One of the theoretically and empirically grounded black boxes in HRD and firm performance link is employee' attitudes such as organizational commitment and job satisfaction. However, most studies were conducted with the regression analysis at the organizational level. This study used HLM(hierarchical linear modeling) analysis, which made it possible to estimate more accurate relationship between variables that were measured from two different levels. In addition, this study attempted to open an the black box(learning culture) in the relationship between HRD and employee attitudes. The result showed that the HRD have a positive effect on the organizational commitment and the job satisfaction. Also the HRD showed full mediation effect of organization commitment and the job satisfaction on the Learning culture. And the result showed that the HRD in 2007 have a positive effect on employee' attitudes in 2009. These findings concluded that systematic HRD like employee's education and training must be built and also the positive culture for employee's learning like support of management's learning organization must be improved in order to promote the organizational performance(organizational commitment, job satisfaction) in company.

IEEE 802.11ay Wi-Fi is the next generation wireless technology and operates in mmWave band. It supports the MU-MIMO (Multiple User Multiple Input Multiple Output) transmission in which an AP (Access Point) can transmit multiple data streams simultaneously to multiple STAs (Stations). To this end, the AP should perform MU-MIMO beamforming training with the STAs. For efficient MU-MIMO beamforming training, it is important for the AP to estimate signal strength measured at each STA at which multiple beams are used simultaneously. Therefore, in the paper, we propose a deep learning-based link quality estimation scheme. Our proposed scheme estimates the signal strength with high accuracy by utilizing a deep learning model pre-trained for a certain indoor or outdoor propagation scenario. Specifically, to estimate the signal strength of the multiple concurrent beams, our scheme uses the signal strengths of the respective single beams, which can be obtained without additional signaling overhead, as the input of the deep learning model. For performance evaluation, we utilized a Q-D (Quasi-Deterministic) Channel Realization open source software and extensive channel measurement campaigns were conducted with NIST (National Institute of Standards and Technology) to implement the millimeter wave (mmWave) channel. Our simulation results demonstrate that our proposed scheme outperforms comparison schemes in terms of the accuracy of the signal strength estimation.

The practice of producing and transmitting TV programs with uneven loudness can harm audiences' welfare in the digital environment where audiences are entitled to be offered quality broadcasting service. The purpose of this paper is to investigate issues concerning the digital loudness policy institutionalized in Korea since May 2016, and to offer policy suggestions. This paper reviews previous studies on audience welfare in digital broadcasting, focusing on the close link between loudness policy and audience welfare. In order to explore the state of international policy, this paper examines loudness standards developed by international standardization organizations including ITU, ATSC, and EBU, along with loudness regulations in the US, the UK, Canada, Australia, Japan, and Korea, respectively. Based on the analysis, this paper suggests recommendations for policy makers and broadcasters. First, policies on mandating regular monitoring and establishing penality system should be established for broadcasters not to violate loudness standards. Second, broadcasters are recommended to collect audience feedback, to be equipped with loudness measuring devices, to offer personnel training programs, and to check the compliance of loudness standards when they outsource TV programs.

Objectives: This study identified factors impacting radiation knowledge among aircrew, who are affected by cosmic radiation exposure due to their occupational environment. Methods: In September 2019 we conducted an online survey of aircrew through a Google link. We evaluated the level of radiation knowledge using a ten-item (10 points) questionnaire. The following exploratory variables were evaluated in relationship with the level of radiation knowledge using univariable linear regression models: sex, age, duration of employment, position level, company, marriage, education level, personal/family history of disease, and the number of times acquiring information on radiation through various channels (internet searching, watching television, reading newspaper, conversation about radiation with aircrew/non-aircrew, in-house training). With a p of 0.2 in univariable models, we built a multivariable linear regression model using a stepwise selection method. Results: The average radiation knowledge score of the 356 respondents was 7.22. Univariable linear regression analysis showed that radiation knowledge of the aircrew was associated with their company, position level, age, and number of conversations with other aircrew members. Our multivariable model showed that the radiation knowledge level of aircrew decreased as they had more conversations about radiation with other aircrew members and as their age increased. Conclusions: Korean air crew showed a lower level of radiation knowledge as their age and the number of conversations with colleagues increased. The study suggests that more education is needed in order for aircrew to gain accurate radiation knowledge.

This paper describes on the real-time tracking of ship's dynamic behavior by AIS information in the coastal waters. The AIS data was received at a land station by using the antenna of AIS receiver mounted on the rooftop of the laboratory, Pukyong National University (PKNU), Busan, Korea, and stored as a NMEA format of serial output sentence of VDM(VHF Data-Link Message) and displayed on the ENC(Electronic Navigational Chart) of a PC-based ECDIS. In this study, the AIS receiver was mainly used to obtain the dynamic information that is necessary to evaluate and track the movement situation of training ship "KAYA" of PKNU in the coastal waters. The change of position with time for the ship turning under the rudder angle of port $30^{\circ}$ was correctly tracked with the turning circle of 940 m in diameter on the ENC of a PC-based ECDIS. Then, the dynamic information of the AIS system was updated every 6.29 seconds under the turning situation for the speed of 10.9 knots and every 21.65 seconds under the situation running at the speed of 11.05 knots on the straight line route of $155^{\circ}$, respectively. In case of AIS target tracking in the inshore zone behind large topographical obstructions, such as mountain and apartment buildings, the update rate of dynamic information was irregularly changed by the existence of land obstacles. However, the position tracking by AIS information under the situation existing no sea obstructions was achieved in real or near real-time and the instant presentation of course alternations for the ship was correctly monitored by using a PC-based ECDIS. From these results, we concluded that the PC-based ECDIS technology and methodology combined with the AIS information can be easily extended and applied to the surveillance and management for the fishing operation of fishing vessels in the coastal zone and in the EEZ fishing grounds.

GNTECH-ICEE, which this study seeks to investigate and evaluate, demonstrates a new system of training innovative engineers. An essential component of this operation is a Small Engineering Group (SEG) that links professors, students and industrial experts together, to study and apply different techniques in determining the processes and products that relate industrial sectors needs. As an education program, SEG also provides a right direction for educating students, and generates industry-university link based human resources. Through these efforts, GNTECH-ICEE has effectively trained creative, professional, and practical engineers, by operating a variety of programs for meeting industrial needs and enhancing engineering education. SEG has many merits that have influenced its success so far, but the program also faces some challenges. The merits include; strong group bondage, practical ability incubation, and efficient administrative support. In terms of demerits, it is evident that sufficient theoretical education and local small-middle size enterprises (SMEs)' sustainable participation cannot be warranted. Thus, we propose that initiative strategies have been helpful to maximize GNTECH-ICEE's goal of making students into multi-player engineer, but continuously financial and administrative strategies be put into place in order to guarantee SMEs' long-term devotion to the program, and to help create a sustainable network between students and the companies involved.

This study is an analysis on how current elementary teachers think about nutrition education, how they are teaching it, and problems that have occurred. The main purpose of this analysis was to deal with future problems in nutrition education by analyzing the present situation . The survey was done on 544 currently working elementary school teachers. from the 9 education departments within Seoul, 2 schools were chosen from each department by stratified random sampling. The survey used a questionnaire that was passed out personally to teachers from September 1, 1997 to the 19th. The 544 usable questionnaires were analyzed by using the teachers had nutrition education training and the average score of nutrition knowledge was 13.30 $\pm$2.73 out of 20. Nutrition education was being taught as apart of other subjects in 87.9% of the schools, and mainly by lecture. Audio visuals aids were used by 53.7% of the teachers and the most common was the VTR. Nutrition education was taught as a part of physical education and 41.5% were using teacher guides to help them. 91.9% of the teachers supported the idea of nutrition education in elementary schools. Nutrition education was supported by 80. 0% of teachers to begin when children are in kindergarten, proving that early nutrition education is supported. The analysis showed that nutrition education should be taught by parents(29.4%) , teachers(29.2%), and nutritionists(25.9%) relating that family , education, and school lunch programs should tie in with each other. 96.7% of the teachers responded that they would teach nutrition education. However, 41.0% disagreed with having a separate course for nutrition education . Proper eating habits, nutrition and its diseases, and growth with nutrition were the main categories within nutrition education and the most effect method was thought to have audio visuals, guides for teachers , and to link the subject matter with school lunch programs. The teachers main responses to problems with children were that they are too much instant food, did not eat in a variety , and had no manners in eating. Ironically, the believed that malnutrition, fainting and growth stunt were not important nutrition problems.

As animation industry continues to evolve in China, the demand for excellent manpower is on the increase. However, there is a difficulty in cultivating practical talents because many colleges and universities in China do not have the systematized animation education. This study compares the curriculum for animation major in Korea and China in order to find out the major problems and the improvement plans of animation education in China. It was shown that the curriculum in China mainly consisted of the subjects to learn technical skills and lacked the subjects to enhance students' creativity. Especially, universities in China did not offer the practice environment in which students apply and utilize what they learned. As a result, students had less opportunity to experience creative process of making animation. In order to solve these problems, it is necessary to make the balanced basic curriculum, link the practice courses with the creativity courses, develop the specialized learning methods and provide the training opportunities through industry-university cooperation. The results of this study suggest that good quality animation education is an important element for universities and animation industry to continue to prosper together.
