This study was conducted to investigate the relationship between alcohol consumption, physical activity and breast cancer risk in Korean women. Newly histologically identified cases (N = 108) were selected at Hanyang and Soonchunhyang University Hospitals in Seoul, from January 1998 to August 1999. Hospital-based controls (n = 121) were the patients who visited at the same hospital in the department of plastic surgery, general surgery and opthalmology. Subjects were asked informations on demographic, reproductive, and history of breast feeding as well as physical activity, exercise habit, alcohol consumption by individual interview. Odds ratio (OR) and 95% Confidence Intervals (CI) were calculated by using unconditional logistic regression after adjusted for confounding factors. Among postmenopausal women, the risk of breast cancer increased with increasing alcohol drinking: relative risk for the highest group ( $\geq$ 150 g per week) compared with the lowest group (never drinking) was 2.05 (CI=1.74-3.79). Association of exercise and high physical activity for breast cancer appeared to be limited to women with high physical index among postmenopausal women. We observed decreasing risk of breast cancer with increasing physical activity index among postmenopausal women (OR=0.49,95% CI=0.56-0.92). Results of this study support a protective effects of physical activity during adulthood for breast cancer. (Korean J Nutrition 36(1): 40-48, 2003)

The cement industry is one of the rapidly growing industry in Ethiopia. The average per capita cement consumption of the country has increased from 39kg to 62kg. However, this is still way below than the global average per capita consumption of 500kg. The Ethiopian government is planning to expand its cement industry by upgrading the current cement plants and also opening of new cement plants in order to meet the future demand of the country. Currently, the number of cement plants in Ethiopia has reached to 20. By the year 2025, per capita cement consumption is expected to increase to 179kg. Recently, Ethiopia has become one of Africa's largest market for the cement industry. In addition, Ethiopia has become the major exporter of cement in the Sub-Saharan African region. The Ethiopian cement industry is highly dependent on the use of imported energy sources for its production. This situation has a significant amount of impact on the high production costs of the industry. This paper will try to review the history, production, available resources, the technologies and energy use of the Ethiopian cement industry.

The various kinds of consumption belong to a general category and at the same time the expression of most basic aspiration in the human life. Since the ancient times, the consuming activities have lasted with the other basic activities and the consuming space conducting consumption has developed as physical devices along with the human history. Those companies that have been given attention and getting favorable impression currently being selected by the consumers are now concentrated on the storytelling marketing. The storytelling marketing is that the emotion-oriented marketing activities give consumers the opportunities to enjoy the product contained stories to put the stories to marketing activities. It approaches to consumer with human story emotionally rather than rationally and heart rather than mind. Recently, the architecture has become artistic either it was linked and contacted media or part of marketing. We think that the story telling marketing is the eternal triangle among art, architecture and marketing that is a propensity or movement to interior at this time. I found out that the storytelling marketing methodology is able to touch the consumer's heart and stimulate consumption aspiration that makes new circumstances and experience expressing space. And for that, effective marketing methodology is to give the consumers a more exciting and enjoyable motivation in accord with the modern society to give companies positive image to customers and accordingly for the companies to gain profits. The story telling space that is filled with ideas which produce new circumstance and experience using the established narrative and theme will be required continuously and able to develop in the future.

The purpose of the present study was to investigate the relationship between nutrient status, and bone mineral state which influenced by aging process. The subjects were 196 people over 65 years old(male 72, female124). The present dietary intake was estimated by the 24-hr, recall method, and individual dietary history concerning consumption of meat, fish and dairy products was obtained by questionaires. The syndrome of senility including seniliy was evaluated according to "Cornell Medical Index". The five subjects who showed 'Good' grade in bone senility, and five subjects who showed 'Risk' and 'Danger' grade were selected and their spine and femur bone density was measured by "Dual Photon Absorptiometry". The bone density measurement showed that the subjects with 'Good' grade in bone senility had bone density above that of normal person, and their nutrient status were satisfactory, whereas the subjects with 'Risk' and 'Danger' grade in bone senility had severe osteoporotic pattern, and their nutrient status were very poor. The food consumption score showed that the subject with higher intake of meat rather than milk had good grade in bone senility (p<0.05). Therefore, past meats consumption can be considered to be a significant factor in the present bone status. The nutrient intakes appeared to be significant factors in bone status in male, whereas there was little effect of nutrients intakes in female. Therefore, the risk of osteoporosis can increase as syndrome of bone senility and nutrient intakes were worse, and its is possible to evaluate bone status and predict osteoporosis simply from informations concerning syndrome of bone senility and nutrient intakes in old population over 65.

The chicken has been growing in Korea for more than a thousand years according to the history book and commercially rising for broiler meat only since 1960's. As income increased mainly due to improved economy, it changes the habit of eating especially chicken meat. The structure changes into a coordinated production and marketing system which forced the prevailed small and independent producers to become a contract farmer under the vertically controlled practices. This coordinated structure began in 1970's and evolved continually to occupy around 90 percent of the market in 2010 with some ten (10) private brands being advertising. The industrial organizations have also conducted the generic promotion by a farmer's check-off program. Over the past 20 years, chicken import steadily increased to meet about 25 percent of the domestic market while the export showed negligible growth. As a whole, the structure change and international trade devoted to increased chicken consumption from 2 kg with the independent operation to 11 kg currently under the coordinated system and import. It is predicted that chicken consumption will grow in years to come and the import will also increase in addition to local productions, considering the free trade agreement that has already been in practice with EU and US to open the market eventually from all sources of supply worldwide.

The location and human activity are usually used as one of the important parameters to monitor the health status in healthcare devices. However, nearly all existing location and monitoring systems have the limitation of short-range communication and high power consumption. In this paper, we propose a new mechanism to collect and transmit monitoring information based on LoRa technology. The monitoring device with sensors can collect the real-time activity and location information and transmit them to the cloud server through LoRa gateway. The user can check all his history and current information through the specific designed mobile applications. Experiment was carried out to verify the communication, power consumption and monitoring performance of the entire system. Experimental results demonstrate that this system can collect monitoring and activity information accurately and provide the long rang coverage with low power consumption.

현재 수치지도는 그 이력관리의 방법이 모호해 파일기반으로 영역단위 혹은 도엽단위로 관리되고 있다. 이는 변화되지 않은 지역을 중복적으로 관리하여 비용의 소모가 클 뿐 아니라 수치지도의 시간적, 공간적 관리방법이 제시되지 못하고 있다. 또한 수치지도를 파일기반으로 관리하기 때문에 관리의 보안성의 보장을 받지 못하며 관리의 체계화가 이루어지지 않는다. 따라서 본 연구에서는 수치지도의 각 객체별 이력관리를 위해 객체단위에 UFID를 부여 후 객체의 갱신이 이루어질 때마다 객체단위로써 이력관리 할 수 있는 방안을 연구하고자 한다.

The sea urchin, Mesocentrotus nudus, is widely distributed in North West Pacific regions. It has a substantial impact on macroalgal communities as a generalist herbivore. This study examined various aspects of its feeding ecology, including algal preference, foraging behaviors, and possible effects of past feeding history on its algal preference. We used six common algal species (Ulva australis, Undaria pinnatifida, Sargassum confusum, Dictyopteris divaricata, Grateloupia elliptica, and Grateloupia angusta) from the east coast of Korea as food choice in a series of indoor aquarium experiments. The first choice of starved M. nudus was exclusively U. pinnatifida, followed by G. elliptica and S. confusum. Unlike large urchins, small urchins equally preferred U. pinnatifida and G. elliptica. On the other hand, Undaria-fed urchins preferred to feed only G. elliptica, although its preference slightly differed over time. We then grouped sea urchins into three categories (starved, Undaria-fed, mixed species-fed) to observe 12-days feeding preference as well as early foraging movements. Foraging behaviors of the three groups were distinctively different, although they could not completely reflect the actual consumption. For example, U. australis was highly attractive, but rarely eaten. Undaria-fed urchins seemed to stay with only S. confusum and U. australis. This study demonstrates that M. nudus shows high flexibility in food preference depending on past feeding history and body size. Its foraging behaviors are also affected by past feeding conditions, exhibiting active chemoreceptive movements.

Background: Gallbladder cancer (GBC) is a rare but highly invasive malignancy characterized by poor survival. In a national cancer survey, the age-standardized incidence rate of GBC was highest in Jeju Island among the 15 provinces in South Korea. The aim of this descriptive epidemiological study was to suggest the modifiable risk factors for this rare malignant disease in Jeju Island by performing an age-sex-matched case-control study. Materials and Methods: The case group included patients diagnosed with GBC at the Department of Internal Medicine of Cheju Halla General Hospital, Jeju, South Korea, within the 5-year study period. The control group consisted of age-sex-matched subjects selected from among the participants of the health promotion center at the same institute and in the same period. We compared 78 case-control pairs in terms of clinical variables such as histories of hypertension, diabetes, vascular occlusive disorders, alcohol and smoking consumption, obesity, and combined polypoid lesions of the gallbladder (PLG) or gallstone diseases (GSDs). Results: Among the relevant risk factors, alcohol consumption, parity ${\geq}2$, PLG, and GSDs were significant risk factors in the univariate analysis. PLG (p < 0.01; OR, 51.1; 95% confidence interval [CI], 2.98-875.3) and GSD (p < 0.01; OR, 54.9; 95% CI, 3.00-1001.8) were associated risk factors of GBC in the multivariate analysis with the conditional logistic regression model. However, we failed to find any correlation between obesity and GBC. We also found a negative correlation between alcohol consumption history and GBC in the multivariate analysis (p < 0.01; OR, 0.06; 95% CI, 0.01-0.31). Conclusions: These results suggest that combined PLG and GSDs are strongly associated with the GBC in Jeju Island and mild to moderate alcohol consumption may negatively correlate with GBC risk.
