A infancy is the period in that growth and development of man are the most fast and neutrial requirement is the most big on his life. The insufficient neutrition of this period can have bad effect uppon man's whole life health not only physically but also pscychogenically and emotionally. Therefore a proper feeding at a proper time is very important to form the good food behavior and emotional development. The rate of using the commercial weaning food in Korea has gradually increased since 1970 and expected to be more increasing in future. In this paper, I investigate the general weaning status, stneutrial component and material content of infant weaning foods marketing in Korea at present. The material for this study have been collected in the exposition of products and data from manufacturing companies and etc. The conclusion is following. 1. The proper weaning period is from $4{\sim}6$ momth to 12 momth, but recently it is inclined to prolong. 2. In weaning methods, using a spoon is superior to using a bottle in food behavior and neutrial status. 3. The commercial weaning foods have two type, the powder type and formula type, but except gober's, all products marketing in Korea are the powder type and a sort of product is very simple. Therefore it is necessary to develp the more various kind of weaning foods, especially the formula type. 4. In the neutrial component, Son-Sik (flour of grain) cannot be up to international standards and the greater parts of weaning foods have too much suger over the standards.

The complexity and variability of both the biologicals and the bioassays used to test them led to the use of the reference standard- a sample of the product of defined purity and potency, against which all preparations of that product must be calibrated. In order to prepare and establish KFDA reference standard for recombinant human growth hormone (somatropin), somatropin substance was filled in ampoules in National Institute for Biological Standards and Control (NIBSC). The candidate KFDA reference standard for somatropin (designated as 98/674) was evaluated to determine the suitability of serving as a KFDA reference standard for somatropin by the collaborative study, in which 10 laboratories participated. Physicochemical analysis and in vivo bioassay were performed by direct comparison with the international somatropin standard 88/624. 98/674 was identified as somatropin by SDS-PAGE, IEF, peptide mapping, and HPLC. Determination of somatropin content by SE-HPLC yielded a mean estimate of 2.01 mg somatropin per ampoule. Data from the study also yielded mean values of 0.39 $\pm$ 0.26% for high molecular weight impurities by SE-HPLC and mean values of 2.13 $\pm$ 1.29% for somatropin related proteins by RP-HPLC. Estimates of relative potency by weight gain bioassay in the hypophysectomised rats showed that relative potency of KS 98/674 was 1.07 aganist IS 88/624. Based on the results of the collaborative study, the candidate reference standard for somatropin is suitable to serve as a KFDA reference standard for somatropin.

Sanitary codes of retail ffod establishment of Korea, Japan, China, and America were reviewed in order to figure out the differences of the codes. The codes of Korea & Japan are similar in many aspects. The code of America regulates food safety procedures in detail and are easy to interpret. The code of China is broad and not specific in the procedures. Korean code deals with many administration affairs and Japanese code deals with food test and business. Chinese code also deals with administration and standards. American code defines 90 different terms while the codes of rest of the countries define only few terms. For sanitization American code specifies the procedures in specific terms in detail but others do not specify the procedures. For facilities, the American code specifies location, material and procedures but other codes also specify the material but the contents of the codes are not so much specific to compare with American code.

This work is for reasonable valuation method of environmental-friendly and organic company. Reasonable valuation method is principal for the sound development, the reasonable investment and the growth of stock market. This study proposes valid valuation and method for environmental-friendly and organic company. The author selected 4 companies from certificate list of environmental-friendly and organic food and LOHAS (Lifestyles Of Health And Sustainability) food of Korean standards association. Applying financial audit report of 5 years, the author output 5 variables from each companies by using Growth Option model of Real Option model. And the author valuated companies by adding option value calculated with these variables and residual value discounted with cash flow discounted method. Company values from ROV model were 1.71 time higher than DCF model. This results show that the value of environmental-friendly and organic food company may own high option premium, that is the growth factor.

To enforce the maximum residue limit for residual hexane (0.005 g/kg) in commercially available Korean vegetable oil, convenient and accurate quantification methods were investigated. Using dual surrogate standards, pentane and heptane were dissolved in ethanol, and then added to hexane-tree sunflower oil for setting up the calibration curve. Gas Chromatograph-Flame Ionization Detector with a porous layer open tubular column, indicated good chromatographic separation of hexane from other inhibiting matrix components. The lowest calibration level was $0.5\;{\mu}g/g$, not exceeding a relative standard deviation of 10% (RSD%), and 1.0\;{\mu}g/g$ not exceeding a deviation of 22% RSD% using heptane as an internal standard for the Static headspace analysis by using a headspace auto-sampler and manual injection, respectively. The residual hexane was detected in nine of the samples among 87 vegetable oil samples purchased on the local market.

Changes in eating culture patterns has been observed among modern Koreans from seeking out traditional types of eating out restaurant to the modern, luxurious, and hybrid food. This study aimed to investigate the patterns of eating out and preference of food in Pusan National University (PNU) area, representing typical Patterns of eating out in Pusan. Data revealed that the most popular places in which the subjects visited were Korean traditional restaurants and snack bars. The names of the places were in trendy style of Korean connotation, with Intention to appeal to the new generation. The interviewee reported that decision making on choice of plates were made by taste, price, and service in that order. The frequency of eating out was once In two or three days, Korean traditional restaurants, noodle shops, and restaurants of offering fusion food being the Place of choice. Preferred reasons for the PNU area were reported to be low price, followed by variety of food offered and geographical accessibility to the places. Most of the interviewees in the area were satisfied with the taste of food and service quality. A list of food they were willing to introduce to oversea foreigners included raw fish, Dongrae Pajon, Pulgoki, Kimchi and dog soup in that sequence. The results of survey indicator that changes in the eating out environment in Pusan were improvement of service quality, development of new recipes, improvement of hygiene standards and development of area-specific food. The results may also act as a guide in changing the eating out environment and developing tourism in Pusan.

The physicochemical parameters of honey are used to determine the botanic origin of honey and to specify the composition criteria for honey in regulations and standards. The parameters of honeydew and blossom honeys from Korean beekeepers were determined to investigate whether they complied with the composition criteria for honey in the food code legislated by Korean authority and to establish the parameters which should be subjected to principal component analysis for improved differentiation of honeys. The fructose and glucose contents of the honeydew honey did not comply with the composition criteria. The ash content of the honey was closely correlated with CIE a^* and CIE L^* The principal component analysis of fructose to glucose ratio, CIE a^*, CIE L^*, ash content, free acidity, and fructose and glucose contents enabled classification of honeydew, chestnut, multifloral, and acacia honeys. Additional advantage of the principal component analysis (PCA) is that the physicochemical parameters, such as fructose to glucose ratio (F/G) and color, can be determined using the analytical instruments for composition criteria and quality control of honey. This study suggested that composition criteria for honeydew honey should be established in the food code in accordance with international standards. The principal component analysis reported in this study resulted in improved classification of the honeys from Korean beekeepers.

Japan launched its regulatory certification system for organic foods based on the amended JAS laws in June 2000, followed by the implementation of regulations on organic agricultural products and organic processed foods in January 2001 and with the implementation of the standards on organic animal husbandry and organic feed by the Ministry of Agriculture, Forestry & Fisheries in 2005, organic foods have been under integrated and systematic supervision. Certification of organic foods can be undertaken by registered accredited bodies (private certification bodies) or legal entities conforming to the regulations of the Ministry of Agriculture, Forestry & Fisheries. However, with the amendment of the JAS laws in March 2006, only legal entities conforming to the regulations of the ISO/IEC GUIDE 65 are eligible as certification bodies. Foreign organic products imported to Japan must be certified organic under JAS regulations and must be manufactured or produced by foreign manufacturers certified by local or foreign registered accredited organizations and distributed with the Organic JAS Mark affixed or through importers certified by local registered accredited organizations and distributed with the Organic JAS Mark affixed on the products. It can be implied from the Japanese case study that it necessary to reform the diverse agricultural products certification systems to set up an integrated certification system, and the restructuring of government organizations, reforms of environmentally-friendly agricultural products certification system and the integration of the organic food certification systems are needed in order to integrate the control of the standards and certification systems.
