The ICT policy domain is one of the most important policy domains in terms of national development and continuity. It is primarily because the contemporary society has been continuously developed and changed based upon the advanced information technologies. Recently, the Moon Jae-in Administration reorganized the Ministry of Science and ICT, and transferred a few of the key ICT related functions to other ministries as an attempt to develop the national ICT policies. However, critics in this domain argue that various problems still exist in the ICT policies in Korea. Therefore, the purpose of this research is to verify the empirical validity of the existing problems in the ICT policies in Korea, and develop alternatives to solve those problems. In order to serve the research purpose, this study employs multiple methods; a quantitative method which is a survey involving experts in ICT policies, and a social network analysis involving public officials in ICT related ministries. Research results show that the Korean government needs to enhance its capacity to make adjustments in ICT-related policies as the current decentralized system continuously creates various types of problems. The second possible solution to the problem is to change the national ICT policy system to a centralized one. However, this requires various efforts such as cooperation among ICT related government agencies, separation of ICT policies from science and technology policies, and increased government capacity to implement the ICT policies.

This article aims to analyze the diplomatic challenges currently facing China as well as the foreign policy the Xi Jinping administration is adopting to address them. With these purposes in mind, it will look into three areas: first, diplomatic tasks confronting the Xi leadership; second, foreign policy that the Xi administration has implemented since the 18th Party Congress in 2012; and third, the prospects for China's foreign policy under the Xi leadership. As the Xi Jinping administration entered into office, it has encountered two major diplomatic challenges. One is the searching for a new foreign policy, and the other the restructuring of the existing foreign affairs and national security systems. The Xi administration, during its first year in office, has responded actively to tackle these issues. To begin with, it has attempted to make some adjustments on foreign policy while maintaining the Deng Xiaoping line of foreign policy. One of these modifications is placing emphasis on national "core interest," as illustrated by changes in guideline for maritime conflicts, pushing for building maritime power, and proclamation of Air Defense Identification Zone in the East China Sea. Second is the decision on the new guideline for peripheral diplomacy. That is, the administration regarded creating peaceful and stable environments to realize "Chinese Dream" as an important goal of foreign policy, and proposed such new guiding ideology as "familiarity, integrity, benefit, and accommodation." In additoin, the Xi administration restructured the existing foreign affairs and national security systems. Establishing the Central State Security Committee and the Internet Leading Small Group (LSG) are cases in point. As comprehensive organizations for policy coordination that encompass party, government, and military, the two LSGs are in charge of enacting related policies and fine-tuning policy implementation, based upon leadership consisting of chiefs of each relevant organs. Moreover, since Xi himself became the chief of these two newly-found organs, the conditions under which these LSGs could demonstrate unified leadership and adjusting role in its implementation of military, diplomatic, and security policies were developed. The future Chinese diplomacy will be characterized with three main trends. First, peripheral diplomacy will be reinforced. The peripheral diplomacy has become far more important since the Work Conference on Peripheral Diplomacy in October 2013. Second, economic diplomacy will be strengthened with an eye on reducing the "China Threat Theory," which still exists in Asia. Third, the policies to isolate the Philippines and Japan will continue in regard to maritime disputes. All in all, Chinese diplomacy in the Xi Jinping era is likely to feature practical diplomacy which combines both hard and soft approaches to best realize Chinese national interest.

The guarantee of transportation for elderly and handicapped people is increasingly necessary owing to their growing social and economic activity. In March of 2013, a partial amendment to the law for transportation of the vulnerable was made by the government, to make more convenient transport a legal requirement. The amendment describes standards for the installation of transport facilities, and its support available. However, the adjustment of low-floor bus routes is not included. Therefore, low-floor buses are operating without consideration for the handicapped. This study evaluates the current low-floor bus system user experience by considering the residential distribution of vulnerable customers and analyzing their reasons for using public transport. As a result of this work, adjustments to current bus routes are proposed. The residential distribution of vulnerable people has been assessed using the supporting materials of the urban renewal project in Busan City, and their reasons for using public transport have been collected by a survey of the target user groups. The results show that group A, which has good accessibility, was in high demand, but provided the most limited service. Whereas group C, which also has good accessibility but was in low demand, provided its service most frequently. The data show the supply and demand inconsistencies of low-floor buses, and the inefficiency of bus route allocation. Therefore, this study proposes improvements to current methods for the effective operation of low-floor buses.

Sexual life is one of the most important things for the quality of living, which nobody can ignore. Especially, spinal cord injury is one of the most typical disabilities, which can cause abrupt changes of sexuality. Hence, sexual adjustment and its subordinate problems have to be dealt with among various problems caused by spinal cord injury. The purpose of this study was to comparative sexual interest and adjustment between the married and the unmarried people with SCI. A total of 134 persons who were registered members of SCI organization and admitted rehabilitation unit between February and June 1999 were included in the study. The sample consisted of 69 unmarried and 64 married people with SCI. Participants answered the 15 items concerning sexual interest, sexual adjustment. The results are as follows: 1) The mean score of sexual interest for the unmarried was 16.4. From seven topics related to sexuality, the greatest interest was to cope emotionally with changes in sexual functioning. For the married, mean score of sexual interest was 13.8 and the greatest interest was to help a partner cope emotionally with limitation on sexual dysfunction. There were significant difference sexual interest between two groups (t=3.75, p= .00). 2) Each mean score for sexual adjustment in the married and the unmarried was 20.0, 19.6. There were no significance difference sexual interest between two groups (t=.24, p= .811). However, there was a statistically significant difference of sexual interest. 3) Sexual interests and adjustments are not correlated in case of the unmarried that have r score= .224, while they are corrlated in case of the married that have r= .398. Because the average age of the SCI becomes lower and lower, sexual rehabilitation programs should be given the unmarried as well as the married with SCI. In conclusion, the spinal injured's major concerns about their sexual life are different between the married and the unmarried-the unmarried are interested in practical problems such as methods and techniques to achieve sexual satisfaction and their fertility, while the married give priority to considerations about their spouse. Paying attention to different sexual interest according to marital status, we should make two different sexual rehabilitation programs for each group. One program including support groups with their sposes for the married, the other program to give a chance t o solve problems of sexuality for the unmarried with SCI.

The study was conducted to analyze the genetic parameters of somatic cell score (SCS) of Holstein cows, which is an important indicator to udder health. Test-day records of somatic cell counts (SCC) of 305-day lactation design from first to fifth lactations were collected on Holsteins in Korea during 2000 to 2012. Records of animals within 18 to 42 months, 30 to 54 months, 42 to 66 months, 54 to 78 months, and 66 to 90 months of age at the first, second, third, fourth and fifth parities were analyzed, respectively. Somatic cell scores were calculated, and adjusted for lactation production stages by Wilmink's function. Lactation averages of SCS ($LSCS_1$ through $LSCS_5$) were derived by further adjustments of each test-day SCS for five age groups in particular lactations. Two datasets were prepared through restrictions on number of sires/herd and dams/herd, progenies/sire, and number of parities/cow to reduce data size and attain better relationships among animals. All LSCS traits were treated as individual trait and, analyzed through multiple-trait sire models and single trait animal models via VCE 6.0 software package. Herd-year was fitted as a random effect. Age at calving was regressed as a fixed covariate. The mean LSCS of five lactations were between 3.507 and 4.322 that corresponded to a SCC range between 71,000 and 125,000 cells/mL; with coefficient of variation from 28.2% to 29.9%. Heritability estimates from sire models were within the range of 0.10 to 0.16 for all LSCS. Heritability was the highest at lactation 2 from both datasets (0.14/0.16) and lowest at lactation 5 (0.11/0.10) using sire model. Heritabilities from single trait animal model analyses were slightly higher than sire models. Genetic correlations between LSCS traits were strong (0.62 to 0.99). Very strong associations (0.96 to 0.99) were present between successive records of later lactations. Phenotypic correlations were relatively weaker (<0.55). All correlations became weaker at distant lactations. The estimated breeding values (EBVs) of LSCS traits were somewhat similar over the years for a particular lactation, but increased with lactation number increment. The lowest EBV in first lactation indicated that selection for SCS (mastitis resistance) might be better with later lactation records. It is expected that results obtained from these multi-trait lactation model analyses, being the first large scale SCS data analysis in Korea, would create a good starting step for application of advanced statistical tools for future genomic studies focusing on selection for mastitis resistance in Holsteins of Korea.

Background : The origin of P300 was still on debate nbut thought to be in the frontal, temporal or parietal lobe. As the transcranial doppler ultrasonography(TCD) gives us and opportunity to observe hemodynamic chaged dynamically and the middle cerebral artery feeds these ares of the hemisphere, we observed the change of mean flow velocity of MCA during the event related potential test(ERP) to determine the role of these structures in P300 generation. Method : Twenty normal subjects(male : 13, age : 24-29 years) performed ERP. An auditory oddball pardigm was used to elicit the ERPs. TCD examination was performed with 2-MHz probe monitoring the left MCA(Transscan, EME). After signal identification and adjustments to maximize the Doppler signal strength, the probe was mechanically locked during the monitoring. The changes of blood flow velocity of the left middle cerebral artery(MCA) induced by cognitive demands were monitored. The measurement of the meal flow velocities(MFV) of MCA were made while the subjects were prior to, during, and after ERP. We recorded the MFVs during ERP. Statistical analysis was performed using t-tests with SPSS-PC for windows release 6.0. Results : All subjects showed a relative increase in MFV of MCA during the task. The mean rise was about 3.2-4.2%(p <0.05). Although TCD does not measure absolute values of regional cerebral blood flow(rCBF) or absolute rCBF changes, changes of flow velocity can reflect relative rCBF changes. Conclusions : The generation site of P300 still remains unclear but the neocortical, thalamic and limbic region and temporal-parietal cortex have been proposed. The MCA supplies these anatomical structures. The Changes of flow veolocity of MCA during the ERP test suggest that the some part of the brain fed y the MCA activate of the temporal lobe or parietal lobes, we can deduce that some parts of brain fed by the MCA participate in the generation of P300.

Germination and seedling growth of chinese milkyetch (Astragalus sinicus L. Line A) seeds were measured at four temperatures (15. 25. 30, and 35$^{\circ}C$), three polyethylene glycol (PEG) 10.000 (MW) solutions (0, 20 and 25 g/100$m\ell$ H$_2$O), and five sulfuric acid treatments (conc, H$_2$SO$_4$: Seeds/weight base: 0, 1:1 10min.. 1:1 20min.. 1:1.5 10min. and 1:1.5 20min, immersion), Adjustments of PEG 10.000 solutions were based on water potentials of 0.0, -0,5 and -0.8 ㎫ at room temperature. Observations were taken at 7 days for each treatment combinations. Germination percent of chinese mikvetch seeds was the highest at 15$^{\circ}C$ and seeding length was the longest at 25$^{\circ}C$. Both germination percent and seedling length were rapidly decreased as PEG concentration increased from 0 to 25g/100$m\ell$ H$_2$O. The highest germination percent was found at PEG 20 and 25 of 15$^{\circ}C$ among those of four temperatures, Sulfuric acid treatments showed little effect on germination percent and seedling length compared to untreated control, However. in the case of PEG 0, greater germination perccent was obtained at the treatment of 1:1.5 for 10 minutes immersion, The result of this study-indicated that germination of chinese milkvetch seeds was affected mostly by moisture stress conditions.

This paper suggests a normative performance measurement model for B2B e-marketplace. The model is for the neutral and systematic sourcing B2B e-marketplace. It is based on BSC that is very powerful and sound tool among all the available performance measurement systems. In addition, we used AHP to make the model more structured and to draw weights of performance measures from experts. We derived main features and factors affecting performance of e-business companies and especially of B2B e-marketplaces based on literature. In order to make the model usefulness, we co-worked with some experts who are engaged in real Korean B2B e-marketplaces. They included venture capitalists, top managers of B2B e-marketplaces, and consultants. By their assistances, we could find important evaluating factors and define the hierarchical structure. After defining the hierarchical structure, the expert group decided weights of performance indicators through the designed questionnaires. The weight for each measure was calculated using geometric mean of the questionnaire response. We made the case studies of two real Korean B2B e-marketplaces to apply the suggested model with some adjustments. The results of the case studies were so satisfactory that the suggested performance measurement model for B2B e-marketplace is useful and applicable to the real world.

This experiment was conducted to study the optimum energy feeding regimens fur broiler breeders peaked in winter season with 400 caged hens of Ross strain. Four energy supply regimens which were different in daily energy allotment during laying period were employed for 40 weeks from 24 to 64 weeks of age. All experimental diets were formulated to contain 2,750 kcal ME/kg with adjustments made in total feed allotment to provide the desired energy levels. Total consumption of the feed would provide 20 g of protein, 4 g of calcium and 0.35 g of available phosphorus. There were no difference in hen-day egg production and average egg weight among the regimens of energy supply. Feed, ME and feed cost required per egg or per kg egg were significantly increased as the level of energy allotment increased(p<0.05). It was concluded that the energy supply regimen, which supplied 280 kcal ME per day at the age of 24 weeks and then increased the energy supply up to 400 kcal ME per day at the peak period of 30∼34 weeks of age, was superior in feed, ME and feed cost required per egg or per kg egg without any adverse effect on eg production and egg weight.

We present extraction process and reaction mechanism of boric acid from one of calcium borate ores, colemanite by reaction with sulfuric acid. Colemanite has been fully decomposed under pH 5 with sufficiency amount of sulfuric acid, more than the amount stoichiometrically required. Calcium sulfate was separated out, leaving boron in the liquid phase after sulfuric acid addition. The extraction process of boric acid was affected by dissolution temperature and time, amount of sulfuric acid and ammonium sulfate, pH and a degree of concentration before recrystallization. The $SiO_2$ of the impurities which colemanite contains was insoluble so that it was separated out with calcium sulfate from liquid phase. The species of $CaO,\;Al_2O_3,\;Fe_2O_3,\;MgO$ were remained in a liquid phase after reaction with sulfuric acid. These impurities were separated out by addition of ammonia to the liquid phase, funhermore, boric acid was produced by process of pH adjustments and acidification, concentration, and recrystallization.
