As it is expected that change in trade environment has a significant impact on Korean economic growth as well as foreign trade of Korean economy we need an appropriate political response to it. Therefore, this study aims to analyse the Export Competitiveness of IT Industry to China and our trade policy. Korean balance of trade to China in 2007 records surplus of 18.9 billion dollars. However, many experts estimate unfavorable balance of trade will appear from 2010. In consideration of this condition, this study suggests a desirable trade policy for long-term maintenance of current Export Competitiveness between Korea and China. Using TSI and RCA, it analyses a Export Competitiveness of IT Industry to China from 2003 to 2007. To sum up the results, the TSI has been declining since 2005. RCA of semi-conductors has been declining since 2005 while that of communication equipment and computers has been increasing. During the analysis period, the mean RCA of semi-conductors is 55.01, which indicates that its export advantage is somewhat weak, and the mean RCA of communication equipment and computers are 227.22 and 175.83 respectively, which indicates that their export advantage is very strong. Production and export of Korea IT industry have greatly increased in quantity, but its technological quality and diversity have not been satisfactory. In particular, the base of IT industry is growing weaker due to serious dependence of core spare parts on advanced countries and transfer of simple assembly plants to China. To maintain export competitiveness of IT industry, we should pay more attention to technological improvement through more investment to the original technology for local production of core spare parts.

In scheduling multi-unit projects, several alternatives can exist in network construction due to repetitiveness of their activities. Project duration is affected not only by the duration of each activity but also by the arrangement of repeating activities in such projects. This paper provides a network compression method that assigns predecessors to each activity to minimize its float time. Different to the previous efforts that utilized line of balance as the base scheduling-model, this research adopts precedence diagram arranged in two coordinates, the space axis and the resource one. This method seeks the most appropriate predecessors for each activity in each direction of the two coordinates for the purpose of minimizing the idle resource and space. This activity arrangement method was applied to a multi-unit apartment-construction project, to prove its capability of network compression. The result shows that the method successfully sought room for saving construction duration by changing the activity arrangement. The network compression method presented in this research can be utilized in multi-unit construction projects such as apartment complex projects.
Occlusion force measuring and analysis is a diagnostic method of tooth dynamics through the related force analysis. In this paper, we design and implement a series of occlusion force measuring software and evaluate its utility as a base system for a new occlusion force measure and analysis system development. For the reason, we developed a group of tools to measure the normal and abnormal occlusion force. Firstly, we have visualized the occlusion force distribution with quantitative figures. The center of force (COF) variation was visualized the path of marker according to teeth dynamics and the distribution of occlusion forces in 14 tooth regions. Secondly, we have implemented a left and right tooth force balance measurement ratio tool to estimate a specific tooth region force. Furthermore, the measured occlusion force variation recorded in the software each 0.5 second. As the result of the physical examination by the accessed hardware of sensor sheet method, we confirmed the distribution and balance of forces effectively.

Teacher quality is a topic of international concern, as it impacts student learning and teacher preparation. This study compared the undergraduate secondary science teacher preparation programs from two universities in Korea with those of Oregon, USA. We examined the programs' structural curricular coherence, conceptual curricular coherence, and curricular balance. Structural curricular coherence was determined by examining the overarching goals of the institutions' programs, the organization of the programs of study in terms of meeting those goals, and outside bodies of evidence. All universities were in structural coherence for various reasons. Conceptual curricular coherence was determined by examining students' perceptions of the connection between their preparation and their clinical practice. In case of Korea, most students from both universities were not satisfied with their practical preparation. In the US, the students from both institutions felt well prepared to transition to inservice teaching. To determine curricular balance, we examined the institutions' preparation programs looking at the credit hours taken in the four main areas of the teacher knowledge base: GPK (General Pedagogical Knowledge), SMK (Subject Matter Knowledge), PCK (Pedagogical Content Knowledge), and CK (Contextual Knowledge). The total credit hours taken in each category was very similar by country but the application and field component in the USA was far greater than those of Korea where the focus was heavily on SMK and PCK. The main reason for these may be the nations' licensing and employment processes.
The Sasang Constitutional Medicine seeks the psychosomatic balance, and the Basic principle of treatment according to the symptom(病證藥理) in Sasang Constitutional Medicine could be summarize as follows. 1. The pursuit of Shape-Image Medicine (形象醫學) and the Symptoms of shape - Symptoms of disease (形置病證). It established emotion, symptoms of constitution, and symptoms of constitutional disease on the base of Shape-Image Medicine (形象醫學) which means qi (氣) is inside and shape is outside (氣裡形表). 2. The inductive medicine and positive medicine. It systematized the Symptoms of shape - Symptoms of disease (形證病證) on the base of the medical practice of the ancients and Lee Jae-Ma (李濟馬)'s own experience inductively, and it present show to control the psychosomatic balance practically. 3. The pathology centering on human. Oriental medicine is based on Yin-Yang (陰陽) and Five elements (五行) and the harmony of nature and human (天人相應) of Taoism, but Sasang Constitutional Medicine is based on emotional and ethical pathology of Confucianism (儒學). 4. The treatment according to the symptom (病證藥理) in Sasang Constitutional Medicine centering on clear qi (正氣). The promotion and demotion (補瀉) which is based on clear qi (正氣) and evil qi (邪氣) is a basic principle in Oriental medicine, but In Sasang Constitutional Medicine it is attached importance to control of clear qi and classify obedience symptom and disobedience symptom (順 逆症) as the type to oppose disease. 5. The treatment according to the psychomatic symptoms. It takes importances to control of one-sided emotion as well as the treatment of psychical symptoms, and also to remedy disease as keeping under control one's mind. 6. The preventive medicine and the medicine to develop one's health. It is in pursuit of social health to develop personality through clear qi (正氣) in real life, to prevent disease, and to spread the sickness control of individual person. Sasang Constitutional Medicine pursuits the psychosomatic balance through 'Balance', 'Control', 'Self regulating Control' of the 'Golden Mean (中庸)' with the treatment according to the symptom (病證藥理) in Sasang Constitutional Medicine.
The fluxes of wet deposition(WD), throughfall(TF), stemflow(SF) and soil leachates were measured to understand base cation budgets on deciduous ecosystem impacted by acidic deposition in the north-western part of Tomakomai in Hokkaido, Japan. The flux of $H^{+}$ for wet deposition was $0.34kmo1_{c}$$ha^{2+}$ and the flux of base cation, $K^{+}$ /, Na$^{ + }$, $Ca^{2+}$ and $Mg^{2+}$ far throughfall plus stemflow wart 1.6 kmolc $ha^{-1}$ , 3 times higher level than that for wet deposition. The flux of base cation for canopy leaching(LI) was 0.95 kmolc ha$^{-1}$ , 2.8 times higher level than $H^{+}$ sources in wet deposition. The major mechanism of $^{+}$ consumption closely related to acidic neutralizing capacity of canopy. The ionic flux for soil leachates from Boil reservoir and proton consumption in soil was dependent on soil chemical states and exchangeable Ca in soil had a major factor of H$^{+ }$ consumption. The base cation budgets on deciduous ecosystem showed positive balance fur Na, Ca and Mg, while K was the negative value.
The treatment of pediatric patients with chronic renal disease comprises management of nutritional imbalance, fluid, electrolyte, and acid-base disturbances, mineral bone disease, anemia, hypertension, and growth retardation. The treatment also includes administration of appropriate renal replacement therapy, if required. Adequate dietary intake of carbohydrates, fats, and proteins and caloric intake must be encouraged in such patients to ensure proper growth and development. In addition, fluid, electrolyte, and acid-base status must be regularly monitored and should be well maintained. Serum calcium, phosphorus, and parathyroid hormone levels must be maintained at their target range, which are determined on the basis of the glomerular filtration rate, to avoid the development of mineral bone disease. This can be achieved by using phosphorus binders and vitamin D analogues. An erythropoiesis-stimulating agent must be administered along with iron supplementation to maintain the hemoglobin level of the patients between 11-12 g/dL. Hypertension must be controlled with adequate water and sodium balance and appropriate antihypertensive agents. Administration of recombinant human growth hormone is recommended to improve the final adult heights.

Processes controlling the interannual variation of mixed layer temperature (MLT) averaged over the NINO3 domain ($150-90^{\circ}W$, $5^{\circ}N-5^{\circ}S$) are studied using an ocean data assimilation product that covers the period of 1993 to 2003. Advective tendencies are estimated here as the temperature fluxes through the domain's boundaries, with the boundary temperature referenced to the domain-averaged temperature to remove the dependence on temperature scale. The overall balance is such that surface heat flux opposes the MLT change but horizontal advection and subsurface processes assist the change. The zonal advective tendency is caused primarily by large-scale advection of warm-pool water through the western boundary of the domain. The meridional advective tendency is contributed mostly by Ekman current advecting large-scale temperature anomalies though the southern boundary of the domain. Unlike many previous studies, we explicitly evaluate the subsurface processes that consist of vertical mixing and entrainment. In particular, a rigorous method to estimate entrainment allows an exact budget closure. The vertical mixing across the mixed layer (ML) base has a contribution in phase with the MLT change. The entrainment tendency due to temporal change in ML depth is negligible comparing to other subsurface processes. The entrainment tendency by vertical advection across the ML base is dominated by large-scale changes in wind-driven upwelling and temperature of upwelling water. Tropical instability waves (TIWs) result in smaller-scale vertical advection that warms the domain during La Ni? cooling events. When the advective tendencies are evaluated by spatially averaging the conventional local advective tendencies of temperature, the apparent effects of currents with spatial scales smaller than the domain (such as TIWs) become very important as they redistribute heat within the NINO3 domain. However, such internal redistribution of heat does not represent external processes that control the domain-averaged MLT.
Purpose: The main question is systematic review of the published in Korea and foreign countries on warming therapy for surgical patients. Methods: The researchers searched at Medline, CINAHL, KERIS, Adult Nursing Association, Korean Society of Nursing Science, Korean Academy of fundamentals of Nursing, and National Assembly Library web site for the published on warming therapy for surgical patients from 1980 to 2008. Words for search were operation/surgery, warming, operation/surgery and warming. Studies were included randomized controlled trial, and there were no restrictions regarding operative phase and outcome measures. Results: 36 published researches that met the criteria were mostly published in foreign countries between 2000 and 2008 and focused on surgery with general anesthesia. Sample size ranged from 21 to 60 subjects, age range between 21 and 60 years of age. Thirty different warming therapies were reported, fifty-two different dependent variables. Outcome indicators included active external warming, intra-operative, and body temperature. 'Positive effects' and 'no effects' equaled. The most frequently reported 'positive effects' were body temperature, shivering, and acid-base balance. No effects were more likely to be heart rate, blood pressure, and hemodynamics. Conclusion: Many types of warming therapy, are reported in the literature with little information about the efficacy of each, many different dependant variables were studied. There were no consistent reports as to length of time used for warming procedures. Overall, the effects of warming therapy are inconsistent. And additional research must be down before any particular method of warming can be used with confidence as to its effectiveness. Attention must be made as to the research design, better measurement of the dependent variables. This review may serve as a base.
Acute renal failure refers to a rapid reduction in renal function that usually occurs in an individual with no known previous renal disease. Development of a complication of acue renal failure in critically ill surgical patients is not unusual, and it causes high morbidity and mortality. Acute renal failure can be divided as Pre-renal (functional), Renal (organic), and Post-renal (obstructive) azotemia according to their etiologies. Early recognition and proper correction of pre-renal conditions are utter most important to prevent an organic damage of kidney. These measures include correction of dehydration, treatment of sepsis, and institution of shock therapy. Prolonged exposure to ischemia or nephrotoxin may lead a kidney to permanent parenchymal damage. A differential diagnosis between functional and organic acute renal failure may not be simple in many clinical settings. Renal functional parameters, such as $FENa^+$ or renal failure index, are may be of help in these situations for the differential diagnosis. Provocative test utilyzing mannitol, loop diuretics and renovascular dilators after restoration of renal circulation will give further benefits for diagnosis or for prevention of functional failure from leading to organic renal failure. Converting enzyme blocker, dopamine, calcium channel blocker, and propranolol are also reported to have some degree of renal protection from bioenergetic renal insults. Once diagnosis of acute tubular necrosis has been made, all measures should be utilized to maintain the patient until renal tubular regeneration occurs. Careful regulation of fluid, electrolyte, and acid-base balance is primary goal. Hyperkalemia over 6.5 mEq/l is a medical emergency and it should be corrected immediately. Various dosing schedules for medicines excreting through kidney have been suggested but none was proved safe and accurate. Therefore blood level of specific medicines better be checked before each dose, especially digoxin and Aminoglycosides. Indication for application of ultrafiltration hemofilter or dialysis may be made by individual base.
