Mathematics education is very important in future because mathematics is the basis of every study, for example, natural and social science, etc. Our nation wide curriculum has been revised six times since 1948. In 1992, the sixth revision was enforced and we are using the revised textbook now. This study aims at helping of continuous investigation for educational curriculum and textbook, and aims at efficient teaching by preventing unnecessary repetition and excessive gap in real field by analyzing the articulation of Analytics part in school textbook from elementary to high school. This thesis consists of the followings. 1.Investigation of the principles and natures of articulation along with curriculum course and notice the articulation based on the analysing tools. 2.Importance of learning functions. 3.To get the propriety, formation of 8 judging group and classification of content materials in function chapters by the judges based on the analyzing tools. 4.Analysis of presentation method and terminologies in the first concepts, suggestion teaching method to reduce gap and help of understanding on first concepts in the study of function. As a result 'development' consists of 55.8% of the total and it is higher than 'duplication' and 'gap'. To be specific in periods, between elementary school and middle school 'development' takes 64.5% and this shows an acceptable articulation in the period. While 39.4% of 'gap' in articulation between middle school and high school looks high compared with 'gap' between the previous periods. The item suggested with the 'gap' is the 'definition of function', 'value of function', 'parallel translation', 'exponential and logarithmic function'. It is observed that these materials is suddenly appeared in high school.

The year of 1998 was a very hard time for the most of Koreans. The rate of unemployment, which had averaged between 2 and 2.5 percent for many years, has continued to rise as the industrial production declined from the first quarter of 1998. The seasonally unadjusted unemployment rate recorded high of 8.4 percent in the first quarter of 1999, and the number of the unemployed as 1.75 million. On the other hand, the unemployment rate in Kangwondo used to be smaller than the nation-wide rate. However, this should not be taken as evidence that Kangwondo's economy used to perform better than others, because the participation rate also used to be smaller in Kangwondo than other regions. Anyhow, the unemployment problem is one of urgent issues in Korean society. The purpose of this paper is to overall review Kangwondo's unemployment counterplan and to make priorities about what we have to do against the long-run unemployment. In addition to implementing unemployment countermeasure of the central government, Kangwondo has to devise in itself unemployment counterplan reflecting local attributes.

Through concentrated investments in environmental regulations centered around BOD, which is a biodegradable matter index, and basic environmental infrastructures, national BOD pollution level has continuously improved. Nonetheless, limitations of BOD management system has become evident through nation-wide stagnation and/or increases of refractory organic matters, such as COD, at main drinking water sources, and the need for a new index, which can easily indicate different environmental conditions, has increased. Therefore, this study suggests a new organic management index for a proper management of surface water. $COD_{Cr}$ and TOC were examined as candidates for surface water quality management index, and it was found that TOC was more appropriate than $COD_{Cr}$ as an organic matter management index. Through this study, it was found that TOC possesses following qualities: a more representative index; international acceptability; monitoring program is easier; better availability of analysis techniques; better accuracy and precision of analysis; less time required for analysis; ease of operation; management of disinfection byproducts; connection with present policies; existence of foreign and domestic application case studies; and correlation with water ecosystem.

The purpose of this study was to investigate the regional differences in food preference among college students participating in a nutrition education program via internet. The subjects were 1672 college students (male: 762, female: 910) and divided into 4 regional groups. A survey using a self-administered questionnaire was conducted using a self-administered questionnaire on taste and food preferences. Data was collected via internet or by mail. Prevalence of the food preferences among regional groups was examined using SPSS statistical package. Food preferences were significantly associated with sex and region. Female students in Chungcheong and Kyungsang areas showed significantly higher preference of the hot taste compared to Seoul and Kyunggi areas. Female students in Seoul, Kyunggi and Chungcheong areas showed significantly higher preference of the boiled bean rice compared to the Kyungsang area. The preference for Kimchi stew of female students in Seoul and Kyunggi was significantly higher than those in Chungcheong and Kyngsang areas. Male students in the Chungcheong area showed significantly higher Preferences of the Young radish kimchi, while female students in this area showed significantly higher preference of the Radish kimchi compared to other areas. The preference for roasted laver of female students in Seoul, Kyunggi and Kyungsang areas was significantly higher compared to the Chungcheong area. The preference for fried chicken of male students in Seoul was significantly higher than that in other areas. The preference for bean sprouts and season bonnet bellflower of male students in Seoul, Chungcheong and Kyungsang areas were significantly higher compared to the Kyunggi area. Therefore, these results Provide nation-wide information on food Preferences among Korean college students. (Korean J Community Nutrition 10(6) : $845\∼859$ 2005)

Objectives : The number of people in Mibyeong state that complain of physical and mental discomfort but without a clear medical diagnosis has rapidly increased, but the conventional medical system is insufficient to care for these people. By establishing an evaluation instrument for Mibyeong state, it will be possible to provide a research base for Mibyeong management system and expand the clinical area of integrative medicine. Methods : Mibyeong Index was designed to measure inconvenience and resilience of subject's complains including four physical symptoms (fatigue, pain, low sleep quality, indigestion) and mental distress include anxiety, anger, depression. A 21-item quality of healthy measure was developed and tested. We used results of a nation-wide stratified sampled adult data in Korea. Results and Conclusions : Mibyeong index had adequate internal consistency, Cronbach's alpha was 0.88 in general population(N=1,110). The correlation between establised quality of life questionnaires (including SF-12 and EQ-D5 VAS) and the Mibyeong index were from 0.468 to 0.493. The national promotion of advanced health for an aging society and original Mibyeong care technology based on traditional Korean medicine can be developed by a self-care system that enhancing health before suffering illness. We expect that this instrument could be contribute to health management of people in Mibyeong state.

Recommendaton: These are the highlights of the findings of the Timber Consumption Survey carried out by the Project in 1966, and covering consumption for the period from 1961 to 1965. The survey was oriented towards consumption for structural, commercial and industrial purposes and existing estimates for local (village-level) consumption as fuel and the like were adopted. A full report on the survey was submitted to the Bureau of Forestry in 1966. Long-term Trends: After allowance for anticipated population increase, this ten year's increase in industrial wood consumption represents a gain of about 30% in per capita consumption (from 0.0913 cu.m. per capita to 0.118 cu.m. per capita). This is only about half the expected general economic growth of about 75% (7% per annum). It is therefore likely (a) that the 1975 estimate is conservative, (b) that the consumption demand beyond 1975 may be expected to build up at a greatly increased rate. Estimated income elasticity coefficients are high, and with expected ir,creases in prosperity and population, the consumption is expected to rise to 10 million cu. meters by the year 2,000. Consumption Pattern: The breakdown of industrial consumption (1965) is given in Table 4-2, showing sawnwood consumption as the most important in 1965. The upward trend in all sectors over the 1961-65 period is expected to continue. The general consumption pattern is expected to change through 1975 with a sharp increase in the relative importance of pulp products (to 30% of total consumption) offset by declining relative importance of sawlogs. The following recommendations follow from the study: (i) Industrial forests. - A programme of establishment of consolidated industrial forests should be initiated as a matter of urgency. (ii) Fuelwood forests - Properly sited, protected and managed fuelwood forest, worked on a 20-year rotation, should be established as a nation wide basis. (iii) Hardwood utilization - Detailed investigations are required into the use of indigenous hardwoods for the pulp, particle board and hardboard industries. (iv) Mining timber - Preservation treatment of all mining timber should be enforced by law. (v) Sawmills - Licencing restrictions should be enforced to reduce the number of small, inefficient sawmills. b. Extension work should be undertaken bv government to improve sawmilling practices.

In this study, based on SSOP (Sanitation Standard Operating Procedure) for HACCP in Food Sanitation Act, essential facility, equipment and documentary records for HACCP implementation were identified. Usage and adoption of these devices at Korea Food ＆ Drug Administration appointed HACCP foodservices ("Appointed"), voluntary HACCP applying foodservices ("Voluntary applying") and HACCP non-applying foodservices ("Non-applying") have been compared. Total 46 contract foodservices were surveyed： 13 "Appointed" (65％ of nation-wide all appointed food services in February, 2002),17 "Voluntary applying" and 16 "Non-applying". For usage and adoption of facility and equipment, 18 out of total 27 surveying items showed significant differences at the three foodservice groups (p＜0.01 or p＜0.05). Specifically, following items showed lower usage than 70％ in the "Appointed"： ′A trench including grease trap′, ′3-compartment sink with hot water′. Regarding CCP monitoring tool installation, 8 out of total 9 items showed significant differences among the groups (p＜0.01 or p＜0.05). For the usage of 10 documentary recording items for HACCP application log, 7 items showed significant differences among the groups (p＜0.01 or p＜0.05). Resultantly, most of those essential facilities, equipment and documentary records ;were used only in the "Appointed". The limited usages of those were showed for the "Voluntary applying" where the dietitian answered they applied HACCP voluntarily. The "Non-applying" didn′t have many surveyed items.

Soil, ground water and sea bed are exposed to continuous accumulation of polluted materials causing serious environmental damage. It has been reported that such pollution causes a massive mortality of fish stock in rivers by the resuspension of toxic chemicals during strong wind conditions. Therefore, it becomes apparent that there is an immediate demand for the restoration treatment of polluted river bed (or sea bed) sediment layers. Pollution levels of major rivers and ports such as Pal-dang, Kyung-an rivers, Ma-san port are becoming public concern and are posing a serious environmental threat. In particular, the pollution of Shi-hwa river has become a nation wide issue for last few years. In spite of such public concern, the pollution level of such rivers or port are getting worse everyday. In this study, an environmentally sound engineering package is introduced which helps to restore the polluted river bed or sea bed sediments. This engineering package is consisted of a suction facility followed by a series of mechanical, chemical as well as biological treatment units. The suction facility is designed to minimize the secondary pollution due to the resuspension of toxic materials during suction. The sea bed cleaning engineering package is designed to be installed on the top of a floating barge. Such combination of environmental plant and shipbuilding technology provides a cost-effective solution, minimizing the cost involved in the transportation between suction and treatment facilities.

The aim is to analyze a performance evaluation of local governmental public hospitals. Data were collected from public disclosure system DB of National Tax Service on 15 July 2013. Twenty-two income statements of local governmental public hospitals were analyzed using descriptive statistic analysis. The analyzing factors were medical operating profit, contribution margin, and trend of operating profit. The important result was that the medical operating profit was negative, average medical operating profit was -4,678.9 million won. However, the contribution margin was positive in all local governmental public hospitals, and average contribution margin was 12,572.5 million won. The trend of operating profit was positive in 15 local governmental public hospitals between 2011 and 2012. The average increased operating profit was 1,299.1 million won. Through this result, we suggest that not only individual public health hospital perspective, but also the enterprise wide perspective like nation was significantly considered to make decision of closure or maintain of local governmental public hospitals.

The rural area has kept traditions and green open spaces highlighted in these days since the life quality elevated. Institute of Rural Resources Development has been conducting nation-wide survey project for rural amenity resources to construct the databases of rural amenity distribution and richness. Using surveyed data from the project, this study was implemented to evaluate rural amenity values based on SAW (Simple Additive Weighting) method considering two aspects including living and tourism amenity. For defining the set of evaluation criteria, the rural amenity resources were classified into almost intact nature resources(natural resources), interaction between nature and man resources(cultural resources) and man-made resources(social resources). The weighting values of the criteria were evaluated from the step wise pair-comparison results by AHP(Analytic Hierarchy Process) method. In the results of weighting values related to living amenity, social resources was the hightest ranked criterion (0.512), followed by cultural resources (0.245) and natural resources (0.243). On the other hand, the results related to tourism amenity was that weighting values of natural resources, cultural resources and social resources were 0.481, 0.340 and 0.179, respectively. The two aspects evaluation methods was applied to the selected 18 areas (Myeon administration level) in Chungcheongbuk Do. The results demonstrated the differences of amenity values for living conditions and tourism conditions and could be used for prioritizing rural amenity planning.
