The United Kingdom has a well-developed and comprehensive information infrastructure which has grown up over many years, but in the strict sense it has no coherent body of policy relating to information collection, storage, provision and supply. However, each of the governmental, professional and other bodies which has any major involvement with information, has committees to run its affairs and develop its policies in relation to issues and problems in the field. In addition, a number of ad hoc committees and working parties, to discuss or deal with a current problem, or to monitor or advise on the conduct of a research or development project, show that there is a high degree of awareness. of what is happening in the field and that there are many opportunities for expressing any particular point of view. The need for good intelligence in business or industrial operations is now being more generally accepted, and in consequence the need for a director of intelligence is also seen. The director of information in an industrial setting is the information manager, who combines or has access to the skills of several disciplines, including library, data processing and communication skills as well as managerial. Recognition of the need for such persons has policy implications in terms of short-term training provision and long-term educational facilities for the emerging profession, as well as manpower planning implications.

This study provided an overview of how action learning runs in parents' education classes by analyzing the case of parent education program for prospective early childhood teachers. The subjects of this study were 32 pre - service teachers (30 students in early childhood education, 2 double major students) who were enrolled in the department of early childhood education at P university in Daejeon. The research was conducted theoretical and practical action learning program for 12 weeks. The data collection was organized by students preparing weekly diaries, group assignments, in-depth interview materials, colleagues and self-assessment, and analysed with the qualitative case study approach. The results of the qualitative analysis are as follows: Action learning teaching method provided opportunities to encounter diverse cases through student led and group activities. Students could experience a specific problem solving method between parents-children relationships as prospective parents. Students could have a chance to solve real-life situations that are difficult to experience in theoretical classroom situations between teachers-parents relationship as prospective teachers. Although the realization of practical knowledge of real-world conflict has been challenging, it has become a chance to have confidence with the role of parents and the role of teachers in the future.

In this study, we set the occupational satisfaction and communication ability of clinical dental hygienists as the main variables, and investigated the factors that affect communication within the organization to improve the work of dental hygienists. Self-reporting questionnaires were administered to 200 dental hygienists working in dental hospitals and dental clinics in Seoul and Gyeonggi Province from May 18, 2019 to June 12, 2019. We analyzed the data with Pearson correlation analysis and multiple regression analysis. The significance level was set at 0.05. Research results: Job satisfaction (r=0.193, p<0.05) and communication ability (r=0.404, p<.001) showed a significant positive correlation with intra-organizational communication, and individual communication ability (β=0.461, P<.001), which was found to have a significant effect on communication within this organization. Therefore, in order to improve the communication skills of dental hygienists, they should be proud of their work as professionals, enhance their job satisfaction, and be able to have a clear expression of their own intentions and effective dialogue. Efforts should be made to provide opportunities such as opening related lectures during internal education and maintenance education.

Recently, mobile marketing is becoming one of the major topics of interest to the marketing discipline. Emerging from rapid developments in mobile technology, it has created opportunities for new and innovative mobile services. Also, it is enabling to conduct always-on connections that consumers can interact anytime and anywhere. Especially, mobile devices place themselves to the core means of mobile-commerce which to execute a function as a distribution channel in mobile environments. Although the adoption researches about innovative services or technologies had executed in marketing areas over the past decades, most researches just expanded or modified existing theories and explanation models. There has been little study on the comprehensive and systematic review of adoption process. Therefore, it deserves to be considered prior usage experiences of the existing channels(CL) and attractiveness of the new channel(CLalt) based on social exchange theory. In order to address this void, this study unifies components of perceived attributes in the each dimensions (ie. benefit, cost, and risk dimensions) and explores prior usage experiences of the existing channels on adoption intention in electronic financial service channels through developing comprehensive model and employing empirical test for the hierarchy of effects model. Based on these empirical results, this study suggests managerial implications for new channel management in electronic financial service areas by focusing on the prior usage experiences of the existing objects on adoption intention and perceived attributes of ubiquitous-based mobile service channel.

Prediction and control of nitrogen oxides (NO_x) emission is of great interest in industry due to stricter environmental regulations. Herein, we propose an artificial intelligence (AI)-based framework for prediction of NO_x emission. The framework includes pre-processing of data for training of neural networks and evaluation of the AI-based models. In this work, Long-Short-Term Memory (LSTM), one of the recurrent neural networks, was adopted to reflect the time series characteristics of NO_x emissions. A decision tree was used to determine a time window of LSTM prior to training of the network. The neural network was trained with operational data from a heating furnace. The optimal model was obtained by optimizing hyper-parameters. The LSTM model provided a reliable prediction of NO_x emission for both training and test data, showing an accuracy of 93% or more. The application of the proposed AI-based framework will provide new opportunities for predicting the emission of various air pollutants with time series characteristics.

This study attempts to determine the strategy to improve the quality of staff supervision by exploring the experiences of the staff supervision in community welfare centers. For this purpose, multiple case study was performed by conducting in-depth interviews with 10 supervisors for the analysis data and analyzing the resulting themes. The key subjects from their experience were 'Supervisors recognize and prepare the supervision as Challenge and Aspiration', 'Supervision leaves only chaos and frustration', and 'Inspiration from the supervisor and infinite effort result in fruit'. Based on these results, this study suggests the following practical suggestions for the educational, administrative and supportive functions of Supervision. First, educational functions should be proposed as an extension of supervisor's education opportunities and manuals related to educational growth of supervision. Second, the administrative function should be changed to evaluate social welfare institution's evaluation framework so as to evaluate the supervision internal regulation and supervision according to it and various supervision models should be developed. Third, supportive supervision function that can be encouraged for supervisees should be enhanced. This study was meaningful because it presents specific suggestions for supervisors and supervisee's relation and situation in the community welfare center through the qualitative research method.

Recently, the peptide(or protein)-polymer hybrid materials (PPs) were sought in many research areas as potential building blocks for assembling nanostructures in selective solvents. In PPs, the facile routes of preparing well-defined peptide-polymer bio-conjugates and their specific activities in various applications are important issues. Our strategy to prepare the peptide-polymer hybrid materials was to combine atom transfer radical polymerization (ATRP) method with solid phase peptide synthesis. The standard solid phase peptide synthesis method was employed to prepare the PYGK (proline-tyrosine-glycine-lysine) peptide. PYGK is an analogue peptide, PFGK (proline-phenylalanine-glycine-lysine), which interacted with plasminogen in fibrinolysis. The peptide and the peptide-initiator were characterized with MALDI-TOF mass spectrometry and $^1H$ NMR spectrometer. The peptide-polymer, pSt-PYGK was characterized by GPC, IR, $^1H$ NMR spectrometer and TLC. Spherical micellar aggregates were determined by TEM and SEM. Current synthesis methodology suggested opportunities to create the well-defined peptide-polymer hybrid materials with specific binding activity.

Ni-base superalloys are used extensively in industry, both in aeroengines and land based turbines. About 60% by weight of most modern gas turbine engine structural components are made of Ni-base superalloys. To satisfy practical demands, the efficiency of gas turbine engines has been steadily and systematically increased by design modifications to handle higher turbine inlet or firing temperatures. However, the increase in operating temperatures has lead to a decrease in the life of components and increase in costs of replacement. Moreover, around 80% of the large frame size industrial/utility gas turbines operating in the world today were installed in the mid-sixties to early seventies and are now 25 to 30 years old. Consequently, there are greater opportunities now to repair and refurbish the older models. Basically, there are two major factors influencing the weldability of the cast alloys: strain-age cracking and liquation cracking. Susceptibility to strain-age cracking is due to the total Ti plus AI content of the alloy; Liquation cracking is due either to the presence of low melting constituents or constitutional liquation of constituents. Though Rene 41 superalloy has 4.5wt.% total Ti and Al content and falls just below the safe limit proposed by Prager et al., controlled grain size and special heat treatments are needed to obtain crack-free welds. Varying heat treatments and filler materials were used in a laboratory study, then the actual welding of service parts was carried out to verity the possibility of crack-tree weld of components fabricated from Rene 41 superalloy. The microstructural observations indicated that there were two kinds of carbides in the FCC matrix. MC carbides were located along the grain boundaries, while M$_{23}$C$_{6}$ carbide was located both inter and intra granularly. Two kinds of filler materials, Rene 41 and Hastelloy X were used to gas tungsten arc weld a patch into the sheet metal, along with varying pre-weld heat treatments. The microstructure, hardness and tensile tests were determined. The service distressed parts were categorized into three classes: with large cracks, with medium cracks and with small or no visible cracks. No significant difference in microstructure among the specimens was observed. Specimens were cut from the corner and the straight edge of the patch repair, away from the corner. The only cracks present were found to be associated with inadequate surface preparation to remove oxidation. Guidelines for oxide removal and the welding procedures developed in the research enabled crack-free welds to be produced.d.

The product categories that can be sold on-line are expanding. It is interesting to see which product categories have more sales possibilities on internet. Small-sized firms' products have low distribution coverage, low brand recognition, bigger dispersion in the perception on the values which consist of quality vs. price, and higher possibilities of perceived purchase risks. Since on-line shopping is supposed to provide opportunities to small-sized firms that have low distribution and brand power, it is quite necessary to evaluate the fitness of on-line sales for small-sized firms' product categories. There are virtually no research studies on the on-line sales for small-sized firms' product categories. In this study, based on the integration of SEC, FCB, and related concepts, we develop new theoretical framework and test the fitness of on-line sales for small-sized firms' product categories by conducting empirical analysis. The empirical results on 17 product categories show that SEC, FCB, purchase risks, brand factors are somewhat related. Unlike previous studies, since the fitness of SEC and on-line sales are not clearly shown, we need to consider those problems within inter-related multiple frameworks. That is, it is necessary to evaluate the fitness of on-line sales after defining the product categories within the integrated multiple frameworks rather than within the single framework.

This paper aims at drawing policy schemes to establish marine clusters so as to enhance Korea's global port competitiveness and applying them to its national management for the advancement of national economy through policy suggestions. The research method is an integrated approach(IA) that comprises SWOT Method with strategic approaches, HFP Model enhanced by KJ Method and descriptive deductions. Strategic schemes established for the SPLC are followed by the group of geographical proximity, integration of ICT, expansion of the interchange of ICT & opportunities of ET, integration of ICT services with marine technologies, supply of integrated services in the SPLC and implementation of organizational policies. In order to make a specific implementation of strategic establishment schemes of the SPLC, we need to select a promotion entity. It is advised to establish the joint organization of the public sector and the private sector, which is considered most desirable. In practice, it is to be followed by promoting support schemes of the organizational policy on the level of national management. In order to reinforce this study, further compensative and proactive researches on the offshore sector with marine clusters are required in terms of the development of the high value added 'blue' ocean.
