The rising prevalence of obesity and diabetes is a significant health concern both in globally and is now regarded as a worldwide epidemic. Added sugars like sucrose and high-fructose corn syrup (HFCS) are a major concern due to their link with an increased incidence of diet-induced obesity and diabetes. The purpose of this review is to provide insight into the effects of natural sweeteners as alternatives to sucrose and HFCS, which are known to have negative impacts on metabolic diseases and to promote further research on sugar consumption with a focus on improving metabolic health. The collective evidences suggest that natural alternative sweeteners have positive impacts on various markers associated with obesity and diabetes, including body weight gain, hepatic fat accumulation, abnormal blood glucose or lipid homeostasis, and insulin resistance. Taken together, natural alternative sweeteners can be useful substitutes to decrease the risk of obesity and diabetes compared with sucrose and HFCS.

Online reviews play a significant role in consumer purchase decisions on e-commerce platforms. To address information overload in the context of online reviews, factors that drive review helpfulness have received considerable attention from scholars and practitioners. The purpose of this study is to explore the differential effects of discrete emotions (anger, disgust, fear, joy, sadness, and surprise) on perceived review helpfulness, drawing on cognitive appraisal theory of emotion and expectation-confirmation theory. Emotions embedded in 56,157 hotel reviews collected from TripAdvisor.com were extracted based on a transfer learning model to measure emotion variables as an alternative to dictionary-based methods adopted in previous research. We found that anger and fear have positive impacts on review helpfulness, while disgust and joy exert negative impacts. Moreover, hotel star-classification significantly moderates the relationships between several emotions (disgust, fear, and joy) and perceived review helpfulness. Our results extend the understanding of review assessment and have managerial implications for hotel managers and e-commerce vendors.

Purpose: We evaluated the clinicopathological charicterics and prognostic impacts of lymphatic vessel invasion in gastric cancer without lymph node involvement. Materials and Methods: Among 1,795 patients who underwent gastric surgery with gastric cancer at the department of surgery, Hanyang university college of medicine from June 1992 to March 2009, we retrospectively evaluated 890 patients with lymph node negative gastric cancer. Results: The lymphatic vessel invasion correlated significantly with tumor stage, age, tumor size, perineural invasion and operation method. The survival rates were only significantly different between the patients with and without lymphatic vessel invasion in patients with stage Ia (P=0.036). Univariate and multivariate analysis demonstrated that blood vessel invasion and preoperative serum CEA level were significant factor influencing the survival rate in lymph node negative gastric cancer patients with lymphatic invasion. Conclusions: In patients with lymph node negative gastric cancer, the survival rate is significantly lower in those with lymphatic vessel invasion than in those without. Especially, in patients with stage Ia gastric cancer, the survival rates is significantly different between those with and those without lymphatic vessel invasion. Blood vessel invasion and preoperative serum CEA level is an adverse prognostic indicator in patients with stage Ia gastric cancer with lymphatic invasion. Thus we should consider further adjuvant therapies in case of need and need to show more concern to identify gastric cancer patients early at risk for recurrence.

Purpose - This study examined the influence relationships between the impacts of tourism development, local attachment, and resident involvement and local residents' support and pro-environmental behavior intentions in Jeju Island. Design/methodology/approach - A questionnaire was distributed to the Jeju Island residents and 373 samples were used for the analysis. Findings - The results showed that the perceived positive impact of tourism development has a positive effect on local residents' support, while the negative impact has a negative effect. Local attachment has no significant effect on local residents' support, while local involvement positively affects local residents' support. The positive impact of tourism development has a negative effect on pro-environmental behavior intention, while the perceived negative impact has a positive effect. Finally, when analyzing the relationship between local attachment, local involvement, and local support for eco-friendly behavior intention, it was found that they all have a positive effect. Research implications or Originality - Theoretical and managerial implications and suggestions for future research are discussed.

본고에서는 글로벌 금융위기의 충격을 산출량에 장기적 중립성을 가지는 근원적 충격과 장기적 중립성을 가지지 않는 비근원적 충격으로 나누어 글로벌 금융위기 기간 중 근원적 충격이 물가안정목표 달성에 미친 영향을 분석하였다. 본고에서 보인 바와 같이 글로벌 금융위기가 수요에 미친 영향과 이로 인해 물가가 안정된 효과를 제대로 파악하지 못하면 향후 물가안정이 어려워질 수 있다. 농산물과 석유류 제품의 일시적 공급충격을 제거한 통상적 근원인플레이션을 기준으로 평가하면, 2007~09년 중 물가안정목표는 안정적으로 달성된 것처럼 보이고 향후 목표 달성도 무난해 보인다. 그러나 중앙은행의 통제 대상인 구조적 근원인플레이션을 기준으로 평가하면 매우 달라진다. 글로벌 금융위기를 전후한 수요충격으로 근원인플레이션이 크게 변동하였으며, 2007~09년 중 물가안정목표 달성은 글로벌 금융위기에 따른 마이너스 성장에 기인한 바가 크다. 또한 글로벌 금융위기 이후 각종 경기확대정책에 힘입어 경기가 빠르게 회복되면서 근원인플레이션이 급격하게 상승하고 있으므로 향후 적절한 출구전략을 마련해야 한다.

Oceanic islands are biologically important for their unique assemblages of species and high levels of endemism and are sensitive to environmental change because of their isolation and small species source pools. Habitat destruction caused by human landscape development is generally accepted as the main cause of extinction on islands, with exotic species invasion a secondary cause of extinction, especially on tropical islands. However, secondary impacts of human development (e.g., general degradation through resource use and exotic species introduction) are understudied on temperate islands. To determine secondary impacts of human development on the understory vegetation community, 90 field sites on Ulleung Island, South Korea, were sampled during the summer of 2016. Understory vegetation was chosen as it is a proxy for ecosystem health. Diversity and percent cover of introduced, native, and endemic species were tested against proximity to developed areas and trail usage using a model selection approach. Diversity was also tested against percent cover of three naturalized species commonly found in survey plots. The main finding was that distance to development, distance to town, and trail usage have limited negative impacts on the understory vegetation community within best-supported models predicting native and introduced cover and diversity. However, endemic species cover was significantly lower on high usage trails. While there are no apparent locally invasive plant species on the island at the time of this study, percent cover of Robinia pseudoacacia, a naturalized tree species, negatively correlated with plot diversity. These findings indicate that forests on Ulleung Island are not experiencing a noticeable invasion of understory vegetation, and conservation efforts can be best spent preventing future invasions.

The aim of this study is to apply the Water-Energy-Food-Land Nexus approach which can analyze the trade-offs among resources, and assess the holistic impacts of food security. First, we applied rice as a study crop and analyzed the trend of consumption of rice and the area of paddy fields. Second, the portfolios of water, energy, and land for rice production were constructed using data of footprints and productivity. Finally, the self-sufficiency ratio (SSR) of rice in target year was set as food security scenario and assessed the impacts of food security on water, energy, and land availability. In 2030, the SSR of rice decreased to 87 %, and water use for producing rice decreased from 4,728 to $3,350million\;m^3$, and the water availability index increased from 0.33 to 0.53. However, food security is essential issue and we set the 50 % and 100 % SSR of rice as high and low food security scenarios. For 100% SSR in 2030, about $3,508million\;m^3$ water was required and water availability index reached to 0.5. In other words, there is the trade-off between food security and water-energy-lands availability. Therefore, it is difficult to make a decision whether a high level of SSR is better or worse. However, this study showed the both positive and negative impacts by change of food security and it can be useful for setting the policy decision considering both food security and sustainable resource management at the same time.

This study was conducted to explore the impacts of involvement in the Vietnam War on the self-esteem of the veterans in their later lives. In this study, 14 Korean male Vietnam War veterans from 55 to 63 years old were asked about the impacts of their war experiences on their self-esteem. From the analysis of the in-depth interviews the following conclusions were drawn: First, the veterans perceived that their self-esteem improved with both internal and external impacts of their activities in Vietnam. The internal aspects that improved the veterans' self-esteem were recalling their positive memories of Vietnam War, such as being on duty at a war front for the sake of our country, doing volunteer work for the villagers, and becoming a masculine heroic figure in the family legend. The external aspects were positive attitudes and responses toward their war activities from their family, friends, and neighbors. Second, they also felt persistently frustrated with their recurring memories of involvement in killing human beings, experiences of negative family and social responses, and the side effects of herbicidal cyanide they suffer. In this article, the following suggestions were made. First, standardized images and good-will episodes of the Vietnam War need to be provided by the government, in order to improve public images on the veterans. Second, intensive adjustment programs for the families of older veterans in special needs should be developed in collaboration with various veterans' societies and family counseling institutions, so that the spouses and children can be relieved from tension-laden contacts with the veterans and prevent violent incidents.
