Generally the dynamic characteristics of stone wall structures depend on several factors such as contact, the type of interlocking bonding stones, and the filling materials. This paper describes a non-destructive technique for diagnosis of historic masonry stone structures using the measurement of natural frequency technique. For this purpose, the castle wall of Nag-An Folk Town located in Sunchon, Korea was selected as a model. The Nag-An Town Castle is one of the well maintained historical remains constructed in the Chosun Kingdom of Korea. The construction started in 1397 A.D and was finished in 1626 A.D. The non-mortar castle wall is 1470m long and the average height is 4m with a width of 3 4m. The exterior of the wall is bonded with 1 2 m rectangular rough-faced stone and the inside of the wall is filled with gravel. The traditional village still remains inside the Nag-An Town Castle, and they have a regional food festival every October. Transverse vibrations were measured at 8 points around the castle. The measured natural frequency of the first mode was 26Hz 41Hz, and the shear modulus of filling material was 2.142 x $10^3$ ~ 8.915 x $10^3$kgf/$cm^2$ . With these results, it may be assumed that the filling material is gravel or a sand-gravel mixture. It is expected that the information provided by this paper will be useful for addressing the maintenance problems of the old castle walls.

Landscape elements of historical and cultural value and elements that have negative impact on landscape due to reckless development teem in rural area. Due to this, local government has established a visual landscape plan. The purpose of this study is to analyze the process and content of domestic rural landscape planning process and to suggest improvements for it. For that, this study measure guideline of Ministry of Agriculture, Food and Rural Affairs against guideline of Ministry of Land, Infrastructure and Transport. To analyze the landscape planning guideline of australia which is similar to domestic rural landscape planning process, and to compare both guidelines. The results of this study are as follow. The stage of landscape resource survey and assessment progressed systematically, but it was not practical because for the lack of survey and assessment method. Therefore, it should be suggested for the survey and assessment technique. The rural landscape plan, established in master planning stage, do not necessarily reflect local government's landscape management on the ground of abstract technic of landscape management. For this sake, to develop evaluation method for development of landscape element seems necessary.

Cameroon, with her numerous resources, still depends on foreign aid while the rate of poverty remains high. Thus, even though historical evidence gives impetus to the impasse over role of developmental aid, from the top down approach through to development as a springboard raising states from the doldrums of poverty, it is still very difficult to draw a substantial relationship between developmental aid and poverty reduction. Against this backdrop of controversy, I find it apt to put Cameroon on a balance scale. Therefore, the purpose of this research is to critically assess the implications of developmental aid on poverty reduction and agro-rural development in Cameroon, using the RUMPI Area Development Project in the South West region of Cameroon as a case study. The study will situate and contextualize the top-down and bottom-up approaches to development within the basis of a Cameroonian perspective, using the Sachs-Easterly debate. The RUMPI Project was introduced with the objective of improving agriculture and empowering the rural woman; thereby fighting poverty within the South West region of Cameroon. Despite its criticism of the barriers to development created by corruption, political pressure and limited use of local and grass-root partnerships, the study, in assessing these failures also tries to outline vital ways in which the project can be improved upon.

The main purpose of milk heat-treatment is to improve milk safety for consumer by destroying foodborne pathogens. Secondly, heat-treatment of milk is to increase maintaining milk quality by inactivating spoilage microorganisms and enzymes. Pasteurization is defined by the International Dairy Federation (IDF, 1986) as a process applied with the aim of avoiding public health hazards arising from pathogens associated with milk, by heat treatment which is consistent with minimal chemical, physical and organoleptic changes in the product. Milk pasteurization were adjusted to $63{\sim}65^{\circ}C$ for 30 minutes (Low temperature long time, LTLT) or $72{\sim}75^{\circ}C$ for 15 seconds (High temperature short time, HTST) to inactivate the pathogens such as Mycobacterium bovis, the organism responsible for tuberculosis. Ultra-high temperature processing (UHT) sterilizes food by heating it above $135^{\circ}C$ ($275^{\circ}F$) - the temperature required to destroy the all microorganisms and spores in milk - for few seconds. The first LTLT system (batch pasteurization) was introduced in Germany in 1895 and in the USA in 1907. Then, HTST continuous processes were developed between 1920 and 1927. UHT milk was first developed in the 1960s and became generally available for consumption in the 1970s. At present, UHT is most commonly used in milk production.

The studies on nutrition counseling and screening have been based on stand-alone program. This study introduces the nutrition counseling and screening management system. This system offers convenient user interface and the synthetic results of counseling and screening with various utilities, The system for nutrition counseling and screening consists of the general information of clients, the anthropometry data, the calculation of obesity and body mass index, the state of eating habits, the computation of calorie expenditure, the clinical symptoms, the convenient method for analysis of calorie and nutrients, nutrition prescription and alcoholism screening tests. Having interoperability, these functions preserve the information of clients and manage the historical data. The system inserts, stores and generates the synthetic information of clients, so it is able to provide suitable and efficient counseling to clients. The proposed system gathers various information of clients. With accumulated client data, it does the nutrition education, screening and counseling simultaneously. Managing clients' information connected to database, it can provide systematic and formal information. It is possible for the system to retrieve information and counsel in real time. It is expected that the nutrition counseling management system can improve the national health with animated nutrition counseling. (J Community Nutrition 7(4) : $220\∼229$, 2005)

Purpose: This review describes the historical changes in nutrition philosophy from a reductionist to a holistic approach during the $20^{th}$ century. Also, the role and efficient use of a holistic approach to precision nutrition are discussed. Results: Over the past century, significant progress has been made in human nutrition research, unraveling fundamental mechanisms of single nutrients on single targets or pathways. This kind of a reductionist approach has helped to save populations from nutrient deficiency diseases and improve associated health outcomes in large parts of the world. However, a new set of nutrition problems, like obesity and diet-related chronic diseases, are growing each year worldwide, increasing the financial burden on the health care system. A linear cause-effect association between single nutrients and a single physiologic effect, is insufficient to solve the complex nutrition-health relationships. Research that involves a more holistic rather than reductionist approach is needed to tackle a new set of nutrition problems. Recent advances in technology, informatics, and statistical methods are enabling an understanding of the diversity of individuals and the complex interactions between foods and human bodies, leading to the concept of "precision nutrition." Conclusion: The emerging goal of precision nutrition is to provide tailored dietary advice for maintaining health and preventing obesity and diet-related chronic diseases. The parts are already being installed. To grab the complexity, reductionism and holism must be used interdependently.

The peasant societies of East Asia had been challenged by capitalist plantation since colonization and by socialist collectivization since decolonization. The former was decisively weakened due to the crisis of the capitalist system in the 1930s and the collapse of the colonial order in the 1940s; The latter was thoroughly discredited due to the reform of the socialist system in the 1980s and the end of the Cold War in the 1990s. The failure of the two epochal challenges demonstrates the historical sustainability of peasant societies in East Asia. Their survival represents the universality of Northeast and Southeast Asia, which can be ascribed to the ecological environment and production process of wet-rice agriculture for their common staple food. In spite of their diverse differences, indeed, peasant societies in colonial East Asia shared profound similarities in their basic motivations (morality-rationality), central tendencies (involution - polarization), structural outcomes (dualism - pluralism), and future prospects (survival-extinction).

In the 7th century, Prince Shoudoku built the Horyu temple at Nara, when Buddhist culture in Japan had highly prospered after Buddhism were transmitted to Japan from Korea. At the same time, the three ancient country of Silla, Koguryo, and Baekjae had generally effected on Japanese culture and life as well as Buddhist events, religious services and sacrificial offerings in form. And even now there are kept above one thousand of tablewares which was used at the age and was made of wood and alloy manufactures from Han peninsular in Seisoin at Nara. Through these historical backgrounds, it could be presumed that the religious services and the sacrificial offerings for Prince Shodoku for above 1300 years help us to study and estimate the ancient dietary culture of Korean and Japanese. There are several points of similarities which are remained and maintained in Han Peninsular. 1. They used high filling method of the secrificial offerings and high receptacles in the religious service. 2. The cakes were mainly made of nonglutinous rice tharr glutinous rice 3. They decorated the pheonix instead of flowers and the other kinds of birds in Korea. 4. Kakiage of fried confectionary was founded in many kinds of them at present.

Chemical engineering (ChE) was conceived at the close of the 19th century as a new discipline which was designed to support then the newly-emerging industries, oil and petrochemical, by supplying the competent engineers equipped with the pertinent engineering fundamentals and skills. It helped the said industries meet the various demands and ramifications of the new pattern of the human civilization spurred by the advent of automobile transportation at the turn of the 20th century. Now ChE once again is ready to fulfill its societal responsibility as probably the most important discipline and profession in sustaining the $21^{st}$ century human civilization providing the needed engineers (ChErs) and technologies. In this study, it is attempted to analyze the role of ChE and ChErs in this context, focusing on the macroeconomic connections embedded in the discipline that allow us to envision the big pictures of the 21st century civilization where the wellbeing of the mankind invariably hinges on five essential industries, i.e., medical, pharmaceutical, energy, environment and materials. It can be argued that ChE is the only discipline that can encompass simultaneously all those five industries indispensable to sustain the 21 st century human civilization that can be termed the era of "enjoy-healthy-living-longer". It is also believed that the historical mission ChE and ChErs are supposed to fulfill now is even bigger than that they took on a hundred years ago and subsequently accomplished with remarkable success in food, clothing, shelter and entertainment industries introducing various technological innovations. The macroeconomic viewpoints are called upon in this study as were in the 2006 article (Hyun, 2006) but focusing on ChE and ChErs this time to view the connections embedded in ChE as the essential components in understanding the historical nature of the role and responsibility of ChE and ChErs. The new paradigm for ChE is also pondered over together with the frequently-cited technology concepts such as IT, BT, NT, ET and ST which are regarded intimately germane to the characteristics and perspectives of the $21^{st}$ century civilization.

Ginseng has been recognized as a lifespan extending medicine which has been regarded as one of the medicines classified as top medicines, as the Boncho (medical herbs) study which is influenced by the idea of guidance's costume and food concept mainly in China is gaining its bona fide form. As the demand for ginseng has been expanded to other levels, the demand for ginseng has been increasing. Ginseng from the nature reached its supply chain limit due to its extinction and difficulty of picking, so it translated into ginseng cultivation of economy rather than harvesting in nature. After the start of ginseng cultivation, the ginseng cultivation was further enhanced by the rapid development of processing methods such as white-ginseng and red-ginseng, and the surge of consumption due to the traditional belief in ginseng drug efficacy and support of scientific research. In the Joseon Dynasty, the name Gasam (cultivated ginseng) had been created as ginseng was cultivated on farmland after the stage of SanYang (wild cultivated ginseng), the purpose of the new name Gasam is to differentiate from natural ginseng, and natural ginseng lost its firm position as the genuine ginseng as the Gasam replaced the genuine ginseng, and the natural ginseng got a new name of SanSam (wild ginseng). Because the real ginseng substance concept dissipated, and as Gasam is being called ginseng, the name Gasam was also disappeared. As a result, it was possible to grow large quantities according to the arrival of the Gasam era, and it was possible to supply the demand for ginseng, and it could become one agricultural industry. In this ginseng cultivation, in Japan where ginseng did not grow naturally, it was difficult to obtain ginseng from Joseon and faced with a shortage of ginseng at all times. Therefore, the shogun cultivated the Gasam systematically at the national level by the inside of the shogunate. However, since the natural ginseng is native to China and Korea, there is a concern about the deterioration of the quality of natural ginseng due to the incorporation of cultivated ginseng (Gasam). To protect the interests, the cultivation of ginseng was subject to control. For this reason, the lack of historical information on Gasam cultivation, which had to be started secretly, would be a natural result. In this paper, althouh not sufficient enough, the historical informations were used to summarize the history of ginseng cultivation in China, Japan and Korea.
