Purpose - The purpose of this paper is to improve last mile delivery capability and ensure customers' satisfaction by approaching an analytic hierarchy process(AHP) and identifying criteria framework to determine locations of last mile delivery centre(LMDC). Research design, data, and methodology - Traffic congestion and emission policy in cities are barriers of last mile delivery in dense areas. The urban consolidation centre(UCC) cannot increase last mile delivery efficiency in dense cities because of their space and traffic limitation. In this paper, we develop a case to improve last mile delivery efficiency and to ensure customers' satisfaction by concentrating on LMDC. In addition, AHP has been applied to identify criteria framework and determine LMDC locations. The weighted priorities are derived from parcel delivery industry experts and have been calculated using Expert Choice software. Results - The framework criteria have assisted decision makers to place LMDC in a dense area to enhance customer's satisfaction with last mile delivery service. Conclusions - AHP has provided ranking framework criteria of LMDC potential for parcel delivery industry. The LMDC helps by improving last mile delivery efficiency to final destination amids conditions of CO₂ emissions, traffic congestion, and pollution problems. It especially concerns delivery service activities when delivering parcels to customers rather than UCC.

This study was accomplished to investigate the prevalence of obesity and the factors related to obesity of high school girls in the large cities from May 20 to July 10 1990. In this study, three hundred eighty nine high school girls were chosen from high schools located in Seoul and Inchon. Anthropometry including weight, height, and skinfold thickness (triceps) were measured, and dietary intakes were calculated according to food composition tables. Means of the obesity index, food pattern, nutrients intakes were compared by Pearson's correlation coefficient. Nutrient intakes of the groups categorized by tricep skinfold thickness were compared by means of Duncan's multiple range test. Prevalence of obesity was 16.7%, 3.6%, and 20.8% by criteria of skinflod thickness, BMI, and Rohrer Index, respectively. Most of the subjects had three meals and took snacks two times per day 23.9% of the subjects were taking nutrient supplements of which vitamin supplement was the most popular. Food habit of subjects such as frequency of snack and bedtime meal were positively related to fatness. Nutrient intakes of the obese groups classified by tricep skinfold thickness, tended to consume more calories than another tricep category groups. Therefore, it could be concluded that prevalence of obesity in this subject was higher than the one for the past years, and it was more profound in girls who had a poor food habits and high calorie intakes. Thus, these results suggested that a good food habits and adequate nutrient intakes are essential to prevent the obesity of high school girls.

Use of the viamin-mineral supplements markedly increased with the awareness of diet and health. Data were collected from the self-administered questionnaire of 450 free living elderly, 60 to 94 years old, in Korea, to assess the relationships between socioeconomic variables, beliefs about nutrition, and the factors affecting gupplements usage. In addition, vitamin-mineral intakes through the supplements were calculated, and compared with RDA. 44.9% of the subjects took the vitamin-mineral supplements, and significantly higher percentage of women(49.3%) than men(38.1%) took supplements(p<0.05). The higher the education level, monthly pocket money, the percentage of supplements consumption was higher. People living in large cities took more supplements than those in small cities. One of the mainly cited reasons for taking supplements was to maintain health. The most favored nutrient supplements used by the subjects were in the order of vitamin B complex, vitamin E and Calcium, and vitamin-mineral intake through the supplements were much greater than RDA and ranges of their intakes were very wide. Vitamin B1 and vitamin E were observed to consume excessive amount(63 times of RDA and 40 times of RDA, respectively). The reasons for supplementation were often inappropriate and unreliable sources of information were used. Thus nutritional understanding and education of the elderly peopled are needed in regard to the use of vitamin-mineral supplements, and the relationship between adequate diet and good health.

This study investigates the factors that affect China's air pollution using city-level panel data and spatial econometric models. We address three air pollutants ($PM_{10}$, $SO_2$, and $NO_2$) present in 30 cities in China between 2004-2012 using global OLS and spatial models. To develop the spatial econometric analysis, we create a spatial weights matrix to define spatial patterns based on two neighborhood criteria - the queen contiguity and k nearest neighbors. The results show that the estimated coefficients are relatively consistent across different spatial weight criteria. The OLS models indicate that the effect of green spaces is statistically significant in decreasing the concentrations of all air pollutants. In the $PM_{10}$ and $SO_2$ analyses, the OLS models find that the number of buses and population density are also positively related to a reduction in the concentration of air pollutants. In addition, an increase in the temperature and the presence of secondary industries increase $SO_2$ and $NO_2$ concentrations, respectively. All spatial models capture a positive and significant effect of green spaces on reducing the concentration of each air pollutant. Our results suggest that green spaces in cities should receive priority consideration in local planning aimed at sustainable development. Furthermore, policymakers need to be able to discern the differences among pollutants when establishing environmental policies.

Tourism content is one of the most important tourism resources in the regions and cities. also it is generally that is close with the regional identity. Currently our country case, it is true that tourism products and festival which consisted of same or similar ones are produced and held. But, we do not recognized that tourism contents applied same or similar ones are all representative tourism resources in the regions and cities. This paper thus analyzes the regional comparison between gangneung and paju using yul-gok as tourism contents and indicates their relation and a historical process of development for appling tourism contents in each region. For the aim of this study, the comparative analytic method of this study is divided four parts-tangible cultural properties, cultural events and festival, tourism policy, tourism information.

The concentrations of sulfur dioxide ($SO_{2}$) were measured from seven major cities and nine provinces in Korea for the period covering 1998 to 2003. Its concentration data were analyzed to explore the possible influences of spatial and temporal factors on the $SO_{2}$ distribution characteristics. Examination of spatial trends of $SO_{2}$ distribution and behavior indicated several interesting features. Although its annual trends appeared to be affected by the changes in the surrounding environmental conditions (e.g., regulation on the use of S-containing fuels), the seasonal trends indicated a cyclic and systematic pattern that may be characterized as: a gradual decrease in concentrations across winter, spring, fall, and summer. The results showed the generally enhanced mean concentrations of $SO_{2}$ from Ulsan, Busan, and Daegu with 12.8, 10.1, and 8.80 ppb, respectively. On the other hand, notably reduced $SO_{2}$ concentrations were seen from Gwangju and Jeju sites with its mean values of 5.43 and 3.88 ppb, respectively. The overall results of our study indicate that a decrease in $SO_{2}$ concentration levels continued through time, while its spatial distribution appears to be affected most sensitively by such factor as city scale and industrial activities.

Purpose - It is important to figure out the relationship between tourism carbon emissions and tourism economics for a healthy tourism development. Research design, data, and methodology - Data of this study are collected from 27 provinces (cities) of China. Tourist consumption stripping coefficient is used to calculate tourism carbon emissions. SBM-Undesirable model is used to measure the efficiency of tourism economics under the constraint of tourism carbon emissions. Results - The results show that: during the year of 2005-2015, there are obvious differences in totals and intensities of tourism carbon emissions among 27 provinces and cities which can be divided into three areas. There is a high possibility of underestimating the actual efficiency of tourism economics by leaving tourism carbon emissions out of account, and a high inefficiency caused by tourism carbon emissions will lead a low efficiency of tourism economics. Conclusions - The development of tourism should give consideration to both economic and environmental benefits, and reduce the inefficiency caused by tourism carbon emissions to improve efficiency of tourism economics by improving the level of technical efficiency and promoting technological progress.
