Anticipatory postural adjustments are pre-planned by the central nervous system (CNS) before the activation of agonist muscles in the limbs, and minimize postural sway. Most previous studies on this topic have focused on upper-limb movement, and little research has been conducted on lower-limb movement. The purpose of this study was to investigate the recruitment order of left and right trunk muscles during limb movement. Fifteen healthy subjects (10 male, 5 female) were enrolled. Electro-myographic signals were recorded on the muscles of: (1) deltoid, lumbar erector spinae, latissimus dorsi and internal oblique during shoulder flexion, (2) rectus femoris, rectus abdominis, external oblique and internal oblique during hip flexion. During right upper limb flexion, the onset of left erector spinae muscle and left internal oblique muscle activity preceded the onset of right deltoid by 8.09 ms and 19.83 ms, respectively. But these differences were not significant (p>.05). A similar sequence of activation occurred with lower limb flexion. The onset of left internal oblique muscle activity preceded the onset of right rectus femoris muscle by 28.29 ms (p<.05). The onset of right internal oblique muscle activity preceded the onset of left rectus femoris muscles by 23.24 ms (p<.05). The internal oblique muscle was the first activated during limb movement. Our study established the recruitment order of trunk muscles during limb movement, and explained the postural control strategy of the trunk muscles in healthy people. We expect that this study will be used to evaluate patients with an asymmetric recruitment order of muscle activation due to impaired CNS.

Given the rise in international tourism and the rapid growth of the Vietnamese economy, the hospitality industry in Ho Chi Minh City, Vietnam's commercial hub, has been facing severe labor shortages due to competition with other fast-growing parts of the economy. These struggles to acquire high-quality employees is strangling future growth and placing new importance on the role of recruitment. To better understand the effectiveness of an organization's recruitment strategy, recruiters need to ascertain the Job Pursuit Intention (JPI) of job seekers to efficiently align an applicant's work notions with the organization's goals. This study aims to investigate the factors impacting on JPI among employees working in the hotel sector in Ho Chi Minh City. Secondary data are from previous studies and primary data are from consultation with 10 experts, group discussions and five in-depths structured interviews with 15 random employees and 302 survey questionnaires with employees working in three five-star hotels. Cronbach's Alpha, EFA, T-Test, ANOVA are used for statistical analysis. The findings show that compensation, career advancement, and work-life balance affect JPI of job seekers, in which compensation is the most influential factor. Furthermore, recommendations for recruiters, further research and limitations of this study have been laid out.

This study analyzed tourists' intention at Gangcheon Mountain, Sunchang-gun for local tourism. The contents of study included impression, characteristics, specialized resources, development direction, intention of visit and its form, destination prior and post visit, travelling expenses, and development form of tourism. The results were as following. Impression and characteristics showed that gochujang and fermentation industry established a strategic ground of local development. Intention of revisit of tourists was relatively high by 97.1%. Furthermore, tourists were mainly family units and they preferred family-based recreational type for the future local tourism development form. Therefore, a development strategy will be required that involves inexpensive accommodation, unique local food items, agricultural-specialty products and local tour packages. For invigoration of local tourism, recruitment of skilled managers for farm village experience will be necessary as well.

Marked declines in seagrass meadows are increasingly being reported from coasts around Korea and many regions of the world. The transplantation of seagrasses has been attempted to mitigate and control their degradation from a range of anthropogenic factors. In this study, Zostera marina shoots, which were collected from a donor bed in Koje Bay, were transplanted in Jindong Bay in December 2004. In 2008, a comparative investigation of shoot morphology, growth, and reproduction strategy of Z. marina was carried out between the donor and transplant sites to assess their adaptation success. Shoot height, individual shoot weight, and leaf productivity at the transplant site were significantly greater than those at the donor site. However, below-/aboveground tissue ratio was significantly lower at the transplant site compared to the donor site. Z. marina survival was maintained through vegetative reproduction, while peak season for lateral shoot recruitment was late winter for both donor and transplant site populations. However, vegetative reproduction mainly occurred during late winter and spring at the transplant site, whereas lateral shoots were evident across all seasons except late spring in the donor site. More pronounced seasonal variations were found at the transplant site compared to the donor site. These results indicate that Z. marina populations at the two sites possess distinct phenotypic variations induced by different environmental conditions, and Z. marina transplants have adapted well to the new transplant environment.

Purpose: According to current guidelines, perioperative chemotherapy is an integral part of the treatment strategy for advanced gastric cancer. Randomized controlled studies have been conducted in order to determine whether perioperative chemotherapy leads to improved R0 resection rates, fewer recurrences, and prolonged survival. The aim of our project was to critically appraise three major studies to establish whether perioperative chemotherapy for advanced, potentially resectable gastric cancer can be recommended on the basis of their findings. Materials and Methods: We analyzed the validity of the three most important studies (MAGIC, ACCORD, and EORTC) using a standardized questionnaire. Each study was evaluated for the study design, patient selection, randomization, changes in protocol, participating clinics, preoperative staging, chemotherapy, homogeneity of subjects, surgical quality, analysis of the results, and recruitment period. Results: All three studies had serious shortcomings with respect to patient selection, homogeneity of subjects, changes in protocol, surgical quality, and analysis of the results. The protocols of the MAGIC and ACCORD-studies were changed during the study period because of insufficient recruitment, such that carcinomas of the lower esophagus and the stomach were examined collectively. In neither the MAGIC study nor the ACCORD study did patients undergo adequate lymphadenectomy, and only about half of the patients in the chemotherapy group could undergo the treatment specified in the protocol. The EORTC study had insufficient statistical power. Conclusions: We concluded that none of the three studies was sufficiently robust to justify an unrestrained recommendation for perioperative chemotherapy in cases of advanced gastric cancer.

Background: The stem exclusion stage is a stage of forest development that is important for understanding the subsequent understory reinitiation stage and maturation stage during which horizontal heterogeneity is formed. Over the past 11 years (2009-2019), we observed a deciduous broad-leaved forest in the Albongbunji Basin in Ulleungdo, South Korea in its stem exclusion stage, where Fagus engleriana (Engler's beech) is the dominant species, thereby analyzing the changes in the structure (density and size distributions), function (biomass and species richness), and demographics. Results: The mean stem density data presented a bell-shaped curve with initially increasing, peaking, and subsequently decreasing trends in stem density over time, and the mean biomass data showed a sigmoidal pattern indicating that the rate of biomass accumulation slowed over time. Changes in the density and biomass of Fagus engleriana showed a similar trend to the changes in density and biomass at the community level, which is indicative of the strong influence of this species on the changing patterns of forest structure and function. Around 2015, a shift between recruitment and mortality rates was observed. Deterministic processes were the predominant cause of tree mortality in our study; however, soil deposition that began in 2017 in some of the quadrats resulted in an increase in the contribution of stochastic processes (15% in 2019) to tree mortality. The development of horizontal heterogeneity was observed in forest gaps. Conclusions: Our observations showed a dramatic shift between the recruitment and mortality rates in the stem exclusion stage, and that disturbance increases the uncertainty in forest development increases. The minor changes in species composition are likely linked to regional species pool and the limited role of the life-history strategy of species such as shade tolerance and habitat affinity. Our midterm records of ecological succession exhibited detailed demographic dynamics and contributed to the improvement of an ecological perspective in the stem exclusion stage.

Gyeongsangnam-do needed an employment stability response policy to induce re-employment of job seekers who retired due to large-scale unemployment and job instability following the employment crisis, and stable settlement and long-term employment after new employment.This study is to confirm the effective corporate support policy as an employment promotion strategy through new recruitment of the employment crisis in Gyeongsangnam-do. A total of 380 companies in Gyeongsangnam-do were targeted for the survey through online surveys and in-person surveys. As a result of the study, as a measure to improve working conditions through financial support for long-term employment stability, first, support for youth-middle-age asset formation of SME workers is required, and second, support for old-age income guarantee for SME workers was proposed. Third, direct corporate subsidies are continuously needed for job promotion and job stability of Gyeongsangnam-do companies.
