  • Objectives: Studies on the geographical differences in mortality tend to use a census population, rather than a registration population, as the denominator of mortality rates in South Korea. However, an administratively determined registration population would be the logical denominator, as the geographical areas for death certificates (numerator) have been determined by the administratively registered residence of the deceased, rather than the actual residence at the time of death. The purpose of this study was to examine the differences in the total number of a district population, and the associated district-specific mortality indicators, when two different measures as a population denominator (census and registration) were used. Methods: Population denominators were obtained from census and registration population data, and the numbers of deaths (numerators) were calculated from raw death certificate data. Sex- and 5-year age-specific numbers for the populations and deaths were used to compute sex- and age-standardized mortality rates (by direct standardization methods) and standardized mortality ratios (by indirect standardization methods). Bland-Altman tests were used to compare district populations and district-specific mortality indicators according to the two different population denominators. Results : In 1995, 9 of 232 (3.9%) districts were not included in the 95% confidence interval (CI) of the population differences. A total of 8 (3.4%) among 234 districts had large differences between their census and registration populations in 2000, which exceeded the 95% CI of the population differences. Most districts (13 of 17) exceeding the 95% CI were rural. The results of the sex- and age-standardized mortality rates showed 15 (6.5%) and 16 (6.8%) districts in 1995 and 2000, respectively, were not included in the 95% CI of the differences in their rates. In addition, the differences in the standardized mortality ratios using the two different population denominators were significantly greater among 14 districts in 1995 and 11 districts in 2002 than the 95% CI. Geographical variations in the mortality indicators, using a registration population, were greater than when using a census population. Conclusion: The use of census population denominators may provide biased geographical mortality indicators. The geographical mortality rates when using registration population denominators are logical, but do not necessarily represent the exact mortality rate of a certain district. The removal of districts with large differences between their census and registration populations or associated mortality indicators should be considered to monitor geographical mortality rates in South Korea.

  • Intraspecific variation in morphometry of pine wood nematodes Bursaphelenchus xylophilus and B. mucronatus in relation to geographical locations in South Korea was investigated using morphometric characters (body length, a, b and c ratio, stylet length, and spicule length for a male nematode and V (%) value for a female nematode). B. xylophilus was isolated from Pinus thunbergii in Jinju (1998), Ulsan (2000), Yangsan (2000), Mokpo (2001) and Jeju (2004), and from P. densiflora in Gumi (2001). B. mucronatus was isolated from P. thunbergii in Jinju (1991) and from P. densiflora in Milyang (2001). The body length of male and female B. xylophilus had the highest coefficient of variability and showed significant differences among geographical locations. The V (%) value for female B. xylophilus showed the lowest coefficient of variability, changing little with geographical area and host plant. All morphometric characters in B. mucronatus except for stylet length and female body length showed no significant differences between locations or hosts, suggesting they may not be affected by geographical area or host plant.

  • The purpose of this study was to investigate the characteristics of dining-out customers by their behaviors based on geographical regions and visiting days in relation to restaurant attraction at ski resorts in Korea. The data were collected from six ski resorts. Three of the ski resorts were located in Kyunggi Province close to a metropolitan area, namely Seoul. The other three resorts were located in Kangwon Province, which is considered to be distant from the Seoul metropolitan area. A total of 599 usable questionnaires were utilized in the data analysis. Descriptive statistics and a cross tabulation analysis with chi square were used to examine the demographic characteristics of the respondents and the significant differences between geographical regions as well as between weekdays and weekends. The responding customers consisted of 57.3% (n=343) males and 42.7% (n=256) females. With respect to age, 15.5% were less than 20 yr., 44.6% were $20{\sim}30$ yr., and 28.0% were $30{\sim}40$ yr. The most recognizable occupations were student (32.9%) followed by office worker (33.2%). Twenty-seven percent of the respondents had less than one year of skiing experience and the majority (32.9%) had more than $1{\sim}3$ yr of experience. The major findings obtained from this study include statistically significant differences in the customers' demographical characteristics of age, occupation, skiing experience, and residential area according to the geographical regions of Kyunggi Province and Kangwon Province (p<0.05). All six of the customers' behavioral attributes, including transportation, reason to visit, staying days, purpose of visit, spending expenses, and usage of discount programs, showed significant differences between geographical groups (p<0.05). Finally, restaurant attraction was associated with the purpose of visiting and spending expenses by customers at the ski resorts (p<0.001).

  • This study was conducted to identify the differences in service quality between Incheon and Kimpo international airports and critical factors influencing satisfaction of their customers. According to the results of the study, all service quality factors of Incheon international airport except the service factor of geographical location were better than those of Kimpo international airport. However, all service quality factors of the two airports were evaluated inferior to those of American, western European and Japanese international airports. In addition the service quality factors such as response, safety, airport facility and geographical location were found as critical factors influencing satisfaction of the airport customers. The service quality factor of geographical location of Incheon international airport was measured much inferior comparing with other service quality factors. Thus, the results of this study suggest that the Korean government deliberate and benchmark the international airports of western Europe and the USA in determining the geographical location when planning new international airports.

  • Physiological and morphological differences in larvae and female adults of Thecodiplosis Japonensis from Haenam, Chullanamdo, and Chunsung, Kangweondo, were studied by means of electrophoretic technique and scanning electron microscope (SEM). On zymograms of whole body, third instar larvae of T. japonensis showed geographic differences in the band patterns of esterase and MDH iszymes, but patterns and the staining density of general proteins were similar in tow populations. In female adults, the populations revealed geographic differences in general proteins and esterase isozymens. In external ultrastructures, especially in genital segments, each population had distinctive structures in the 2nd segment of ovipositor.

  • This study was conducted a comparative study to identify the differences in service quality between Incheon and Kimpo international Airport and critical factors influencing satisfaction of airport customers. According the results of this study, all service quality factors except the service factor of geographical location of Incheon international airport are better than those of Kimpo international airport. However, all of service quality factors of Incheon airport are evaluated as inferior to those of american, western european and japanese international airports by both the airport visitors and the employees of one korean airliner. In addition the service factors such as response, safety, airport facility and geographical location are found as critical factors influencing satisfaction of the airport visitors and the airliner's employees. Among them the service quality factor of geographical location of Incheon airport is much inferior to that of Kimpo airport comparing with other service quality factors. Thus, the results of this study suggest that the managing team implement TQM and six sigma to enhance the service quality level of the Incheon international airport up to that of the american and western european international airport. Especially, it is strongly required that the Korean governmen deliberate in deciding the geographical location in case of planning new international airport because geographical location is related to not only traffic to airport but also safety of landing, taking off and flying.

  • The main objective of this study was to develop a basic information base on Chinese consumers related to clothing purchases. Previous studies on Chinese consumers were extensively reviewed and in-depth interviews were conducted with 12 middle-level managers at Korean apparel companies which market their merchandises in China. Combined results from the reviews on previous studies and interviews indicated that traditional values, communism and industrialization are the major forces which shape contemporary Chinese consumers. Industrialization, in particular, accompanied by influx of western culture and economic development, has resulted in wide-spread phenomenon of conspicuous consumption. Thus, brand and brand images appeared to be the most important considerations for purchasing imported apparels. In addition, diversity of Chinese consumers and geographical differences were emphasized, which indicated need for market segmentation. Other characteristics including body measurements also provided implications for fashion marketing in China.

  • Cornus officinalis (Cornaceae) is primarily grown in Asian countries. The pericarp of C. officinalis (Corni Fructus) is a well-known traditional medicine with tonic, analgesic, and diuretic properties. We analyzed methanolic extracts of Corni Fructus (grown in Korea and China) by $^1H$ NMR spectroscopy. Metabolite profiling was performed to characterize the metabolic difference between different Corni Fructus origins (Korea or China). Principal components analysis revealed significant separation between Comus Fructus from different origins. The metabolites responsible for differences were identified using loading plots, coefficients plots, and variable influence on projection followed by t-tests. As a result, 16 metabolites were identified and quantified; tyrosine, acetate, sucrose, and malate differed the most between origins. These data suggest that NMR-based metabolomics can be used to identify differences between Corni Fructus samples obtained from different regions.

  • This study focused on the geographical concepts development and its zone of proximal development(ZPD) through the collaborative interaction. Among the conclusions are: 1) Students who have higher cognitive structure represented the Creator Seoul Metropolitan Area(GSMA) as a geographical concepts, not as a spontaneous concepts. The concepts is developed from concrete facts, subordinate element concept to basic element concept hierarchically. The most difficult concept that the learner should internalize was represented as the basic element concept. 2) Although ZPD of GSMA is individualized, it could be divided into 9 types. The ZPD was developed differently according to the qualitative differences how much more and how systematically represented the geographical concepts. The characteristics shown in this development procedure was that there was a quality change based on quantity extensive.

  • It is increasingly clear that student mastery of concepts and skills in geographic education is based on a complex set of variables. Sex and gender are the key variables. Much has been written about biological sex differences in learning, but less attention has been paid to the impacts of socio-cultural gender on learning geography. As such, the aims of this paper are two-fold. First, to examine theories which seek to explain why males and females might differ in their geographic and spatial knowledge or skill. Second, to examine the extent of sex differences and gender traits in the geographic learning. The results of study illustrate clearly that there are more similarities than differences between the sexes. Therefore, there are significant gender differences between the preferences of regions, contents, activities in the secondary geographic learning. The results also provide insights into improving contents and method of geographic education.
