For the smooth implementation and success of smart city projects, it is necessary to recognize that there is a difference in the perception of value judgments or strategic goals among major stakeholders in the planning process. And it is necessary to aim the values and goals of smart cities through reconciliation of these differences. The two major stakeholders in the smart city development project are citizens group and government officials group. Government officials are in charge of establishing and implementing policies for smart city projects, and their value judgments and perceptions influence the policy direction. In these respects, government officials can be an important stakeholder group. Citizens are a group that includes ordinary residents and business owners who live in smart cities and are the ultimate users of infrastructure and facilities. This study investigated the importance perceptions of citizens and government officials, who are the major stakeholders, about the core values and strategic goals that the smart city project aims. Responses were collected using a structured questionnaire to which the AHP methodology was applied. And the priority of perceptions for constituent items was compared for each stakeholder group. Through the comparative analysis results, it was empirically confirmed that there is a difference in the values and goals pursued by the smart city project between stakeholder groups. As an empirical study on the stakeholders of the smart city project, this study is meaningful in contributing to the theoretical development in that it suggests that the conceptual structural model of the smart city strategy system presented in previous studies can be applied in practice.

우리나라 정원의 식물 이용 현황을 알아보고자 전국 36개 정원을 대상으로 정원식물을 조사하였다. 정원은 6가지 유형 으로 구분하였다. 그 결과, 36개소 정원에는 정원식물 712종 류가 식재되고 있었다. 교목, 관목, 초본의 비중은 평균 1:2:7 이었다. 개별 정원(10×10㎡)에서 교목은 평균 2.5종으로 12.6%, 관목은 4.1종 20.7%, 초본은 13.2종 66.7%를 차지했다. 식재 빈도 상위 5%에 40여 종이 포함되었으며, 맥문동, 일본조팝나 무, 수국, 회양목, 단풍나무, 옥잠화, 에키네시아, 산철쭉이 대 표적이었다. 양지형 정원에는 관목이 상대적으로 적고 초본이 많았으며 다른 유형보다 20~40% 이상 다양했다. 그늘형은 초 본보다 교목이 많았으며, 건조형 및 습지형과 마찬가지로 식 재 다양성이 20% 감소했다. 옥상정원의 도시형 정원은 초본 이 전체의 80~90%를 차지하고, 해안형 정원에는 목본과 초본 이 1:1로 목본 중심의 식재 특성을 보였다. 결과적으로 정원 유형에 따라 식재 다양성과 구성 비율이 명확한 차이를 나타 냈다.

This study identified single nucleotide polymorphisms (SNPs) that affect the body weight of chickens. Analysis of body weight showed that the Cornish breed had the highest body weight, and the Korean native chicken (Gray Brown) had the lowest body weight. TSH is composed of an α-subunit and a β-subunit, and the TSH-β gene encoding the β-subunit has been reported to be associated with obesity. In chickens, it is located on chromosome 26 and is reported to be associated with growth. The calcium-sensing receptor gene (CaSR) plays a role in the regulation of extracellular calcium homeostasis and is responsible for calcium absorption in the urinary tract, which affects the eggshell quality in poultry. It was shown that TSH-β was strongly correlated with weight in Cornish and Korean native (Gray Brown) chickens, particularly in those with the CC trait. However, CaSR showed no association with body weight in poultry; it was associated with calcium and the eggshell. Thus, selection for TSH-β can be used to produce individuals with more favorable traits in terms of body weight.

This study was conducted to compare differences in dietary habits and snack consumption behaviors according to level of job stress among 20- to 30-year-old office workers. Subjects were 205 office workers working in companies located in Seoul and the metropolitan area. Self-administered questionnaires written by the subjects were statistically analyzed by the SPSS 20.0 program. Subjects were classified into a high-risk job stress group (n=102, High-RSG) or low-risk job stress group (n=103, Low-RSG) by level of job stress. For dietary habits, the duration of meal time before suffering from job stress in High-RSG was significantly faster compared to Low-RSG. Appetite after suffering from job stress in High-RSG was significantly higher compared to Low-RSG. For snack consumption behaviors, the reason for snack intake was ‘job stress’ for 42.2% in High-RSG and ‘hunger’ for 31.1% in Low-RSG (p<0.05). Energy intake in the form of chocolates, castellacakesmuffins, and flavored milk during working hours was significantly higher in High-RSG compared to Low-RSG (p<0.05). Therefore, this study suggests that dietary guidelines to ameliorate job stress should be developed in order to manage and improve dietary habits caused by suffering from job stress among young office workers at companies.

The purpose of this study was to investigate and compare the consumption behaviors for purchase of Home Meal Replacement (HMR) products and importance and satisfaction on selective attributes of HMR in middle-aged adults by gender. The subjects were 919 middle-aged adults (400 males and 519 females; 40 to 64 years) residing in Seoul and its metropolitan area, who have HMR purchasing experience. The survey was conducted from January to August 2018. Statistical analysis was performed using SPSS 23.0 program. Consumption frequency of HMR products in male and female subjects was 1-2 times a month by 42.3% and 40.8% and 4-6 times a month by 26.8% and 19.8%, respectively (p<0.05). Reasons for purchasing HMR in male and female subjects were shown significantly different from saving time by 44.8% and 50.5% and easy cooking by 25.8% and 16.6%, respectively (p<0.01). HMR products with high preference and satisfaction for the subjects included Gimbap, precooked dried rice, and frozen food. According to the Importance-Performance Analysis (IPA), selective attributes of HMR with high importance and low satisfaction in the second quadrant were food additives, origin, nutrient content, and price, for both male and female subjects; additionally, hygiene was a factor included only by female subjects. Therefore, these results suggest that it is needed to consider to produce HMR products with improved qualities using reliable food materials and ingredients and to maintain competitive pricing for the expansion of HMR products consumption of middle-aged adults.

This paper is an exploratory study to investigate the influence of characteristics of local government web-sites on user satisfaction and trust. The objective of this research is to identify the characteristics of local government web-sites influencing on user satisfaction and trust, and determine how they affect user satisfaction and trust. From the literature review, we identify four characteristics which are expected to influence on user satisfaction: technical, information, customer-oriented, and work-performing characteristics. In addition, we develop research model that the four characteristics are expected to affect user satisfaction and trust via users’ perceived values. The results of the research are as follows. The technical, customer-oriented, and work-performing characteristics significantly affects perceived values, which significantly affected user satisfaction and trust. Perceived value is partially mediated by user satisfaction in affecting user trust. The characteristics of local government web-sites affecting perceived values differed partially by the purpose of visitor. As for the personal goal, the technical, customer-oriented, and work-performing characteristics significantly affect perceived values, with the technical and customer-oriented characteristics having more significant effects. As for the business goal, the technical, information, work-performing characteristics significantly affected perceived values, with information characteristics having more significant effects.

This study examined the effects of ‘Dietary education for children’s health UP’ (DECHUP) on the changes in knowledge, attitudes, and practice (KAP) of nutrition and food safety in 5th grade elementary school students in Incheon. The DECHUP program was conducted from May to October 2018 and consisted of education and activities focusing on the children’s levels of understanding. Data were collected before, immediately after, and 6 weeks after DECHUP using the same method. All data were analyzed using SPSS ver 20.0. The level of knowledge and attitudes of the subjects to nutrition and food safety was significantly higher after than before DECHUP, but the attitude of boys did not show any significant difference after 6 weeks. Although there were no significant differences in the behavior for nutrition in the practice of the subjects, there were significant positive changes in the behavior of food safety. The higher the satisfaction of DECHUP, the more positive the change in knowledge, and the more positive the attitude and practice behaviors. Therefore, DECHUP has positive effects on the KAP of the subjects, and it will be helpful for elementary school students to form desirable eating habits if it can be carried out periodically and continuously.

Azuki bean beetle (ABB), Callosobruchus chinensis (L.) is a field-to-storage pest of legumes and its female produces sex pheromone with two isomeric components, 2Z-homofarnesal and 2E-homofarnesal. Two day old virgin adults were exposed to 0, 200, 300, 400, 500 & 600 Gy gamma radiation and effect on longevity, fecundity, sterility and pheromone production were studied. Longevity (female; P < 0.001, male; P < 0.001) and fecundity (P < 0.001) were dose-dependently affected by the gamma irradiation. Both adults were totally sterilized by the tested doses of gamma irradiation as depicted by the null hatchability of laid eggs. Gas chromatography-mass spectrometry for solid phase micro extraction revealed that both of the pheromone components were significantly but not completely reduced by 300 Gy. It is a pre-requisite for a successful sterile insect technology that the sterility of ABB is induced without the total disruption of calling behavior.

Azuki bean beetle (ABB), Callosobruchus chinensis (L.) is a field-to-storage pest of legumes. It is ideal to estimate its field population before it invades the stored legume stuffs. The seasonal occurrence was monitored with rocket traps supplied with synthetic female sex pheromone and with sweep netting during 2015-2016. Harvest damage was evaluated by taking purposive samples of the pods at harvest. Over-wintering stage was identified from the pod samples of left over plants. The results ascertained that October was the peak season of ABB in the azuki bean field. Grain damage and weight loss of the harvested azuki bean were 2.7% and 2.4% respectively, which could be the inoculum for storage loss. The adult emergence only from live pupae collected from pods revealed for its most probable over-wintering stage. In all, this study provides insight into some field ecological parameters of ABB that could be helpful in adopting its management strategies.

Plant essential oils (EOs) exhibit an array of biological activities against insect pests. However, their negative influences on the pheromonal activity of azuki bean beetle (ABB), Callosobruchus chinensis L., the field-to-storage pest of legumes, have not received research attentions. We evaluated the effects of three EOs and their two major components on the attractiveness of male ABBS to synthetic homofarnesal (2E- : 2Z-homofarnesal = 6:4) using Y-tube olfactometry in laboratory and rocket traps in the semi-open vinyl house. The tested EOs of Illicium verum, Croton anisatum and Gaultheria fragrantissima as well as the major components, trans-anethole and methyl salicylate ascertained significant negative effect against homofarnesal both in Y-tube olfactometry and in semi-open vinyl house tracing out a new opportunity of integrating them in ABB management programs both in field and storage.

This study was conducted to investigate the nutrition knowledge, dietary attitudes, dietary behaviors, smartphone usagerelated dietary habits, and health-related lifestyles of higher grade students in elementary school according to risk level of smartphone overdependence. Subjects were 286 fifth and sixth grade students of elementary school in the Siheung and Ansan areas. Data were collected using self-administered questionnaires and analyzed using SPSS v. 20.0. Based on scores of S-scale (smartphone overdependence scale for adolescents), subjects who used smartphone were classified into an overdependence group (ODG, n=52) and a normal group (NG, n=234). The ODG showed a significantly longer usage time than NG on both weekdays and weekends (p<0.001). There were no significant differences in total scores of nutrition knowledge between the ODG and NG. Average total scores of dietary attitude and dietary behavior in the ODG were significantly lower than in the NG (p<0.001). There were higher risks of ODG for skipping meals (OR=8.3, 95% CI=4.027-17.099), changing eating speed (OR=4.4, 95% CI=2.209-8.822), and changing meal amount due to smartphone usage (OR=2.9 95% CI=1.233-6.623). Therefore, education programs are needed to ensure proper dietary behaviors and habits among smartphone overdependent elementary school students.

This study investigated the nutrition knowledge, dietary habits, and food intake frequency according to hospitalization after breast cancer surgery and experience of breast cancer among female adults residing in the Bucheon area. Subjects were 52 female breast cancer survivors 27 in the hospitalization group (HG) and 25 in the non-hospitalization group (non-HG)] and 52 controls. Data included the results of self-administered questionnaires, as well as anthropometric data and blood biochemical values of breast cancer survivors collected from electronic medical records. Statistical analysis was performed using SPSS 20.0 program. Nutrition knowledge and dietary habits revealed no significant differences between HG and non-HG, but intake frequency of root and tuber crops and kimchi was significantly higher in the HG group than the non-HG group (p<0.05). According to experience of breast cancer, total scores of nutrition knowledge among survivors (8.2) were significantly higher than those of the control group (6.3) (p<0.001). Fish and shellfish and fruit intake frequencies were significantly higher in the survivors group, whereas intake frequency of fast food, convenience food, and alcohol was significantly lower compared to the control group. Overall, these findings indicate it is necessary to develop and spread nutrition education guidelines to prevent the occurrence and recurrence of breast cancer.

The entomopathogenic fungus Metarhizium anisopliae B is a powerful biological control agent against Monochamusalternatus, a crucial mediator of the pinewood nematode Bursaphelenchus xylophilus. In this study, production of destruxins(dtxs), insecticidal cyclic hexadepsipeptides, was monitored in the submerged culture of M. anisopliae B. Three typesof dtxs, i.e., destruxin A, B, and E, were produced during the culture. Among the three dtxs, the production yield ofdestruxin A was best, followed by destruxin B and E. Destruxin A production was increased when pH was controlledat 6.0, whereas production of destruxin E was not affected by the pH control. The highest yield of dtxs A, B, and Ewere 16.4, 7.3, and 6.1 mg L-1, respectively. Considering that process for dtxs production has not been optimized, M.anisopliae B has more powerful implication as a biocontrol agent.

The entomopathogenic fungus Metarhizium anisopliae is one of potent biological control agents against a variety ofinsect pests. In this study, we investigated enzyme production of M. anisopliae strains A and B. They produced extracellularenzymes for degrading the epidermis of Monochamus alternatus, a crucial mediator of the pinewood nematode Bursaphelenchusxylophilus. With Q-TOF MS/MS analysis, 29 kDa protein, a major band on a SDS-PAGE gel, was identified as subtilisin-likeserine protease PR1A. M. anisopliae A produced an extracellular enzyme more efficiently than M. anisopliae B: however,enzyme activities targeted for the cuticle were comparable. Our results suggest that the two strains of M. anisopliae havethe biological potential against M. alternatus with insecticidal protease production.

Body scales directly exposed to external environments can be an important factor to understand various characteristics of a species such as habitat features, life history and basic ecology. In this study, we compared size and morphology of dorsal, outermost dorsal, keeled dorsal and ventral scales of total nine snake species in Korea; Oocatochus rufodorsatus, Elaphe dione, Rhabdophis tigrinus, Amphiesma vibakari, Dinodon rufozonatum, Hierophis spinalis in the Colubridae and Gloydius ussuriensis, G. brevicaudus, G. saxatilis in the Viperidae. The morphological characteristics of the scales seem to well reflect foraging modes and moving activity of both families. Uniquely D. rufozonatum had a diamond shape dorsal scale and had the greatest and smallest value of the ratio of width/length of dorsal and ventral scales, respectively. O. rufodorsatus, D. rufozonatum and H. spinalis did not have keeled dorsal scales and E. dione had keel on the few of dorsal scales. In addition, morphological characteristics of scales of three viper species were closely consistent with previously known phylogenetic relationships.
