclusion. Parallel connecting type sales special categories and it also has shallow and easy spatial structure. That means these facilities want to make a smooth connection between apposed volumes. Room to room type sales cheap and fancy objects and it also has simple and shallow structure. That means simple spatial structure can be lead contact customer to stuffs. These results mean spatial structure have a effect on design of sales space.

This survey was carried out to investigate the temperature, pH value, nitrogen (ammonia, nitrite, nitrate), turbidity, color, chloride ion, $KMnO_4$ consumed, and hardness as chemical analysis of the tap water in Seoul city area during the period from September to Octobor, 1979, and to observe the differences among the values by the distance from the water purification plant and by the district supplied tap water from-the each water purification plant. The results obtained were as follows: 1) An average of the water temperature was $19.8\pm 0.2\circ$C. 2) An average of pH was $7.18\pm 0.02$. The difference among each district was statistically significant (p<0.01), but it was not observed among each distance. 3) An average of turbidity was $1.25\pm 0.12$ ppm. The difference among each district was highly significant (p<0.01), respectively, but not among each distance. 4) An average of color was $1.43\pm 0.16$ ppm, and there were statistically significant differences by the distance and by the district (p<0.01). 5) An average of ammonia nitrogen was $0.022\pm 0.005$ ppm. The differences among each distance, and district were statistically significant (P<0.01). 6) An average of nitrite nitrogen was $0.0050\pm 0.0013$ ppm, and the difference among each distance was highly significant (p<0.01), respectively, and each district showed statistical significance (p<0.01). 7) An average of nitrate nitrogen was $0.82\pm 0.08$ ppm. The difference among each district was significant (p<0.05), and each distance showed high significance (p<0.01). 8) An average of $KMnO_4$ consumed was $3.73\pm 0.16$ ppm, and the difference among each district was significant (p<0.05), but it was not observed among each distance. 9) An average of chloride ion was $8.56\pm 0.28$ ppm, and the difference among each district was higly significant (p<0.01), respectively, but it was not observed among each distance. 10) An average of hardness was $40.69\pm 1.17$ ppm, and there was statistically significant difference by each district (P<0.01), but not by distance. 11) The interrelation between temperature and pH of the tap water revealed the negative correlation from the coefficient of it as showed r=-0.6073 and p<0.01. 12) Except water temperature, there were negative correlationships between pH and other water qualities. 13) Correlation coefficients of $KMnO_4$ comsumed and ammonia nitrogen, nitrite nitrogen were statistically significant but that of $KMnO_4$ consumed and nitrate nitrogen showed no statistical correlationship. 14) Ammonia nitrogen seems to have high correlationship with nitrite nitrogen(r= +0.6669), but not with nitrate nitrogen. 15) Nitrate nitrogen seems to have statistically significant correlationship with nitrite nitrogen (r=+0.4959), but not with ammonia nitrogen. 16) The interrelation between chloride ion and hardness of the tap water revealed positive correlation from the coefficient of it as showed as r=+0.4888 and p<0.01.

We investigated the reproductive cycle with gonadal development of the female Cyclina sinensis by histological observations and seasonal changes in biochemical components of the adductor muscle and visceral mass tissues were studied by biochemical analysis, from January to December, 2001. The reproductive cycle of this species can be classified into five successive stages: early active stage (February to April), late active stage (March to June), ripe stage (May to August), partially spawned stage (July to October) and spent/inactive stage (September to February). Total protein contents in the adductor muscle tissues reached the maximum in February (early active stage) and appeared the minimum in June (ripe stage), while their contents in the visceral mass tissues reached the maximum in the late active and ripe stages (June) and gradually decreased from July (partially spawned stage) to November (spent/inactive stage). Changes in total protein contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.499, p = 0.099). Total lipid contents in the adductor muscle tissues reached the maximum in January (the inactive stages) and their contents gradually decreased from February. Their contents in the visceral mass tissues, however, reached the maximum in June (late active and ripe stage) and gradually decreased from July (the partially spawned stage). On the whole, total lipid contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.631, p < 0.05). Therefore, These results indicate that the nutrient contents of the adductor muscle and visceral muscle tissues change in response to gonadal energy needs. Glycogen contents in the adductor muscle tissue reached the maximum in March (early and late active stages) and decreased from July to September (partially spawned stage). while their contents in the visceral mass tissues reached the maximum in June (late active and ripe stages) and gradually decreased from July (partially spawned stage). Thereafter, their levels gradually increased in November (spent/inactive stage). On the whole, changes in glycogen contents appeared negative correlationship between the adductor muscle and visceral mass tissues. However, they showed no significant different (r = -0.307, p = 0.331).

This study was carried out to investigate the heavy metal contents and their correlationship between paddy soil and brown rice near the Kum-River area. In this study, eighty soil samples and forty brown rice samples were taken from the paddy soil. The contents of heavy metals were measured by flame atomic absorption spectrophotometry. The results were as follows: 1. The average contents of soluble heavy metals in surface soil were Cd 0.19, Cu 15.31, Zn 18.10 and Pb 9.08 ppm. The average contents of soluble heavy metals in subsurface soil were Cd 0.19, Cu 14.52, Zn 17.75 and Pb 8.11 ppm. There was no statistically significant difference between the two layers. 2. The contens of Cu, Zn and Pb of Taejeon(S6) and Cd of Sinbyung(S5) in surface soil were higher than those of other areas. The contents of Cd and Cu of Taejeon(S6) and Zn and Pb of Kumnam(S3) in brown rice were higher than those of other areas and four heavy metals in soil and brown rice of Simchon(S7) were lower than those of other areas. 3. The ratio of soluble contents(Cd:Cu:Zn:Pb) in surface soil was 1:79:93:47, that of soluble contents in subsurface soil was 1:76:94:43, and that of total contents in brown rice was 1:84:294:12. 4. The correlationship of the content between soluble heavy metals in surface(0-15 cm depth) soil total heavy metals in brown rice was found to be order of Cd>Cu>Zn>Pb. The correlationship of the content between soluble heavy metals in subsurface(20-30 cm depth) soil and total heavy metals in brownricewasfoundtobeorderofcu>Cd>Zn>Pb.

공정이 특정 허용범위 내에서 생산을 할 수 있는 지 여부를 결정하는 데 공정능력지수가 사용된다. 공정능력지수 $C_p$, $C_{pk}$ 그리고 $C_{pm}$ 등은 공정의 현황을 추적할 수 있는 활용성이 높은 관리도구로서 특별한 관심을 가진다. 대부분 공정능력지수에 대한 계산결과는 통계적 추정과 가설검정에 초점을 맞춘다. 따라서 $C_p$, $C_{pk}$ 그리고 $C_{pm}$의 추정치 ${\hat{C}}_p$, ${\hat{C}}_{pk}$ 그리고 ${\hat{C}}_{pm}$ 사이의 점근적 성질을 조사하는 것이 의미가 있을 것이다. 이 논문에서는 BN(${\mu}_x,{\mu}_y,{\sigma}^2_x,{\sigma}^2_y,{\rho}$) 하에서 세 가지 추정치 ${\hat{C}}_p$, ${\hat{C}}_{pk}$ 그리고 ${\hat{C}}_{pm}$ 간의 점근적 상관관계를 연구한다. 비정규성을 가진 공정에서는 두 종류의 공정능력지수 간에 상관관계를 정립할 수 있을 것이다.
