  • For the elucidation of the nutritional status of residences of apartments located in various areas in Seoul city, the food and nutrition survey was undertaken by the graduate students from Department of Food & Nutrition, Ewha Womans University in 1973. The socioeconomic stratification was mainly considered for the selection of sample apartments included in this study. Hangang Mansion, KIST, Munwhachon & Bukahyun apts were selected in this respect. A. Common living circumstances. Through the questionaries, author concluded nutritional concept on everyday food life as follows; 1. Higher income seems less effective in everyday food life on the nutritional view point than higher education does. 2. It needs to be urgently improved to be accustomed to use exact measuring concept of foods when they cook. 3. It needs to be improved to serve meals for individual portion at meal table, because the portion control at meal table will effect to national food policy. B. Nutrition Survey. Average daily calroie intake was the highest in Hangang Mansion and lowest in Bukahyun apt., in accordance with their economic living standard, but most of their calorie intakes were lower than the R.D.A. (3000ca1 for male, 2200 Cal for female). But the composition ratio of the total calorie intake was near to the ideal, carbohydrate 60%, protein 15%, fat 25%. Although there were differences in their economic living situations in urban area, most people ingested relatively good quality and large amounts of protein and fat. Vitamin A and Niacine intake exceeded the R.D.A., but the intake of Ca, Thiamine, Riboflavin, Ascorbic Acid were far less than that of R.D.A. C. food Intake. Amounts of total daily food intake were highest in Bukahyun apt. and lowest in Hangang Mansion. These showed adverse aspects to the total calorie intakes and their income levels. The ratio of cereals, $40%{\sim}50%$ of the total food intake, was higher than any other kinds of foods in all apartments. Among the other foods except cereals, there represented the highest level of meats in Hangang Mansion and KIST apt., while intake of Kimchies were highest in Munwhachon and Bukahyun apt. In the case of vegetables and fruits intake, the ratio of them in Hangang Mansion and KIST apt. were high, on the other hand the ratio of starchy roots appeared lowest in Hangang Mansion. For the main sources of protein, meats were ingested in Hangang Mansion and KIST apt., meats and fishery were used in Munwhachon apt., and beans were eaten highly in their meals in Bukahyun apt. These food contents and distributions showed the significant differences not only their economic classes but also regional characteristics.

  • Objectives: In the present study, three kinds of tissues cells (pulp, gingiva, and periodontal ligament) were investigated if those cells express MMP and TIMP when they were stimulated with neuropeptides (substance P, CGRP) or proinflammatory cytokine, TNF-$\alpha$. Materials and Methods: The cells cultured from human dental pulp (PF), gingiva (GF) and periodontal ligament were (PDLF) stimulated with Mock, SP, TNF-$\alpha$, and CGRP for 24 hrs and 48 hrs. for an RNase protection assay and Enzyme Linked Immunosorbent Assay. Cells (PF, GF and PDLF) seeded in 100 mm culture dish were stimulated with SP ($10^{-5}$, $10^{-8}\;M$) or only with medium (Mock stimulation) for 4hrs and for 24 hrs for RNase Protection Assay, and they were stimulated with CGRP ($10^{-5}\;M$) and TNF-$\alpha$(2 ng/mL) for 24 hrs and with various concentraion of TNF-$\alpha$(2, 10, and 100 ng/mL) for Rnase Protection Assay with a human MMP-1 probe set including MMP 1, 2, 8, 7, 8, 9, 12, and TIMP 2, 3. In addition, cells (PF, GF and PDLF) were stimulated with Mock and various concentraion of TNF-$\alpha$(2, 10, and 100 ng/mL) for 24 hrs and with TNF-$\alpha$(10 ng/mL) for 48 hrs, and the supernatents from the cells were collected for Enzyme Linked Immunosorbent Assay (ELISA) for MMP-1 and MMP-13. Results: The expression of MMPs in PF, GF, PDLF after stimulation with SP and CGRP were not changed compared with Mock stimulation for 4 hrs and 24 hrs. The expression of MMP-1, -12, -13 24 hrs after stimulation with TNF-$\alpha$ were upregulated, however the expression of TIMP-3 in PF, GF, PDLF after stimulation with TNF-$\alpha$ were downregulated. TNF-$\alpha$(2 ng/mL, 10 ng/mL, 100 ng/mL) increased MMP-1 and MMP-12 expression in PF dose dependently for 24 hrs. Conclusions: TNF-$\alpha$ in the area of inflammation may play an important role in regulating the remodeling of dentin, cementum, and alveolar bone.

  • This study aimed at empirically identifying how the cultural phenomena of localisation and attachment are implemented through Mohyeonjeong and Supodae at Gajo-myeon, Geochang-gun, Gyeongnam. 'Daehakdong', the name of the place where the Mohyeon-jeong and Supodae is located, has a meaning of the place where Geong-Pil Kim(金宏弼) the Hanhwondang(寒暄堂), one of the 5 eastern sages, and Yeo-Chang Jeong(鄭汝昌) the Ildu tought Neo-Confucianism. In addition, in case of Mt. Odo(1,134m) embracing the garden, the meaning of Odo is the five virtues in Confucianism, so we can see that Confucianism was strong in that area. The meaning of 'Mohyeon(慕賢)', "missing and thinking of sages", reflects the emotion of attachment to the place where people pay a tribute to the memory of Seon-Saeng Yang the Hwondu, one of the 5 eastern sages and the creator of Neo-Confucianism in Kyeongnam, and Suk-Ryang Choi(崔淑梁) the ancestors Pyeongchon. In addition, Odojae(吾道齋), Kijeok monument to pay a tribute to the memory of Pyeongchon, the persimmon tree symbolizing Hanhwondang, and Jidongam(志同巖) standing in front of Mohyeon pavillion represent the united wills of the above 3 people to show their Dohak(道學) spirit by practicing it, and also a reiterated expression of attachment to the place. 'Hwonduyangseonsaeng janggujiso' and 'Pyeongchonchoigong ganghakjiso(坪村崔公講學地所)' engraved on the rock of Myeongso Supodae where they gave a lecture of Neo-Confucianism to local Confucianists for many years and enjoyed nature make us to identify the intrinsic meaning of the location that was inherited in the memory of people. Along with this, most of the content of poetry, restoration records, and Sangryang articles are filled with the content reminding of the historical meaning and origin of Mohyeon-jeong and Supodae, so we can see from this that the place had the spatial meaning of Jangsujiso(藏修之所), 'the place of lecturing and communicating' and respecting ancient sages. This spatial tradition is the result of positive attachment to the place, and Mohyeon-jeong and Supodae is the place where the attachment to the place was made spontaneously througth the localisation. To sum it up, Mohyeon-jeong and Supodae was the place of attachment where one paid a tribute to the memory of ancient sages, and Mohyeonjeong and Supodae rocks were the representative examples of the localisation to show the meaning of the place by implication. Studying the process of attachment and localisation of the place does not only enable us to infer the genuine form of the traditional memorial space and park, but also to reproduce the place with the modern concept.

  • The purpose of this study is to estimate an optimum formula of rainfall intensity on basis of the characteristics for short period of rainfall duration in Kyungpook province for the design of urban sewerage and small basin drain system. Results studied are as follows; 1. The optimum method for Taegu and Pohang, Iwai's and Gumbel-Chow's method are recommended respectively. 2. The opotimum type of rainfall intensity for these area, $I=\frac{a}{\sqrt{t}+b}$ (Japanese type), is confirmed with 2.52~4.17 and 1.86~4.54 as a standard deviation for Taegu and Pohang respectively. The optimum formula of rainfall intensity are as follows. Taegu : T : 200 year - $I=\frac{824}{\sqrt{t}+1.5414}$ T : 100 year - $I=\frac{751}{\sqrt{t}+1.4902}$ T : 50 year - $I=\frac{678}{\sqrt{t}+1.4437}$ T : 30 year - $I=\frac{623}{\sqrt{t}+1.4017}$ T : 20 year - $I=\frac{580}{\sqrt{t}+1.3721}$ T : 10 year - $I=\frac{502}{\sqrt{t}+1.3145}$ T : 5 year - $I=\frac{418}{\sqrt{t}+1.2515}$ Pohang : T : 200 year - $I=\frac{468}{\sqrt{t}+1.1468}$ T : 100 year - $I=\frac{429}{\sqrt{t}+1.1605}$ T : 50 year - $I=\frac{391}{\sqrt{t}+1.1852}$ T : 30 year - $I=\frac{362}{\sqrt{t}+1.2033}$ T : 20 year - $I=\frac{339}{\sqrt{t}+1.2229}$ T : 10 year - $I=\frac{299}{\sqrt{t}+1.2578}$ T : 5 year - $I=\frac{257}{\sqrt{t}+1.3026}$ 3. Significant I.D.F. curves derived should be applied to estimate a suitable rainfall intensity and rainfall duration.

  • Mt. Kumjeong is located in south-eastern part of the Korean Peninsular($129^{\circ}$01' to $129^{\circ}$05' E, $35^{\circ}$03' to $35^{\circ}$17' N) and the altitude of the summit is 802 meter. In order to find out the vegetation units which made it possible to classify subtropical forest and south-temperate forest, Mt. Kumjeong (which is located in a border of between subtropical forest and south-temperate forest) was selected as a study area. The primary result of actual vegetation analysis in Mt. Kumjeong based upon the vegetation community analysis methods by the ZM-school, and the relationships between vegetation community and two parameters(altitude, topography) analyzed by using coincidence analysis method were summarized as followings. 1. Based upon analytic methods of the vegetation community by the ZM-schools, the primary analytic result of the analysis of vegetation community in Mt. Kumjeong was divided into 10 communities, 9 groups, 2 subgroups. 2. Eurya japonica group of Pinus densiflora community out of 16 vegetation units was thought as a indicator vegetation group which made it possible to border subtropical forest and south-temperate forest. 3. Natural regeneration of Stewartia koreana group was thought to be difficult because seedling and sapling was rarely showed, 4. In relationship between vegetation units and altitude, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community, Pinus thunbergii community mainly distributed below altitude 500 meter, and Quercus mongolica community, Typical group of Pinus densiflora community, Quercus dentata community, Carpinus coreana community, Quercus acutissima community mainly distributed above altitude 500 meter. 5. In relationship between vegetation units and topography, Carpinus tschonoskii community, Quercus variabilis community, Quercus serrata community, Wisteria floribunda community,. Eurya japonica group of Pinus densiflora community distributed below middle slope, Quercus mongolica community, Typical group of Pinus densifiora community, Quercus dentata community, Carpinus coreana community, Pinus thunbergii community Quercus acutissima communily clistributed above midclle slope.

  • The internet has dramatically changed a way of business management and competition in the business environment. Especially, it stimulated not only to evolve online floral distribution service but also to change a phase of competition among floral retail stores in industry. And that also led to keen competition among IT service providers as well. This study is to examine how floral retail stores have been evolved and competed with the radical situation of the floral distribution industry through IT service in the aspect of business and information technology. In addition, the Typhoon Positioning Strategy(TPS), a strategy for the IT service positioning, is introduced from IT service provider's perspective. For IT service providers to create high business value and continuous service providing, IT service should be positioned on the customers' "core business" and developed to the level of "solution." The Typhoon Positioning Strategy(TPS) is a strategy for the IT service positioning, indicating that IT service should be positioned according to a Business Process-Service model with the consideration of business development direction, IT service trend, and user's IT capability. That is, IT service providers should find out customers' "core business" area first to provide a right IT service to the company, and the IT service provided should meet to the level of business solution. The capability of the IT solution users is also an important factor to be considered for the advanced IT service. There are four principles of the Typhoon Positioning Strategy(TPS). Principle 1) IT service provided should be an IT solution Map suitable for customer business processes. Principle 2) IT service provided should be able to support customer core business. Principle 3) IT service provided should be a business solution. Principle. 4) IT service provided should be applied differently according to the level of customer's IT capability.

  • To assess the food intake and diet quality of middle school students who live in Kangneung area, a dietary survey using 3-day food record was conducted with 226 subjects. Seventy five percent of total food intake was in the form of plant foods and the rest in the form of animal food. Diet qualify was assessed by food group pattern, dietary diversity score (DDS), and dietary variety score (DVS). When counting the major food groups consumed, 53% of subjects had a DDS of 3 and 35% of subjects had a DDS of 4. When investigating the consumption pattern of the major five food groups, only 10.2% of subjects consumed foods from all five groups. The groups most frequently missed were dairy products (73.0%) and fruits (71.7%). On average, subjects habitually consumed 22.6 different foods daily, with the mean score of diet variety for males (22.1) being significantly lower than for females (22.9). Correlation coefficients between nutrient adequacy ratio (NAR) and DVS ranged from r=0.40 for vitamin B$_1$to r=0.61 for phosphorus. NAR also improved as the number of foods or food groups consumed increased (p<0.001). Associations between the NAR and high level of DVS was more positive than those between the NAR with DDS. When assessing the dietary quality of subjects using DDS and DVS, many people appeared not to have a desirable food intake. Therefore, to lead them to have nutritionally balanced diet, educating students and their parents on nutrients and suggesting guidelines for a desirable diet is considered to be essential so that they can intake from all of major food groups and have various foods in their diet.

  • The research was carried out to investigate the related phenomena, the latent structures and synthetical characteristics in various growth factors of Phyllostachys bambusoides Sieb. et Zucc. growing at Damyang gun, Chollanamdo, using multivariate analysis. 1. By synthetical characteristics in canonical correlation between height-growth factor group and diameter-growth factor group, the former was determined by the culm height ($x_1$), and the latter by the. diameter of the largest internode($x_7$). And for those between quantitative growth factor group and qualitative growth factor group, the former was determined by the surface area($x_{10}$), and the latter by the diameter of the largest internode ($x_7$). 2. The ten growth factors of bamboo culm were simplified by two principal components on the basis of accumulated proportion aimed at 90%. The first principal component($Z_1$) as a "size factor" showed high correlation with growth factors except eye-height diameter($x_5$). The second principal component($Z_2$) as a "shape factor" showed high correlation only with $x_5$. 3. The bamboo culm, and the latent phenomenon between their growth factors could be determined by two common factors showing high communality(94.16%). The ten growth factors can be grouped into two attribute factors: quantity and quality. 4. The bamboo culms can be classified into five types: total, volume, shape-quality, inferior and middle.

  • Eighty percent of Gangweon-Do area is mountain forests, and of all others this province has the largest number of "Hwajeon-farmers" (who illegally reclaim the mountain forests to do farming as long as the soil is fertile enough to yield profit, but when it fails, move to other places to repeat the same forest burning, causing tremendous forest damages). In 1965 a 7-year plan was mapped out to exterminate this gipsy-farmers only to be suspended in 1969 to give way to the stronger urge from the national security view-point to first displace those isolated farmers set in deep mountains. In the meantime an increased number of the Hwajeon-farmers burned the forests, working new havoc. To cope with the situation, the provincial government lounched another 4-year plan in 1973 and has been enforcing the resettlement policy with renewed enthusiasm. Whether the plan will succeed depends entirely on the authority involved can solve the problems listed below with regard to the Hwajeon-farmers who are to lose their only means of survival and move down to the low-lands: 1) Their living must be taken care of until they can have definite means of self-supporting. 2) They must be provided with the opportunity to work in connection with the government-sponsored labor programs. 3) Not only the public organizations but also the private firms must give them the priority to get work. 4) The rural revitalization movement must expand the self-help reconstruction projects to absorb their labor powers. 5) The Hwajeon-farmers themselves must have the spirit of self-help and self-supporting. 6) All the citizens in the province must receive and protect them with brethren love. 7) The function of the watch-posts against the Hwajeon-farmers must be strengthened again.

  • The present study was carried out in order to investigate seasonal variation in tannin, sugar and protein contents of persimmon fruits, Five varieties of Diospyros kaki Thunberg, i. e, Buyoo, Wolha, Kapjubackmok, Pyungmuhek, Heuksi, and Goyom (Diospyros Lotus Linne var. typica Makino) growing in Jeonbug area were used as the experimental material. The result are summarized as follow; 1. Maximum tannin contents were 4% in Buyoo, 5.46% in Wolha, 5.4l% in Kapjubackmok, 5.1 % in Pyungmuhek, 9.2% in Heuksi, and 26.1% in Goyom, respectively. Therefore, Heuksi and Goyom were considered to be the most useful as tannin material. 2. The most suitable season for tannin extraction was thought to be July with most varieties but it was August with Goyom. 3. The total sugar contents seemed to increse linearly. Linear regressions are as follows. Buyoo ; $\hat{Y}=0.2394x+3.861$ Wolha ; $\hat{Y}=0.3093x-1.148$ Kapjubackmok ; $\hat{Y}=0.3173x-1.3708$ Pyungmuhek ; $\hat{Y}=0.2796x+0.982$ Heuksi ; $\hat{Y}=0.3233x-3.242$ Goyom ; $\hat{Y}=0.1555x-4.780$ 4. Average crude protein contents of fruits through the year were 5.32% in Buyoo, 4.97% in Kapjubackmok, 4.49% in Goyom, 4.11% in Wolha, 4.02% in Heuksi, and 3.6% in Pyungmuhek, respectively. 5. The crude protein contents tend to decrease gradually after fruit setting.
