Dependent models in quality statistics are classified as serially autocorrelated model, multivariate model and dependent sample model. Dependent sample model is most efficient in time and cost to obtain samples among the above models. This paper proposes to implement parametric and nonparametric models into production system depended on demand pattern. Nonparametric models have distribution free and asymptotic distribution free techniques. Quality statistical models are classified into two categories ; the number of dependent sample and the type of data. The type of data consists of nominal, ordinal, interval and ratio data. The number of dependent sample divides into 2 samples and more than 3 samples.

There were many researches on marine transportation and granaries, most of which focused on the historical establishment and organization of the marine transportation. However, a few researches were conducted on the architectural aspects. Hence the purposes of this study are to investigate the following matters: first, documents and relics concerning the tribute granary castle at Cape Gongse in Asan, a typical granary during the Joseon Dynasty, were investigated to academically understand the castle's establishment and historical background; second, the dispositional characteristics of the granary and the castle, including its adjacent facilities, were investigated to review its archaeological value; finally, basic materials were provided for systematical preservation and management these relics. As for the research method, the author referred to and analyzed sundry records and old maps, and ascertained in detail historical evidence through residential testimonies and the on-the-spot surveys. In addition, the author investigated the dispositional characteristics of the tribute granary castle at Cape Gongse by analyzing its exact size and shape, based on the old documents and an actual survey of the castle remains. The characteristics of the tribute granary castle at Cape Gongse may be summarized as follows. First, tribute granary at cape Gongse is a only tribute granary which has a granary and castle. second, the tribute granary castle at Cape Gongse has a curvilinear shape, like a gourd dipper; a large circle surrounding the village and a small circle surrounding the area of Mt. Shinpoong both meet up with it. Third, the construction type of the tribute granary castle at Cape Gongse is in a style similar to a town castle or a battle camp castle located in the coastal regions. As for its locational conditions, however, the east gate, presumably an incoming and outgoing route to the granary for vessels, was a feature unique to the marine granary castle. Fourth, the tribute granary at Cape Gongse had a granary of eighty kan in 1523 and, in addition, there were also Bongsang-cheong, Sa-chang, Joseon-sobakcheo, Chimhae-dang, and more, not to mention many privates houses in the castle. The granary is located in the center of the tribute granary castle, where Gongse Nonghyub is currently located. The location of the government offices seemed to be on the northern ridge. Fifth, the tribute granary castle at Cape Gongse is a valuable relic that offers insight into marine transportation, tribute granaries, and tribute granary castles during the Joseon Dynasty. It has special archaeological value because it was one of only a few tribute granary castles that served to protect the tribute granaries.

This fundamental studies on for the productivity improvement and laborsaving of purse seine fishery. Given the difficulty posed from the distortion of net shape caused by the external forces, such as tide, at the time of shooting and pursing, we set the 4 steps of 0, 2, 4 and 6cm/sec in flow velocity in the flume tank for the experiment in order to examine those characteristics. We used two model seines designed on the scale of 1 to 180 based on the power block seine, which is the mackerel purse seine generally used in the near sea of Jeju Island and triplex seine, which is the mackerel purse seine of one boat system fishing expected in the future, for the experiment, and interpreted the characteristics of several motion in water, such as the shape of seine, the change in tension and area during pursing and its the analysis results are as follows. Though the experiment could be conducted up to 6cm/sec of flow velocity that was defined, the experiment could not go on because of the severe distortion in the seine at the flow velocity in excess of 6cm/sec. As for the depth of leadline and reduction rate of side area of seine when the pursing is connected, P seine turned out to be slightly higher than T seine, and the hauling speed and reduction rate of upper area of seine were found similar to each other. The correlation between the hauling time (Ht) and depth of lead line (Dhp, Dht) of P seine and T seine can be expressed by the equation, that is, Dhp=(0.99Pt-7.63)Pt+69.01, Dht=(1.03Pt-7.73)Pt+66.74. The correlation between the hauling time and hauling velocity (Hpp, Hpt) can be expressed by the equation, that is, Hpp=-0.06Ht2+0.88Ht+0.78, Hpt=-0.05Ht2+0.81Ht+0.98 here, Pt is pursing time. And the correlation between the pursing time and the reduction rate of side area (sArp, sArt) can be expressed by the equation, that is, sArp=-0.48Pt2+14.79Pt-16.74, sArt=-0.45Pt2+14.56Pt-16.48. The reduction rate of upper area of seine (tArp, tArt) can be expressed by the equation, that is, tArp=0.34Pt2-0.66Pt-0.74, tArt=0.34Pt2-0.27Pt-1.80. In addition, the correlation between the pursing time and tension of purse line (Tep, Tet) can be expressed by the equation, that is, Tep=2.79Pt2+2.26Pt-0.60, Tet=2.14Pt2+8.08Pt-27.50.

It is the basic studies for productivity improvement and laborsaving of purse seine fishery. Because the seine shape is apt to be transformed in seine shooting process due to the effect of tide, this study is intended to establish 4 steps, whose flow velocity are 0, 2, 4 and 6cm/sec, in flume tank and perform the experiment to review the character. We used two model seines designed on the scale of 1 to 180 based on the power block seine, which is the mackerel purse seine generally used in the near sea of Jeju Island and triplex seine, which is the mackerel purse seine of one boat system fishing expected in the future, for the experiment, analyzed of the sinking movements on the two seines and its results are as follows. In the setting over the flow velocity 6cm/sec, experiment was impossible because of flying and transformation of seine were severe. The sinking movements of P seine and T seine generally showed linear phenomenon and the sinking speed showed gentle curve shape. Sinking tendency was distinguished by existence of flow velocity. When there is flow velocity, it showed the phenomenon that it sinking by similar type. Although sinking depth and sinking speed did not show distinguished classification, P seine shows bigger than T seine. When there was in flow velocity, the elapsed time(Et) and sinking depth (PDp, TDp) of P seine and T seine can be shown such experimental equations as PDp=(0.21V+4.96)Et-(0.62V-0.10) and TDp=(0.19V+4.95)Et-(0.72V+0.34). When there was in flow velocity, the elapsed time and siking speed (PSp, TSp) of P seine and T seine can be shown such experimental equations as PSp=-0.11Et2+1.42Et+1.75 and TSp=-0.11Et2+1.41Et+1.37.

본 연구에서, 랜덤(r-) 및 블록(b-) 구조를 가지는 가교 공중합 폴리이미드를 N,N-bis(2-hyoxyethyl)-2-aminoethanesulfonic acid와 pentanediol을 가교제로 사용하여 제조하였다. 비교를 위하여 가교되지 않은 r- 과 b- 술폰화 공중합 폴리이미드도 제조하였다. 술폰산기의 조성에 강한 의존성을 보이는 이온교환능 값은 r- 과 b- 술폰화 공중합 폴리이미드에서 서로 비슷한 경향을 나타냈다. 카르복실산 기의 dimerization을 통한 물리적 가교현상은, 가교되지 않은 b- 술폰화 공중합 폴리이미드 고분자의 평균 사슬 거리를 감소시켰으며, 결과적으로 함수율과 메탄올 투과도를 r- 술폰화 공중합 폴리이미드보다 감소시켰다. 동시에, 고분자의 평균 사슬 거리의 감소는 단위 부피당 fixed-charged 이온의 함량을 증가시켰고, 이렇게 높아진 liked-charged 이온 밀도는 b- 술폰화 공중합 폴리이미드의 수소이온 전도도의 향상에 기여하였다. 가교제 및 고분자 구조에 상관없이, 가교구조의 도입은 고분자 사슬간의 평균 거리를 감소시켰고, 메탄올 투과도를 낮추었다. 반면에, 수소이온 전도도는 향상되는 경향을 나타내었는데, 이는 수소이온의 전달을 담당하는 친수성 채널이 효과적으로 형성 될 수 있기 때문이다. 특히, 이러한 경향은 술폰산기를 가진 가교제로 가교된, r- 술폰화 공중합 플리이미드에서 뚜렷하게 나타났다.

벤토나이트는 낮은 침투성, 높은 수착성, 자체밀봉특성, 내구성 등으로 인해 고준위 방사성 폐기물 처분을 위한 지하처분장에서 완충재 후보물질로 고려되고 있다. 적절한 처분장 조건에서 국내 Ca-벤토나이트에 대하여 지하수 침식에 의한 벤토나이트 입자의 발생 가능성과 발생된 벤토나이트 입자들의 영향에 대한 실험적 연구를 수행하였다. 실험결과 비록 벤토나이트의 팽윤압에 의한 암반 균열로의 벤토나이트의 침투는 적었지만 벤토나이트/화강암 경계에서 벤토나이트 입자가 발생될 수 있고 지하수 흐름에 의해 유동될 수 있음을 보였다. 압축된 벤토나이트 블록으로부터 이러한 벤토나이트 입자들의 유동화에는 각기 다른 과정들이 기여하고 있음을 확인하였다. 유량이 크면 클수록, 유출되는 벤토나이트 입자들의 농도가 높게 나타났다. 따라서 실험결과는 지하수 흐름에 의한 벤토나이트 표면의 침식은 침투과정과 함께 화강암 균열에서의 벤토나이트 입자들을 유동시키는 주요한 과정임을 보여준다.

목적 : 상자와 나무토막 검사는 손의 기능, 즉 조작능력을 평가하는 방법으로 보다 객관적이고 일상생활에서 많이 쓰는 손의 기능을 검사할 수 있는 가장 기본적이고 간단한 검사방법이다. 따라서 본 연구는 서울의 초등학생을 대상으로 일반적인 특성(성, 연령, 우세한 손)과 신체적인 특성(앉은키, 몸무게)에 따른 상자와 나무토막 검사의 정상아동 표준치를 제시하여서, 아동 치료에 기초가 되는 자료를 제공하고자 하였다.연구방법 : 연구 대상자는 서울에 위치한 한 초등학교에 다니는 남학생 85명(45.2%), 여학생 103명(54.8%)으로 전체 188명이였다. 자료는 8세에서 13세까지 6집단으로 나누고, 평균, 표준편차, 백분위 점수로 나타내었다.결과 : 상자와 나무토막 검사에서 평균값은 성별, 연령, 우세손에 따라 계산되었다(남자: 80.15, 여자: 75.68). 성별에 따라 점수를 비교했을 때, 남자 학생들의 점수가 왼손, 오른손 손 검사에서 모두 높은 점수를 얻었다(p<0.05).결론 : 본

Poly(oxypropylene-oxyethylene glycol) block copolymer(PBC) oil dispersant, which has low toxicity, high biodegradability, and an excellent dispersion efficiency to crude oils and weathered W/O emulsion was prepared by blending PBC, poly(oxyethylene) oleate, and sorbitan monooleate. The dispersing efficiency was measured by swirling flask method. The PBC oil dispersant had an excellent dispersing efficiency to weathered oil products formed as stable W/O emulsion, and the low toxicity, such as 4000 ppm to Oryzias Latipes(24 hr, TLM), Brine Shrimp Artemia(24 hr, TLM).

The purpose of this study was to assess the effect of visual block (eyes open or closed), mental task type, and participation in an exercise program on static balance in the elderly. The subjects were 34 elderly (>65 years old) residents of a social welfare institute in Gyeonggi-do. We measured the following variables. Berg balance scale, mini mental state examination, balance performance monitor (sway area, path, and maximal sway velocity), age, weight, height and whether the subject participated in an exercise program. Scores for the Berg balance scale and mini mental state examination were evaluated to assess static balance ability either alone (single task paradigm) or while performing a mental task (dual task paradigm). Static balance variables that were measured included sway area, path, and maximal sway velocity. Each test was repeated three times. Multiple regressions analysis was used to examine the effect of each variable on static balance ability. For the dual task paradigm, static balance was affected by whether the subject participated in an exercise program. The Berg balance scale score for subjects with their eyes open was affected by whether they participated in an exercise program, while this variable in addition to the height and weight of subjects were determining variables in subjects with their eyes closed. As a result, whether subjects participated in an exercise program affected their static balance irrespective of whether their eyes open or closed. Therefore, regular exercise is recommended for elderly people and further research is needed to examine the relationship between static and dynamic balance while performing mental tasks such as cognition and attention.

Pregnancy block by male pheromones in mice differs in incidence depending on the combination of strains. Female mice of BALB/cA strain mated with BALB/cA males show a 100% pregnancy block when exposed to males of inbred strain DDK shortly after copulation (Chung et al., Biol Reprod 1997). In the present study, BALB/cA females mated with the males of other strains (CBA/J, C3H/HeN, C57BL/6Cr, and IXBL) showed higher pregnancy rates (66.6-87.5%) even when they were exposed to DDK males. In the pharmacological induction of pregnancy block with dopamine agonist (Bromocriptine, 4mg/kg BW), BALB/cA females mated with BALB/cA males showed a 100% pregnancy block. In contrast, BALB/cA females mated with CBA/J, C3H/HeN, and C57BL/6Cr males showed higher pregnancy rates (40-70%). These results suggest that the better pregnancy rate of BALB/cA females mated with alien males may be due to the stronger viability of F 1 embryos. This interpretation was confirmed by an embryo transfer experiment in which a higher implantation rate was observed when BALB/cA embryos grown in BALB/cA females exposed to BALB/cA males were transferred into recipient BALB/cA females exposed to DDK males. These results suggest that the embryonic genotype or viability of the embryo is one factor contributing to the occurrence of pregnancy block by male pheromones in mice.

텍스타일 패턴 디자인에 대한 소비자의 감성을 반영하는 한 방법을 제시하기 위하여 블록 스트라이프 패턴 (block stripe pattern)에 대한 디자인 요소를 조사하였다. 자극물은 명도차(3가지), 배열(2가지), 폭(2가지), 간격(3가지)의 4가지 요소를 조작하여 구성되었다. 36가지 조합 중에서 사전 조사에서 독립적인 감성을 보이는 27개를 최종 자극물이 선정되었으며, 남녀 대학생 30명을 대상으로 감성평가를 실시하였다. 4가지 디자인 요소가 요인분석을 통해 도출된 12개의 감성차원에 미치는 영향을 측정하고, 물리량에 근거한 정량적 분석을 통해 각 자극물과 감성과의 관계를 파악하였다. 각 디자인 요소가 감성에 미치는 영향을 ANOVA 분석한 결과, 명도차, 간격, 폭, 배열의 순서로 의미있는 감성차이를 유발하였으며 명도차는 거의 모든 감성에서 감성차에 영향을 미치는 가장 설명력 높은 디자인 요소로 분석되었다. 디자인 요소 레벨에 따른 감성의 차이를 살펴보면, 폭이 좁을수록 '수수한', '깨끗한', '모던한', '심플한', '편한' 감성을, 간격이 좁을수록 '강렬한', '보수적인' 감성을, 명도차가 작을수록 '고급스러운', '모던한', '수수한', '심플한', '점잖은', 보수적인', '소프트한', '깨끗한', '편한' 감성을 나타내었다. 감성을 요소별 물리량으로 예측한 회귀모형을 도출한 결과, 12개의 감성 중 '보수적인', '캐주얼한', '모던한' 감성을 제외한 모든 감성에 대해 R²가 0.6 이상의 높은 적합도를 보였다. 이 결과를 토대로 소비자 감성이 반영된 2가지 디자인 프로토타입을 제시하였다.
