Modified T trellis (MT) and Wakeman trellis (WT) were widely used Korean vineyard because they had an advantage for spur pruning type cultivar such as Campbell Early. In this experiment, we compared labor time and intensity for bunch management between MT and WT trellis systems in 'Campbell Early' grapes. As a result, berry thinning was required 17.3 hours (10a) on the WT trellis but was required 12.3 hours (10a) on the MT trellis. In like manner, bagging was required 10.1 hours (10a) on the WT trellis but was required 8.2 hours (10a) on the MT trellis. On the other hand, labor intensity measured on berry thinning and bagging practices using REBA (Rapid Entire Body Assessment) index, then WT trellis was scored 13.0, but MT trellis was scored 8.6. Meanwhile, MT trellis reduced vigorous growing of internodes length and width on grapevine shoots. Consequently, MT trellis is more convenience trellis for working ergonomically in Korea vineyard.

This study forecasts the outlook 10 years from now regarding domestic labor and caregiving by the Baby Boomer generation and the preparations needed in the context of the Fourth Industrial Revolution. The scenario-planning method was used to explore changing trends in domestic labor and caregiving, the rationale for which has been questioned by both seniors and family welfare experts. Based on the results of the survey and our researchers' opinions, it was concluded that the changing trends were caused by two factors: the probability of alterations in domestic labor and the strength of family relationships. On the basis of these conclusions, four scenarios regarding baby boomers' domestic labor and caregiving in 10 years were proposed using two axes: the "high and low probability of alterations" and the "strengthening and weakening of family relationships." The first scenario is a "preference for the self-caring form of family," which has a high probability of domestic labor alterations and weak family relationships. The second scenario is a "preference for the flexible form of family," which has a high probability of domestic labor alterations and strong family relationships. The third scenario is a "preference for the traditional form of family," which has a low probability of domestic labor alterations and strong family relationships. The fourth scenario is a "preference for the public caregiving form of family," which has a low probability of domestic labor alterations and weak family relationships. These results provide basic information about the various aspects of baby boomers' lives-including the development of various goods and services, the establishment of policies regarding seniors, and programs for successful aging-and can help equip our society to take the actions needed for a super-aged population.

This paper investigates how firms adjust wages, employment and hours in response to demand shifts. It focuses on rigidities and asymmetries in such adjustments. Major findings are as follows. First, wage adjustments are fairly small compared with worker adjustments. Second, wage adjustments are asymmetric with respect to sales growth: there is no responsiveness of wage growth when sales are declining, while adjustments are significantly positive when sales are rising. On the contrary, worker adjustments are symmetric with respect to demand shifts. Third, while workers are linearly adjusted to the sales growth, some nonlinearity is observed in the wage adjustment. Fourth, hours are generally nonresponsive to demand shocks. Finally, union firms cut wages rather than workers in the face of negative demand shocks.

Efficiencies of hand sorting, vermifuge application and combined methods of them for sampling earthworms in the field were compared. 1) hand sorting : sampling unit of soil (50 cm${\times}$50 cm${\times}$30 cm, width${\times}$length${\times}$depth) was dug out and earthworms were sorted by hands. 2) Vermifuge application : Solution of mustard, pepper or formalin was treated onto the soil surface of smpling unit (50 cm${\times}$50 cm, width${\times}$length). 3) Combined method : In a sampling unit of soil (50 cm${\times}$50 cm${\times}$30 cm, width${\times}$length), hand sorting was carried out into the depth of 10 cm or 15 cm and then vermifuge was treated. Earthworms were collected more in numbers by hand sorting than vermifuge application although it was much more time-consuming and labor intensive. Efficiency of mustard to extract earthworms was as same as formalin but much better than that of pepper. Combined method of hand sorting with mustard treatment was more efficient than vermifuge applications and other combined methods. And it could collect earthworms as many as hand sorting, but was much less time-consuming and labor-intensive than hand sorting. Thus combined method of hand sorting (to the depth of 15 cm) with mustard treatment could be recommended for the sampling of earthworms in the field.

This study reviewed the previous research materials and made a positive investigation to identify the structural interrelation of caddies' emotional labor, job stress and turnover intention. Some analytical findings are as follows: First, the job stress increases in proportion as the emotional labor. Second, the turnover intention is not in proportion as the frequency of emotional display or the subordinate element of the emotional labor but the degree of the emotional expression and dissonance. Third, the turnover intention is in proportion as the job stress. In other words, the higher the emotional labor, the more the job stress and turnover intention. Consequently, the caddies should be highly qualified to express themselves according to their job conditions. Also, the stronger the caddies' job stress, the more their turnover intention. It is necessary to use the leadership to relieve the job stress and motivate the caddies to have the pride. My solution will have a positive effect on lessening the job stress and turnover intention.

The purpose of this study was to analyze the structural relationship among emotional labor and work performance of information security professionals. To this end, we conducted a questionnaire survey on 176 security workers and analyzed the collected data using structural equation modeling (SEM). It was found that the frequency of emotional display was positively related to deep acting and surface acting. Also, the intensity and variety of emotional display was positively related to deep acting and surface acting. In addition, deep acting had a positive relationship with work performance and surface acting had an significantly positive relationship with work performance. The results of this study are meaningful to understand the influence of the emotional aspect of security workers on work performance. Therefore, the overall findings suggest that the training programs and education for the improvement of emotional labor capacity of deep acting are continuously required.

The purpose of this study is not only to explore the effects of emotional labor on job stress but also to investigate the moderating effects of grit and social support between emotional labor and job stress. A survey was conducted for 804 call center counselors in Daegu, Daejeon and Suwon to figure out research questions, and the collected data were analyzed with SPSS 25.0. The results of the data analysis are as follows. First, emotional labor of customer counselors was found to have a positive effect on job stress. Second, in the relationship between emotional labor and job stress of customer counselors, grit showed different results according to sub-factors. The higher the Perseverance of Effort, the higher the job stress, and the higher the Consistency of Interest, the lower the job stress. Third, in the relationship between emotional labor and job stress of customer counselors, supervisor support of social support had a moderating effect, while peer support had no moderating effect. It shows that in order to prevent job stress of customer counselors, who have a high intensity of emotional labor, it is necessary to intervene to help them develop a positive perception of themselves through non-cognitive factors such as grit and the support provided by a trusted target. In addition, appropriate intervention methods and educational environment should be supported.
