Since the 1970s, the average life expectancy of Koreans has been increasing. Our concerns are not simply about longevity, but also about disability-free life. lately, Sasang constitutional medicine has attracted public attention, especially with respect to the elderly. The purpose of this study was to investigate the food habits, nutrients intake, and disease distribution among the elderly, according to their Sasang constitutions. The results are as follow : The distribution of constitutions of the subjects were Tae-eum 48.8%, So-yang 27.4%, So-eum 22.6%, and So-yang + So-eum 1.2%. In both elderly men and women, body weight, percent ideal body weight, and diastolic pressure of the Tae-eum were significantly higher than those of other constitutions. In both men and women, the level of hemoglobin in the Tae-eum was significantly higher than those of other constitutions. The level of LDL-cholesterol was higher, and the level of HDL-cholesterol was lower in the So-eum elderly women. Food habits of the So-eum were the most irregular, and nutrients intake of the So-eum was lower than that of other constitutions in both elderly men and women. In elderly men, the incidence of hypertension was the highest in the Tae-eum, and the incidence of gastritis was the highest in both So-yang and So-eum. In elderly women, the incidence of fatty liver was the highest in the Tae-eum and So-yang, and gastritis and hypertension were the highest in the So-eum. In the elderly, obese and anemic persons were significantly more in the Tae-eum and the So-eum, respectively. The results of this study showed that there were significant differences of physical, characeristics, food, habits, and distributions of disease for the subjects according to each Sasang constitutions. Intake of nutrient was poor, regardless of Sasang constitutions, in both men and women.

To cope with automobile exhaust gas regulations, ISG (Idling Stop & Go) and charging control systems are applied to HEVs (Hybrid Electric Vehicle) for the purpose of improving fuel economy. These systems require quick charge/discharge performance at high current. To satisfy this characteristic, improvement of the positive electrode plate is studied to improve the charge/discharge process and performance of AGM(Absorbent Glass Mat) lead-acid batteries applied to ISG automotive systems. The bonding between grid and A.M (Active Material) can be improved by applying the Sand-Blasting method to provide roughness to the surface of the positive grid. When the Sand-Blasting method is applied with conditions of ball speed 1,000 rpm and conveyor speed 5 M/min, ideal bonding is achieved between grid and A.M. The positive plate of each condition is applied to the AGM LAB (Absorbent Glass Mat Lead Acid Battery); then, the performance and ISG life characteristics are tested by the vehicle battery test method. In CCA, which evaluates the starting performance at -18 ℃ and 30 ℃ with high current, the advanced AGM LAB improves about 25 %. At 0 ℃ CA (Charge Acceptance), the initial charging current of the advanced AGM LAB increases about 25 %. Improving the bonding between the grid and A.M. by roughening the grid surface improves the flow of current and lowers the resistance, which is considered to have a significant effect on the high current charging/discharging area. In a Standard of Battery Association of Japan (SBA) S0101 test, after 300 A discharge, the voltage of the advanced AGM LAB with the Sand-Blasting method grid was 0.059 V higher than that of untreated grid. As the cycle progresses, the gap widens to 0.13 V at the point of 10,800 cycles. As the bonding between grid and A.M. increases through the Sand Blasting method, the slope of the discharge voltage declines gradually as the cycle progresses, showing excellent battery life characteristics. It is believed that system will exhibit excellent characteristics in the vehicle environment of the ISG system, in which charge/discharge occurs over a short time.

This study was conducted to determine the eating habits of obese elementary school students residing in Iksan city, in June 2006 using 1167 participants(obese: 233, normal weight: 934). The results are summarized as follows. The average age was 12 years-old in both the obese and normal weight groups. The average BMI, ideal body weight and obesity index in the obese and normal weight groups were $24.8kg/m^2$, 39.8 kg, and 32.5% and $18.2kg/m^2$, 37.7 kg and -1.4%, respectively. Regarding the number of subject who acknowledged their physical build, the obese group was highest(88.9%) in stating obese or extremely obese, while the normal group was highest(71.5%) in stating they were normal weight. For the frequency of eating breakfast, the obese group the results were: "eating it everyday"(69.1%) and $"3{\sim}4\;times/week"$ (13.7%), while in the normal weight group, the highest response was "eating it everyday"(75%) and the lowest response was "never eat it"(4.1%). In terms of having breakfast with someone, there were slight differences for eating alone between the obese group(17.4%) and normal group(12.4%) and also between the obese group(19.6%) and normal group (39.6%) for eating with parents. There were considerable gaps in the association of eating habits with weight such as having irregular meals in the obese group(52.4%) and having regular meals in the normal group(61.1%). The frequency of having snacks was different by the rate of obesity, where 65.9% of the obese group, and 57.8% of the normal group had snacks more than once. There were significant differences in the practice of controlling intake with the obese group at 77.3% and the normal group at 36.3%. There were high numbers regarding eating more than average in stressful times for both the obese group(10.3%) and normal group(7.7%). The results of this study show the prevalence of obesity in Iksan, and proper nutrition education is currently needed. Moreover, the greater the level of obesity, the higher the frequency of skipping breakfast, eating alone, and eating irregular meals, and the more experience in attempting to control weight. To resolve the problems triggered by inappropriate food habits, proper food and eating methods to control weight should be included in nutrition education programs for elementary students.

After accepting the modernized western culture, we, the Koreans, had traditionally patriarchal valuation on the family life, which has been changed into modernize on in these days. Under these circumstances, we examined into family consciousness of workmen, office workers and student of universities in Pusan with questioning papers by inquiring their general views of family, marriage, family planning , and inheritance. The results obtained can be summarized as follows. 1. General views of family 1)Most of them prefer nuclear family to gross one in structure of family. In decision of family's affairs, the lower educated persons want an unilateral relationship, which means unconditional obdience to their parent's opinion. they are more concerned about the profit of the family than that of individual. on the other hand, they want 2-generations nuclear family system. 2) Concerning children's future affairs, they want compromising method. 2. Views of Marriage 1) Date with the other sex motivated their desire to improve social adaptation and social association. 17-19 year old students regard date as a preparatory stage of marriage. They consider it most desirable date to enjoy free conversation each other. They hope their date partners are high educated. 2) The conditions of mate selection are in order character, health, vitality in living, appearance and education. The less educated placed an emphasis on vitality in living. 3) They are not much interested in marital harmony. If parents are against their marriage an account of bad marital harmony, they will take into consideration about it. 4) They wish to keep purity before marriage, as possible. They want engagement period of 6 months. Any agreeable reasons shall compel them to break off their appointment. 5) they consider it ideal for mate's age to be 26-30 years old, and also think it affirmative to follow their parent's agreement in marriage. It is considerable that they put off their marriage only because they have lots of work to do before marriage. 6)Marriage declaration is to be made on the wedding day. It still exists that they don't want to marry when they are inth same surname and family tree. But it is clear that they don't regard it as the reason of breaking off the betrothal. 3. Family Planning 1) They are willing to agree to the campaign "just two is enough". They want a son and a daughter. Even though they have two daughters, they won's bear child to get son. 2) the lower educated persons are ignorant of the method of birth control. 4. Inheritance 1)Most of them say householder inheritance is to be kept up continuously. It is reasonable that anyone who can afford to perform religious service should bear it responsibility. 2)They don't want the difference in inheritance as the conscious to the conscious of the equality of the sexes spread widely into our society, but it is worthy of notice that some of them still don't mind unequal treatment. 3) When they have no child, the property inheritances are in order his wife and his parents. According to above mentions, we conclude like this: Their consciousness of marital harmony, marriage, family planning and inheritance shows definitely passive rationism in the transitional stage which is mixed with western individualism and traditional feudalism. On account of being lack of steady fast self-conscience, they can not make their positive reaction on anything. Finally, we should make every possible efforts to have our firm self-conscience through the re-education.

이 논문은 소설 『토지』의 주요 무대이자 작중인물들의 삶에 새겨진 원체험 공간인 평사리의 의미를 진단하고 <토지> 콘텐츠 플랫폼으로서의 평사리의 방향성을 제안한다. 소설 속 가상공간인 평사리는 원작의 배경지에서 출발하여 하동군의 대표 문화 공간으로 현재 자리매김하고 있다. 그런데 이 공간의 방문자들이 자기만의 장소성을 체험하기 위해서는 문화체험형 콘텐츠로 재탄생할 필요가 있다. 원작에서 평사리는 이상적 공동체이자, 수난과 개척이라는 한국 근대사의 축도로 존재한다. 그러므로 이러한 의미를 살려 유교문화, 여성의 노동문화, 무속문화를 보여주는 문화체험공간을 마련하여 방문자들의 체험을 이끌어내야 한다. 아울러, 평사리 재편의 동력이 된 변용작품들과 연계하여 앱을 개발하고, 증강현실을 이용한 교육과 체험 공간을 웹에 마련한다. 디지털과 현실의 이러한 교호작용은 원작이나 변용작품들의 의미를 사유하게 하는 동시에 방문자들이 저만의 장소성을 확보하는데 기여한다. 또한 이를 통해 평사리는 한국문화와 삶의 의미를 사유하는 문화체험 콘텐츠 플랫폼으로의 진화가 가능하다. 이 글은 '의미 있는 장소들의 지리'를 위한 평사리의 공간 기획 방향성을 제언한다는 점에 그 의미가 있다. 또한 문학 작품 원작의 상상 공간이 현실의 공간을 어떻게 재편해 왔는지를 보여줌과 동시에 문학작품의 미디어 콘텐츠화와 문화예술산업 지형 구축에도 시사점이 있다.

비어 람버트 법칙에 의하면 충분히 묽은 용액에서 주어진 파장에서 측정한 흡광도는 용질의 농도에 비례한다. 반대로 충분히 묽은 용액이란 측정한 흡광도 값이 용질의 농도에 비례관계를 가지는 범위에 있는 용액을 말하지만 실제 확신하기가 어렵다. 본 연구에서는 벼 잎에서 추출한 엽록소 80% 아세톤 용액을 사용하여, 측정한 흡광도 값의 신뢰도를 판단할 수 있는 기준으로서 엽록소 a/b 비례치의 사용 가능성을 4가지 다른 흡광분광분석기(Cary4E, UV-1650PC, Versamax, NanoDrop 100)을 사용하여 조사하였다: 우선 $0.2{\mu}g/ml$의 매우 저농도에서 $200{\mu}g/ml$까지의 다양하게 희석한 엽록소 용액을 사용하여, 645 nm와 663 nm에서 측정한 흡광도 값을 측정한 후, 흡광도 값과 엽록소 농도의 비례관계를 조사하였다. 그 결과, 이 비례관계로 판단한 측정치의 신뢰 범위에서 흡광도로부터 계산한 용액에서의 엽록소 농도와 이미 알고 있는 엽록소 농도 비교적 일치하였다. 그러나, 비례관계의 한계치 안에 있어 신뢰도가 인정된 일부 고농도와 저농도에서의 일부 값이 엽록소 a/b 비례치가 용액의 희석에 변화지 않을 것이라는 판단 기준에 있어 신뢰도가 떨어짐을 알 수 있었다. 그러므로, 본 연구결과는 엽록소 농도결정을 위하여 측정한 흡광도 값의 신뢰 여부는 대상 용액을 희석하여 측정한 흡광도의 비례관계로 본 비어-램버트 법칙의 기준 보다는 엽록소 a/b 비례치가 변하지 않는다는 기준으로 측정치의 신뢰도를 판단하는 것이 더 좋다는 것을 확인할 수 있었다.

This is a pilot study on rural women's psychological trap to define some obstacles to self directed learning. During few decades, according to major crop of each farm household has shifted from rice to other crops like as vegetables, fruits, horticultures, livestock, etc., women's role or labor sharing of women in farming has been also increased. Although women are important human resources, till now, there is no a research or an approach to rural woman on the view of individual human being. Therefore this study will contribute to understand woman's behavior or attitudes based on psychological description at each person's experiences. For this study, the data was collected from 23 women leaders who participated in a training course in 2005, through the scale of Jeffrey E. Young & Janet S. Klosko which was developed to improvement of one's repetitious behavior based on cognitive psychological care. It was categorized into 11types of psychological trap of one person, named as follows; (1) trap of being deserted by someone (2) trap of disbelief and being ill-treated (3) trap of weakness (4) trap of dependence (5) trap of emotional deprivation (6) trap of feelings of alienation among society (7) trap of deficiency (8) trap of anxiety to failure (9) trap of subordination (10) trap of the merciless standard by self-estimation (11) trap of the sense of privilege. From the data, the average age of subjects was 52.8years old, and the educational back of subjects was higher than general rural women. In both of the trap of weakness and the trap of the merciless standard by self-estimation, the ratio of over and 4 point score of 6 points was 71.4% and 76.2%. It means most of subjects have experienced fear of unexpected calamity(trap of weakness), and mental press hard for efforts to meet one's ideal standard(trap of the merciless standard by self-estimation). Especially the trap of the merciless standard by self-estimation may have relation with rural women's over burden from farming and local society activities.

A movie is a fiction made on a basis of an author's and a writer's imagination, but all sorts of properties mixed with each other and most realistically expresses the era which becomes the background of a movie and acts as a carrier that connects designers with consumers. Thus, this study was carried out to review how the fashion products that designer's intention and commercial value added are expressed in collections by comparing and analysing the costumes in the movie "The Great Gatsby" that described the life of America's upper-class in 1920s and the 04 S/S Y&Kei collection which were proceeding after getting inspiration from this movie. For this, literature materials were inspected in order to make a theoretical review on social and cultural background and costumes history background in 1920s and the photo materials on movie costume were collected and analysed using DVD video captures, as well as the photo materials on 04 S/S Y&Kei were collected and analyzed through the institute providing domestic fashion information. The following conclusion was deduced through this study. First, in 1920s which becomes the background of this study, the slim shape of Flapper which looks like a young and boy became an ideal figure condition and the straight silhouette with low waist line and the short skirt that rose to knee was popular. Second, as a result of analysing movie costume by classifying it in silhouette, colors, and materials, straight silhouette of low waistline with a near colored - tone seen in the pastel series, including white, beige, pink, and gray was mainly constituted and the metal colors like silver and gold were used. As a material, chiffon, satin, velvet, flower patterned prints, and beads were used, which represented luxurious life of women in the upper classes. Third, as a result of comparing and analysing, it turned out that there was a similarity. However, in dress collection for a heroine, some dissimilarity differentiated from a movie costumes was found out in that the dresses in collection expressed moderate beauty and modernism and elegant beauty at the same time by matching a variety of materials and using black color.

Three-dimensional porous scaffolds play an important role in tissue engineering strategies. They provide a void volume in which vascularization, new tissue formation, and remodeling can occur. Like any grafted materials, the ideal scaffold for bone tissue engineering should be biocompatible without causing an inflammatory response. It should also possess biodegradability, which provides a suitable three-dimensional environment for the cell function together with the capacity for gradual resorption and replacement by host bone tissue. Various scaffolds have already been developed for bone tissue engineering applications, including naturally derived materials, bioceramics, and synthetic polymers. The advantages of biodegradable synthetic polymers include the ability to tailor specific functions. The purpose of this study was to examine the osteogenic activity of periosteal-derived cells in a polydioxanone/pluronic F127 scaffold. Periosteal-derived cells were successfully differentiated into osteoblasts in the polydioxanone/pluronic F127 scaffold. ALP activity showed its peak level at 2 weeks of culture, followed by decreased activity during the culture period. Similar to biochemical data, the level of ALP mRNA in the periosteal-derived cells was also largely elevated at 2 weeks of culture. The level of osteocalcin mRNA was gradually increased during entire culture period. Calcium content was detactable at 1 week and increased in a time-dependent manner up to the entire duration of culture. Our results suggest that polydioxanone/pluronic F127 could be a suitable scaffold of periosteal-derived cells for bone tissue engineering.
