Silvetia siliquosa is an ecologically and commercially important brown alga that is harvested from its natural habitats, but its population has recently been diminishing along the Korean coast. To develop new techniques for algal population restoration, we tested two newly developed transplantation methods (using polyethylene ropes and natural rock pieces) at two study sites, Gwanmaedo and Yeongsando, on the southwest coast of Korea, from May to November 2014. The transplants on polyethylene ropes showed significantly greater survival, maturity, and growth than those on natural rocks at both study sites. Newly recruited juveniles (<3 cm) of S. siliquosa increased remarkably from May to December near the transplants on polyethylene ropes and natural rocks.Therefore, we suggest that transplantation using polyethylene ropes is more effective than using natural rocks to restore the population of S. siliquosa in Korea.

Growth and reproduction of Palaemon serrifer were described and analyzed in a population inhabiting tide pools in warm temperate waters in Korea. The water temperature varied greatly in the tide pools, ranging from 8$^{\circ}C$ to 27.8$^{\circ}C$ Population structure and growth were investigated using size frequency distribution data collected from January to December 2003. Sex ratios fluctuated, but were almost equal during the breeding period. Growth was continuous and size increased gradually throughout the year. Adult females were larger and grew faster than males. von Bertalanffy growth parameters for a one-year sample of females and males were estimated as $L_{i\ddot{A}}$ = 11.32, K = 0.311, $t_0$ = -0.4115 and $L_{i\ddot{A}}$ = 8.36, K = 0.228, $t_0$ = -0.9693 respectively. Breeding was seasonal, starting in May, peaking in August, and finishing by the end of August. The species showed continuous production of successive broods. Laboratory observation showed that females with embryos near hatching had ovaries filled with vitellogenic oocytes ready for spawning. The reproductive output (effort) of each female (mean number of eggs: $552{\sim}1355$) was not high. The mean embryo volume, $0.078mm^3$, is relatively small, indicative of low energy allocation to each embryo. Recruitment of juveniles was closely linked to the breeding period, beginning in September.

In recent years, many firms have built a good recruitment policy, focusing on the requirements set for candidates to meet the employers' satisfaction; they often have certain requirements for each accounting job's position. The study aims to identify and measure factors affecting the employers' satisfaction with accounting graduates in Hanoi, the important locus of firms' labor force. We conducted a questionnaire consisting of 16 observation variables with a 5-point Likert scale. Independent variables were measured from 1 "without effect" to 5 "strongly". Based on the literature review and results of interviews, a total of 150 questionnaires were sent to participants; 135 of them met the standards and were subject to be analyzed. The results of Cronbach's alpha, Exploratory Factor Analysis (EFA) and Multiple Regression Analysis (MRA) identify three main determinants influencing the employers' satisfaction with accounting graduates in Hanoi, including students' experience before graduating (SEG), reputation of universities (RU), and university's recruitment support policy (RSP). Based on the findings, some recommendations have been proposed to help universities design training programs for creating better satisfactions for employers in the future. On this basis, the authors propose a number of recommendations to improve the employers' satisfaction with accounting graduates in Hanoi.

It is challenging to simultaneously estimate parameters in a stock-recruitment relationship, steepness, and natural mortality rate with the other parameters within an age-structured assessment model even in a data-rich situation. Such a problem leads to uncertainty in estimates of management references such as maximum sustainable yield (MSY), which are affected by those components. The objective of this study was to evaluate the effects of those parameters on MSY by analyzing the process of estimating the MSY. For illustration, we used two data sets: The chub mackerel Scomber japonicus in the Korean waters and the yellowtail flounder Limanda ferruginea in the Southern New England-Mid Atlantic. As a result, the natural mortality rate influenced spawning stock biomass per recruit, yield per recruit, and MSY, while steepness affected MSY. A sensitivity analysis enabled us to estimate the natural mortality rate and steepness. The optimal set of steepness and natural mortality was 1.0 and 0.37 per year for the chub mackerel, and 0.35, and 0.8 per year for the yellowtail flounder, respectively.

Despite the growing use of SNS and the increasing number of recruitment related to SNS, little research has been conducted between career preparation activities and relationship with SNS. Therefore, this study investigates the relationships among purpose of using instagram, flow of instagram and career preparation behavior using structural equation model, and by investigating the adjustment effect of the personal characteristic among them. To this end an online survey was conducted for students who want to be cabin crew. The results of this study show that motivation of using instagram had a positive and significant effect on flow of instagram, which in turn positively influenced career preparation behavior. Furthermore, it could be confirmed that there was a adjustment moderating effect on personal characteristic between purpose of using instagram and flow of using instagram. The results of this study suggest that the likelihood of recruitment for being cabin crew can be achieved by identifying mutual relationships among motivation of using instagram, flow of instagram, career preparation behavior, and personal characteristics.

This study explores how generative AI technology can be utilized to create more efficient and effective employment portfolios in the rapidly changing job market and recruitment landscape. To achieve this, the study first conducted an in-depth analysis of recent employment trends and recruitment patterns, categorizing various generative AI tools based on their application in areas such as resume writing, portfolio design, and video production. Particularly, this research includes a case study of a career planning course in a university setting, where generative AI was applied, to empirically evaluate its potential for educational use. Through this case study, the research thoroughly examines how generative AI can contribute to efficient job preparation and skill enhancement for job seekers. The findings suggest that generative AI plays a critical role in providing personalized information, generating creative ideas, and enhancing both the visual and functional quality of employment portfolios, ultimately contributing to increased competitiveness in the job market. The study also emphasizes the need for further research on the expanding scope and effectiveness of generative AI as the technology continues to evolve.

Asthma is an inflammatory airway disease and is characterized by the releases of inflammatory mediators including chemokines. They are mainly associated with the recruitment, activation and dysregulation of specific inflammatory cells, especially neutrophils in neutrophilic asthma. CC chemokines bind to CC chemokine receptors (CCRs) in the surface of their target cells. The aims of this study are to examine the CCR expression in neutrophils of bronchoalveolar lavage fluid (BALF) of asthmatic patients and to determine the alternation of migration and apoptosis of neutrophils by the BALF. We demonstrate that CCR3 strongly expresses in BALF neutrophils of asthmatic patients as compared to other CCRs and increases during apoptosis of the BALF neutrophils. The migration of asthmatic blood neutrophils increases in response to asthmatic BALF as compared to BALF of normal volunteer. In addition, asthmatic BALF includes the higher levels of IL-8 protein than normal BALF and it has no effect on apoptosis of asthmatic blood neutrophils. Taken together, our results indicate that CCR3 expression may be associated with unknown function of asthmatic BALF neutrophils and BALF may be involved in the recruitment of neutrophils into the airway, but not in the neutrophils apoptosis.
