Background : The prevalence of the chronic metabolic disease is increasing due to the aging society. Therefore, Korean Society of Health-system Pharmacists (KSHP) has a specialty pharmacist system to improve the professionalism of pharmacists. The purpose of this study is to suggest the difference between specialty pharmacist and non-specialty pharmacist with regards to their knowledge, delivery of information on medication, service provision, and job satisfaction. Methods : An online survey research was conducted for hospital pharmacists. The reliability of the questionnaire items was presented using Cronbach's ${\alpha}$ test. The t-test or ANOVA analysis was used for evaluating differences in continuous variables. Results : A total of 171 pharmacists responded to the questionnaire, and 87.7% of the respondents were aged less than 30 years (76.6%) and four-year graduates (86.0%). Typically, 108 (63.2%) were candidates for the pharmacist's specialty certificate, and the remaining 63 (36.8%) were not enrolled. Considering the field of specialty with overlapping, the total number of certificated patients was 140 (26.3% of the total of 532 in 2016). The results of the reliability analysis of the specific questionnaire showed that the Cronbach's ${\alpha}$ value was over 0.78. There was no significant difference in customer directionality between the two groups. However, there was a significant difference (p<0.05) with respect to overall knowledge about the treatment process, drug efficacy, and side effects, information about medicines and adverse drug reactions, and in providing appropriate information to medical staff including patients and physicians. Conclusions : The pharmacist with specialization showed a positive result of self-evaluation of items such as knowledge about drugs, communication of information on medications, and service provision, compared to other pharmacists, and the result was in correlation with the numbers of specialization. There was no difference in job satisfaction related to working environment. Henceforth, it is hypothesized that there is a necessity for continuous improvement in the working environment to suit the purpose of the pharmacy specialist system.

In this paper, we suggest a secure data dissemination by Lightweight Individual Encryption Multicast scheme over wireless sensor networks using the individual encryption method with Forward Error Correction instead of the group key encryption method. In wireless sensor networks, a sink node disseminates multicast data to the number of sensor nodes to update the up to date software such as network re-programming and here the group key encryption method is the general approach to provide a secure transmission. This group key encryption approach involves re-key management to provide a strong secure content distribution, however it is complicated to provide group key management services in wireless sensor networks due to limited resources of computing, storage, and communication. Although it is possible to control an individual node, the cost problem about individual encryption comes up and the individual encryption method is difficult to apply in multicast data transmission on wireless sensor networks. Therefore we only use 0.16% of individually encrypted packets to securely transmit data with the unicast to every node and the rest 99.84% non-encrypted encoded packets is transmitted with the multicast for network performance.

This study analyzed the non-cognitive domains (self-management competency, interpersonal relations competency) and cognitive domains (physical communication competency, comprehensive reasoning ability) among K-CESA for college students in the Division of Architecture at 𐩒𐩒 University and construction company workers, after which a training program for college students was designed. A K-CESA diagnostic evaluation was conducted on 25 construction company workers and 36 students in the senior and junior years of the division of Architecture. To identify the discrepancies among the two groups, "One-way ANOVA", a mean difference test, was performed and the Scheffe verification system was conducted as an after-measure. The empirical analysis of this study was verified at the significance level p <.05, and statistical processing was analyzed utilizing the SPSS WIN. 23.0 program. The major findings are as follows: first, the significant point of difference between the college students and construction company workers were located in five skills (goal-oriented planning and execution skills, cooperative skills, intervention skills, leadership skills, speaking skills, analytical reasoning skills); second, the education program was developed to improve the goal-oriented planning, execution ability and analytical reasoning ability through the expert-required analysis and study research. Through follow-up studies, I suggested that there is a need to develop courses that compare the competencies of various majors and workers in public institutions, corporations and other organizations.

Gait analysis is one of the research fields for obtaining various information related to gait by analyzing human ambulation. It has been studied for a long time not only in the medical field but also in various academic areas such as mechanical engineering, electronic engineering, and computer engineering. Efforts have been made to determine whether there is a problem with gait through gait analysis. In this paper, as a pre-step to find out gait abnormalities, it is investigated whether it is possible to differentiate whether experiment participants wear elderly simulation suit or not by applying gait data to machine learning models for the same person. For a total of 45 participants, each gait data was collected before and after wearing the simulation suit, and a total of six machine learning models were used to learn the collected data. As a result of using an artificial neural network model to distinguish whether or not the participants wear the suit, it showed 99% accuracy. What this study suggests is that we explored the possibility of judging the presence or absence of abnormality in gait by using machine learning.

COVID-19 has been affecting the library, not to mention society as a whole. Especially, there are many changes in the role and service of the university libraries as all the classes of the universities are turned into non-face-to-face and the use of the university libraries is restricted. The changes in users' use of information and communication behavior due to COVID-19 could be an opportunity for new utilization of human and material resources the university libraries have and for the development of services. However, on the contrary, the university libraries could face another crisis if they fail to respond appropriately to current changes. Therefore, it is necessary to grasp, analyze the impact of COVID-19 and plan how to respond. A survey on the effects of COVID-19 and the response of the university libraries and the perceptions of the university libraries found that most university libraries are responding appropriately to COVID-19. However, a survey on the perceptions of the present and future of the university libraries under COVID-19 showed that many survey respondents think COVID-19 would have a negative impact on the university libraries. This means that the changes caused by COVID-19 are causing a crisis and anxiety in the university libraries. Therefore, by working hard together, the university libraries need to present the university libraries' new role, service and direction in the post-COVID-19 era as well as responding to the current situation.

The aim of this study is to demonstrate interaction as a describable field and tries to understand interaction from the perspective of attributes, thus building a theoretical to help interactive designer understand this field by common rule, rather than waste huge time and labor cost on iteration. Since the concept of interaction language has been brought out in 2000, there are varies of related academical studies, but all with defect such as proposed theoretical models are built on a non-uniform scale, or the analyzing perspective are mainly based on researcher's personal experience and being too unobjective. The value of this study is the clustered resource of research which mainly based on academical review. It collected 21 papers researched on interaction paradigm or interaction attributes published since 2000, extracting 19 interaction attribute models which contains 174 interaction attributes. Furthermore, these 174 attributes were re-clustered based on a more unified standard scale, and the two theoretical models summarized from it are respectively focuses on interaction control and interaction experience, both of which covered 6 independent attributes. The propose of this theoretical models and the analyzation of the cluster static will contribute on further revealing of the importance of interaction attribute, or the attention interaction attribute has been paid on. Also, in this regard, the interactive designer could reasonably allocate their energy during design process, and the future potential on various direction of interaction design could be discussed.

Additional frequencies are allocated in maritime digital data exchange to alleviate overload of the VHF data link. The shipborne ad-hoc network (SANET) for this frequencies was subsequently proposed, which provides various IP-based services to ships on behalf of satellite communications. In SANET, a ship should determine its own IP address to achieve IP connectivity to the shore. Accordingly, this paper proposes a SANET configuration (SANETconf) protocol as an IP configuration protocol. SANETconf propagates non-overlapping IP addresses across the network from the shore to ships. A ship obtains its IP address by exchanging Request and Response messages with its neighbors. Therefore, SANETconf eliminates the process of DAD and managing the movement of ships. Extensive simulations were performed to verify the applicability of SANETconf. Based on results, 85% of the ships can determine their own IP address within one frame. Also, SANETconf has a high resource efficiency by using 0.024 percent of resources for IP configuration.

In the medical field, disease diagnosis and prediction research using artificial intelligence technology is being actively conducted. It is being released as a variety of products for disease diagnosis and prediction, which are most widely used in the application of artificial intelligence technology based on medical images. Artificial intelligence is being applied to diagnose diseases, to classify diseases into benign and malignant, and to separate disease regions for use in identification or reading according to the risk of disease. Recently, in connection with cloud technology, its utility as a service product is increasing. Among the diseases dealt with in this paper, liver disease is a disease with very high risk because it is difficult to diagnose early due to the lack of pain. Artificial intelligence technology was introduced based on medical images as a non-invasive diagnostic method for diagnosing these diseases. We describe the development of a web service to help the most meaningful clinical reading of liver cirrhosis patients. Then, it shows the web service process and shows the operation screen of each process and the final result screen. It is expected that the proposed service will be able to diagnose liver cirrhosis at an early stage and help patients recover through rapid treatment.
