  • Cancer is a global public health issue that becomes the second primary cause of death globally. Considering the side effects of radio- or chemo-therapy, natural phytochemicals are promising alternatives for therapeutic interventions to alleviate the side effects and complications. Ginsenoside Rh2 (GRh2) is the main phytochemical extracted from Panax ginseng C.A. Meyer with anticancer activity. GRh2 could induce apoptosis and autophagy of cancer cells and inhibit proliferation, metastasis, invasion, and angiogenesis in vitro and in vivo. In addition, GRh2 could be used as an adjuvant to chemotherapeutics to enhance the anticancer effect and reverse the adverse effects. Here we summarized the understanding of the molecular mechanisms underlying the anticancer effects of GRh2 and proposed future directions to promote the development and application of GRh2.

  • This study was conducted to investigate effective ways to meet social and cultural interest in and needs of gardens and gardening. A total of 191 respondents who answered they were living in Gyeongnam region in the questionnaire were selected: 102 (53.4%) were males and 89 (46.6%) were females. In frequency of garden visits, 45% of the respondents answered they visited gardens once a year. Their preferred companion was family (43.6%), followed by friends/colleagues (24.3%). Their important motives of garden visits included admiration of gardens' scenery and ambience, pleasure in being outdoors, relaxing mentally and physically, and appreciation of plants. Relatively less important motives included understanding or educating about nature and environmental conservation, and interest in garden design and horticulture techniques. In the overall assessment of gardens and gardening, the quality of the establishment, management and operation of botanic gardens and arboreta in Gyeongnam region scored 3.32 scale, which was close to the level of 'fair.' Also, the respondents agreed at 3.91 scale that it was necessary to improve the garden creation, gardening, and garden culture. Meanwhile, many people in Gyeongnam region did not clearly understand differences between garden and public park, also had a very obscure perception of public garden. The results of importance-performance analysis (IPA) indicated that it is necessary to concentrate on directing and developing some programs such as admiration of beautiful and exotic plants, and education on garden culture including garden making and horticultural techniques.

  • The purpose of this study is to conceptualize PUST (Public understanding or science and technology) with a new theoretical perspective and to measure the Korean PUST through a national survey. Then, it suggests policy implications of improving the Korean public understanding of science and technology. Our new theoretical perspective is focused on an information receiver's one rather than an information provider's one. Thus, we concepualized PUST as a process of engagement: how a citizen becomes to be engaged to science or technology. It does not stress how hard s/he is pushed to learn science or technology. A national survey was done by a face-to-face interview method. About 1,200 adults were sampled from 18 or more years old population by a stratified area sampling method which had been used as a common and reliable one in South Korea. Each half of the total sample were for science or technology. The survey was conducted in September, 2001. We found that many Korean adults had positive but disproportionate impressions of science or technology that were related mostly to utilities for life such as computer, internet, car, refrigerator, television, etc. Most of them failed to continue to be engaged to sciences and technologies after first exposure to them through compulsory education. They were not able to relate sciences or technologies to solving individual or social salient problems. This study shows that PUST would be improved by our engagement to sciences or technologies through their relationship with social problems or issues.

  • As Korea enters into an aging society, the problem of information literacy against senior citizens is becoming a socioeconomic issue in Korea. Since most of the public libraries in Korea are already equipped with infrastructures for information dissemination, they may be able to solve this problem most effectively among public organizations. In this study in order to investigate senior citizen's general understanding of public library, cognizance of the programs for them. their information request levels, preferred contents, information seeking behavior, etc., 176 participants in educational programs at two senior citizens' welfare center were interviewed and surveyed with structured questionnaires. The statistical analysis of the surveyed data has shown that the senior citizen's general understanding of public library was very poor and that those under 75 years old preferred educational programs and those over 75 preferred recreational ones. Recommendations were made based on the results of the analysis.

  • Recent years, due to the direct or indirect damages caused by meteorological disasters more and more attention have been paid to natural disasters. At same time, diversified and multi-sensory interactive meteorological services is increasingly demanded. In this study, novel interactive meteorological service was compared with the traditional communication methods. Combining with case studies and systems creation, a virtual reality weather simulation framework was proposed, and a realistic virtual game environment providing real-time and historical weather information was created. The primary goal of this study is to build a weather display cabinet game system by using virtual reality technology, and promoting public's understanding of the principles of weather changes. With the interactive games in realistic scenarios, public's awareness for disasters prevention could be promoted. It is helping to change public's traditional understanding of meteorological theories, and will provide a more convenient way for the public to explore more effective weather forecasts. The simulation system is supported by VR technology. It was combined with Leap Motion interactive equipment to make popularization games for weather science. T-test data analysis showed that the application of VR technology in weather games has strong operability and interactivity.

  • Panax ginseng Meyer is a traditional Chinese medicine that is widely used as tonic in Asia. The main pharmacologically active components of ginseng are the dammarane-type ginsenosides, which have been shown to have anti-cancer, anti-inflammatory, immunoregulatory, neuroprotective, and metabolic regulatory activities. Moreover, some of ginsenosides (eg, Rh2 and Rg3) have been developed into nutraceuticals. However, the utilization of ginsenosides in clinic is restrictive due to poor permeability in cells and low bioavailability in human body. Obviously, the dammarane skeleton and glycosyls of ginsenosides are responsible for these limitations. Therefore, improving the oral bioavailability of ginsenosides has become a pressing issue. Here, based on the structures of ginsenosides, we summarized the understanding of the factors affecting the oral bioavailability of ginsenosides, introduced the methods to enhance the oral bioavailability and proposed the future perspectives on improving the oral bioavailability of ginsenosides.

  • Purpose: Public sector is usually not an attractive career choice for the youths, due to the uncompetitive income and the working environment. Therefore, understanding the motivations of the Generation Z, the currently early-career employees, to work in the public sector is important. This research aims to address a gap in the literature on the linkage between Personality Traits of Generation Z and Public Service Motivation (PSM). Research Design, Data, and Methodology: Using the sample of Vietnamese generation Z, it shows how individual personality, as defined by the Big Five, affects PSM. A quantitative survey of 355 university students, who are members of this generation and are preparing to join the labor market, was undertaken. We used SEM to examine the results. Results: Our findings show that Agreeableness, Neuroticism, and Conscientiousness are significant antecedents of PSM. Agreeableness, which leads to three PSM dimensions, namely Compassion, Self-Sacrifice, and Commitment to Public Values, is the best predictor of this motivation. Meanwhile, Neuroticism and Conscientiousness only affect the dimension of Compassion. Conclusion: This study adds to the limited current knowledge on the personality-PSM relationship among generation Z. The distribution of affective (Compassion, Self-Sacrifice) and norm-based (Commitment to Public Values) motives provide insight for both career counselors and recruiters in public service delivery.

  • A new radiation scale is proposed. With empathy toward the vast majority of people who are not well versed in radiation and related matters, and thus suffering from misunderstanding that breeds unnecessary fear of radiation, the aim of proposing a new radiation scale, radiation index (RAIN), is to put the general public at ease with the concept of radiation. RAIN is defined in dimensionless numbers that relate any specific radiation dose to a properly defined reference level. As RAIN is expressed in plain numbers without an attached scientific unit, the public will feel comfortable with its friendly look, which in turn should help them understand radiation dose levels easily and allay their anxieties about radiation. The expanded awareness and proper understanding of radiation will empower the public to feel that they are not hopeless victims of radiation. The correspondence between RAIN and the specific accumulated dose is established. The equivalence will allow RAIN to serve as a common language of communication for the general public with which they can converse with radiation experts to discuss matters related to radiation safety, radiation diagnosis and therapy, nuclear accidents, and other related matters. Such fruitful dialogues will ultimately enhance public acceptance of radiation and associated technologies.
