To focus attention on milk and dairy products, we celebrate World Milk Day on the first day of June. Milk is a primary source of essential nutrients for newborn mammals, including humans. Milk and its by-products have been integral to human life since domestication of the dairy cow. Even though a large portion of the population is lactase impersistent, consumption of dairy products, including liquid milk, has been increasing over the last decade in Korea. Per capita annual consumption of dairy products in Korea increased to 61.3 kg in 2008, up from 49.4 kg in 1998. However, consumption of liquid milk has only increased marginally from 30.3 kg in 1998 to 35 kg in 2008. In 2007, the price of farm milk in Korea was the highest in the world. High dairy prices are forcing major manufacturers to find alternative, less expensive sources of milk, which has led to an increase in imported dairy products. Recently, the International Dairy Federation (IDF) published a special report containing the figures for world milk production, milk processing, and consumption. Understanding the current situation with regard to world diary production and the outlook for the industry could be useful during the present world economic crisis. The authors of this brief review summarize the status of dairy production in countries throughout the world, including Korea, along with some of the data published in the IDF annual report. The authors greatly appreciate the support of IDF Korea and the IDF for generously providing the data used in this paper.

Purpose: The purpose of this research was to test the effectiveness of the nursing intervention, mutual goal setting, for patients who have had a mastectomy. Special reference was given to King's goal attainment theory and a theoretical framework for establishing an effective nursing strategy to enhance patient recovery is suggested. Method: This research employed a quasi-experimental design which consisted of pretest-posttest non-equivalent control and experimental groups. Data were collected from 37 patients who had a mastectomy and were hospitalized in the Department of Surgery of Y Medical Center from January 2001 to May 2001. The experimental group received the nursing intervention, mutual goal setting four times from the day before the operation to the fifth day after the operation while the control group received only routine nursing care. As postoperative recovery indicators, ROM of arm joints, arm circumference, pain, physical symptoms, oxygen saturation stress, anxiety and body image were measured. Result: The test results are as follows : 1) there were statistically significant differences between the experimental and control groups in extension and internal rotation of the shoulder Joint and flexion of the wrist joint. 2) there was no significant difference between the two groups in arm circumference. 3) there were no significant differences between the two groups in pain, physical symptoms, or oxygen saturation. 4) there were no significant differences between the two groups in stress, anxiety, or body Image. On the basis of research results, the following are recommended : 1) The effectiveness of nursing intervention in the acute recovery period as well as long term effects need to be investigated. 2) There is a need to develop an instrument to measure perception which facilitates goal attainment in the interactive setting between patients and nurses.

Purpose: The aims of this study were to describe and interpret the nature of the experience inherent in the sex life of female breast cancer patients after treatment and understand the meaning behind it. Methods: The participants were 10 female breast cancer patients who were married. Data were collected from March to September 2010. Van Manen's hermeneutic phenomenology was adopted in this qualitative study as a research method. Results: There were 4 essential topics in the participants' experience of sex life; 'Sex life alert' was a result of negative changes in sexual relationships with spouse that they had never experienced before the breast cancer diagnosis; 'Precarious situation for pending divorce' was an experience of deteriorated sex life because of the failure to overcome 'sex life alert'; 'Sublimation of the difficulties by discovering an alternative solution' was an experience of discovering a solution to overcome the 'sex life alert'. 'Leaving it as unsettled' was an experience of a condition in which the participants did not have any intension to resolve the difficulties in sex life due to the lack of appropriate support, thus tried to ignore the challenges faced. Conclusion: This study illustrates the necessity to develop proper nursing intervention on the issues related to sex life among breast cancer patients. Given the fact that the sexual topics are often considered taboo in day to day nursing practice, special attention and efforts need to be given in this area to build up nursing knowledge and evidence-based practice.

In line with the establishment of the National Sejong Library, the main objective of this study is to construct a basic management plan to enable smooth operations of the library from its opening. To follow through with this goal, this paper analyzes the environment surrounding the National Sejong Library, puts forth new strategies to reinforce the policy information service, and suggests new development plans for the library's collection. This study examines the internal and external environment of the library through face-to-face interviews with library staff, while conducting surveys on public officials transferred to the city for suggestions on how to reinforce the policy information service. The vision of the National Sejong Library is to become a specialized resource institution in administrative policy, while also fulfilling the day-to-day needs of the community and serving as a supplementary record storage facility to the National Library. In order to reinforce the policy information service, it is crucial to digitize all policy-related theses, reports, and trend research, while establishing a firm network with other libraries in Korea and abroad to provide a wider range of policy files, local government policy documents, and other resources.

The effect of oral vitamin e (800IU/day) and C (500mg/day) supplementation for 10 days and/or smoking cessation for 5 days on oxidative damage to the red blood cells (RBC) of male smokers (22.2$\pm$0.2 years old) was studied. RBC were tested for their ability to protect against smoking-induced oxidative damage by measuring heme proteins (carboxyhemoglobin, hemoglobin, methemoglobin, oxyhemoglobin), hemolysis and thiobarbiturinc acid reactive substances (TBARS). Plasma levels of vitamin c, A, E, $\beta$-catotene, total cholesterol, glutamic pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase(GOT) were also analyzed. In experiment one, a comparison was made of heme proteins and lipid damage to RBC, plasma antioxidant status (indexed by plasma levels of vitamin C, E, A and $\beta$-carotene) between smokers(n=56) and non-smokers (n=16). No differences were found in plasma antioxidant status, heme protein damage and TBARS concentration of RBC. In experiment two, 46 fasting male smokers from experiment one were divided into 4 groups. The groups were smoking with placebo group(SP, n=14), smoking cessation with vitamins supplementatin group (SV, n=13), smoking cessation with placebo group (NSP, n=9) and smoking cessation with vitamins supplementation group (NSV, n=10). After supplementing antioxidant vitamins, significant increases were seen in plasma vitamins supplementation group (NSV, n=10). After supplementing antioxidant vitamins, significant increases were seen plasma vitamin C (p<0.05) and vitamin E levels (p<0.05). The plasma vitamin E level was highest in the NSV group. Vitmain E and C supplementation provided some protection against heme proteins and lipid damage by lowering methemoglobin, hemolysis and TBARS concentration of RBC. Smoking cessation significantly decreased TBARS of RBC and plasma total cholesterol concentration. Supplementing vitamin E and C with smoking cessation considerably lowered plasma total cholesterol. These results point to a special association among smoking, oxidative damage and plasma antioxidant vitamin status. They indicate that increases in plasma antioxidant status can be detected after the supplementation of vitamin C and E and that smoking cessation had an additional effect on plasma vitamin E level. The present data suggest that improved antioxidant status induced by antioxidant supplementation or smoking cessation may help prevent oxidative damage in smokers.

With increase of Korean economy scale and globalization, permanent alien residents in Korea are increasing day by day. Living in Korea, they maintain their original nationalities, but their life in Korea is greatly affected by political decision made by Korea. It has been taken for granted that foreigners's suffrage were not recognized due to national sovereignty. The claim that foreigners should not be allowed to participate in government has constantly been met with counterargument on the basis of instability of sovereignty principle, trends of advanced countries, intrinsic differences between federal and regional governments, or actual state of foreigners. It is unreasonable to deal with foreigners' suffrage and eligibility for election differently in that the current public offices election law does not allow foreigners to be eligible for election without any special reason while allowing foreigners to vote in the local election. It is discrimination against foreigners not to allow foreigners to be eligible for election when there is no rationale to differently deal with foreigners' suffrage and eligibility for election. This paper deals with constitutional argument regarding foreigners' electoral eligibility, takes a look at legislative cases of Japanese and European countries, and examines possibilities of including foreigners' eligibility for election in our public offices election law.

The protein nutritional quality of foods has become an important factor to food processors with the advent of nutritional labeling regulations for foods. Then, as is true today, the officially approved assay for protein nutritional quality was the rat based protein efficiency ratio(PER) bioassay. The PER bioassay requires a minimum of 28 days to performe, and is therefore not applicable to routine quality assurance use by the food industry. Within the past ten years there has been a research emphasis placed on the development of rapid, inexpensive, biological and/or chemical based assays for protein nutritional quality. It was hoped that if a rapid assay could be developed and thoroughly tested, it could be used in lieu of the PER bioassay in the day-to-day quality assurance screening of food ingredients and products. The rapid assays developed in the hope of attaining this goal have been based on microorganisms, proteolytic enzymes, and amino acid profiles, as well as combinations of the above. In this review, it will be described and briefly discussed many of procedures which had contributed conceptually as well as practically to the development of in vitro methods for the evaluation of protein quality. Special emphasis will be placed on the C-PER(computed protein efficiency ratio) assay which combines data from in vitro protease digestion and amino acid composition to predict protein nutritional quality designed by Satterlee et al. (1980), and the DC-PER(discriminant computed PER) which is a method of estimating protein quality based on rat assay and in vitro digestibility obtained using solely essential amino acid data will be also introduced.

A liquid chromatographic method with tandom spectrometric detection (LC/MS/MS) for the simultaneous determination of doxifluridine and its active metabolite, 5-fluorouracil (5-FU) was developed over the concentration range of $5{\sim}2000$ ng/ml, respectively. Doxifluridine, 5-FU and internal standard, 5-chlorouracil (5-CU), were extracted from liver and intestine tissue via protein precipitation. Acetonitrile was used as the extraction solvent and the supernatant was evaporated and reconstructed in mobile phase. Optimum chromatographic separation was achieved on a Agilent Zorbax $C_{18}$ ($100\;mm{\times}2.1\;mm$, $3.5\;{\mu}m$) column with mobile phase run in isocratic with methanol : water (20 : 80, v/v). The flow rate was 0.2 ml/min with total cycle time of 5 min. The lower limit of quantification was validated at 5.0 ng/ml of liver and intestine tissue, for both doxifluridine and 5-FU, respectively. The intra-day and inter-day precision and accuracy of quality control (QC) samples were <11% coefficient of variation and <7% relative error from theoretical concentration for both analytes. In addition, the special designed stability study was performed, because the metabolism of doxifluridine occurs spontaneously even in ice bath for monkey liver. The stability of doxifluridine in liver and intestine of monkey and beagle dog was compared. It was found that bioanalytical validation could not be performed for the monkey liver; however, beagle dog's liver has relatively low speed of metabolism compared to monkey liver and instead of monkey liver, beagle dog's liver could be used for the validation. Bioanalytical validation could be performed in monkey intestine. Eventually, this developed method for liver and intestine will be useful in support of the toxicokinetic and pharmacokinetic studies of doxifluridine and 5-FU.

The purpose of this paper is to discuss the function of microclimate amelioration of urban trees regarding the environmental benefits of street trees in summer, focusing on the heat pollution-urban heat island, tropical climate day's phenomenon and air pollution. We measured the diurnal variation of air/ground temperatures and humidity within the vegetation canopy with the meteorological tower observation system. Summertime air temperatures within the vegetation canopy layer were 1-2$^{\circ}C$ cooler than in places with no vegetation. Due to lack of evaporation, the ground surface temperatures of footpaths were, at a midafternoon maximum, 8$^{\circ}C$ hotter than those under trees. This means that heat flows from a place with no vegetation to a vegetation canopy layer during the daytime. The heat is consumed as a evaporation latent heat. These results suggest that the extension of vegetation canopy bring about a more pleasant urban climate. Diurnal variation of air/ground temperatures and humidity within the vegetation canopy were measured with the meteorological tower observation system. According to the findings, summertime air temperatures under a vegetation canopy layer were 1-2$^{\circ}C$ cooler than places with no vegetation. Due mainly to lack of evaporation the ground surface temperature of footpaths were up to 8$^{\circ}C$ hotter than under trees during mid-afternoon. This means that heat flows from a place where there is no vegetation to another place where there is a vegetation canopy layer during the daytime. Through the energy redistribution analysis, we ascertain that the major part of solar radiation reaching the vegetation cover is consumed as a evaporation latent heat. This result suggests that the expansion of vegetation cover creates a more pleasant urban climate through the cooling effect in summer. Vegetation plays an important role because of its special properties with energy balance. Depended on their evapotranspiration, vegetation cover and water surfaces diminish the peaks of temperature during the day. The skill to make the best use of the vegetation effect in urban areas is a very important planning device to optimize urban climate. Numerical simulation study to examine the vegetation effects on urban climate will be published in our next research paper.

Bone morphogenetic protein-7(BMP-7), a member of the transforming growth factor superfamily, stimulates osteoblast differentiation and bone formation. There are lots of evidences supporting a direct participation of periodontal ligament(PDL) cells on periodontal tissue regeneration. The purpose of this study was to evaluate the effect of recombinant human(rh) BMP-7 on primary rat PDL cells in vitro, with special focus on the ability of bone formation. The PDL cells were cultured with rhBMP-7 at the concentration of 0, 10, 25, 50, 100 and 200ng/ml for MTT assay. We evaluated the alkaline phosphatase activity at 3 and 5 days of incubation and the ability to produce mineralized nodules of rat PDL cells at 14 days of cell culture in concentration of 0, 10, 25, 50 and 100ng/ml. The cell activity was not reduced in cells treated with BMP-7 at $10{\sim}100ng/ml$, whereas the cell activity was reduced in the concentration of 200ng/ml than the control at day 1 and 3(p<0.01). At 3 and 5 day, alkaline phosphatase activity was significantly increased in cells treated with BMP-7 at 50ng/ml and 100ng/ml(p<0.05). The area of mineralized bone nodule was greater in cells treated with BMP-7 at 50 and 100 ng/ml than the control(p<0.01). These results suggest that rhBMP-7 stimulate rat PDL cells to differentiate toward osteoblast phenotype and secretion of the extracellular matrix of rat PDL cells.
