In this paper, we propose the augmented reality(AR) based driving navigation based on robust lane detection method to dynamic environment changes. The proposed technique uses the detected lane position as a marker which is a key element for enhancing driving information. We propose Symmetrical Local Threshold(SLT) algorithm which is able to robustly detect lane to dynamic illumination environment change such as shadows. In addition, by using Morphology operation and Connected Component Analysis(CCA) algorithm, it is possible to minimize noises in the image, and Region Of Interest(ROI) is defined through region division using a straight line passing through several vanishing points We also propose the augmented reality aided visualization method for Interchange(IC) and driving navigation using reference point detection based on the detected lane coordinates inside and outside the ROI. Validation experiments were carried out to assess the accuracy and robustness of the proposed system in vairous environment changes. The average accuracy of the proposed system in daytime, nighttime, rainy day, and cloudy day is 79.3% on 4600 images. The results of the proposed system for AR based IC and driving navigation were also presented. We are hopeful that the proposed research will open a new discussion on AR based driving navigation platforms, and thus, that such efforts will enrich the autonomous vehicle services in the near future.

Prostate cancer ranks as the world's second most frequently diagnosed cancer among men, and is responsible for the fifth highest number of cancer-related deaths in this population. The development of effective diagnostic and therapeutic approaches for prostate cancer remains a major challenge in the field of oncology. Over the past few years, the prostate-specific membrane antigen (PSMA) has raised as a hopeful tracer for the diagnosis and treatment of prostate cancer.Various radioisotopes, such as ¹³¹I, ^99mTc, ⁶⁸Ga, and ¹⁷⁷Lu, have been used to label PSMA analogues, with varying degrees of success. Among these, ⁶⁸Ga-PSMA-11 and ¹⁷⁷Lu-PSMA-617 have emerged as the most promising radioligands for clinical use. Recently, researchers have been exploring the use of other radioisotopes, such as ²¹¹At, ⁸⁹Zr, ^64/67Cu, and ^203/212Pb, for the labeling of PSMA-targeted radioligands. These radioisotopes have unique properties that may offer advantages over existing radioligands, such as longer half-lives, higher specific activities, and different emission profiles. Efforts are currently underway to develop these radiopharmaceuticals and make them more widely available for clinical use. These exciting developments highlight the potential of PSMA-targeted radioligands for the diagnosis and treatment of prostate cancer, and provided significant implications for the management of this disease in the future. The current study aims to provide a comprehensive summary of the latest research and clinical applications of radiolabeled PSMA inhibitors for diagnoses and therapy of prostate cancer, emphasizing the exciting developments in the field and their potential impact on clinical practice.

Objective : Treatments for patients with mental retardation and pervasive developmental disorders are not curative, and are designed to help those with disabilities adjust to their environments and daily demands. As clinicians, the present authors tried to find agents with potentially curative properties. Among the numerous herbal formulations available, we chose and assessed Gami-jiwhang-tang (GJT) in the hope that it would improve cognitive development of children. Methods : Subjects were typically-developing healthy, 7- to 8-year-old boys and girls living in Seoul, Korea. The experimental group took GJT for six weeks and was followed up six weeks after discontinuation of GJT. The control group was assessed at the same intervals but did not receive placebos. To measure the effects of GJT, neuropsychological tests and intelligence test were taken before commencing GJT and twelve weeks later. Resulets and Conclusion : For all of the ANOVAs, the treatment by time interaction terms was not significant. However, the experimental group showed the tendency to be progressed in most subscales compared with the control group, especially on performance intelligence, visual organization, and verbal fluency. Conclusion : Although GJT failed to reveal significant improvement in cognition, we remain hopeful about the compound and believe that it should be evaluated by a double-blind, placebo-controlled trial in the future.

This study examined and identified the relationship between the level of hope and self-care agency in hemodialysis patients. The purpose of the study was to reveal that hope is an essential factor to enhance self-care agency and to prepare the basic materials to help nurse the patients. The subjects for this study consisted of 108 persons who undergoing hemodialysis from 2 hospital, 2 hemodialysis center in Pusan, Korea. The degree of hope was measured by the questionnaire that has been developed by Miller. The self-care agency was measured by the questionnaire that has been developed by Kearney B.Y & Fleisher B.J. The collected data were analyzed by descriptive statistics and t-test. one-way ANOVA and Pearson's Correlation Coefficient with SPSS WIN program. Results were obtained as follows: 1) The mean scores of hope were $131.77{\pm}25.77$(range 67-195). The rate of hope classified said that the lowest hope was 2.8% and low hope was 27.8%. 2) The mean scores of self-care agency were $143.78{\pm}23.63$(range 74-187). The degree of self-care agency classified said that the rate of self-care agency deficiency was 0.9% and low self-care agency was 12.0%. 3) The hope was significantly related to self-care agency. That is, the higher the hope score was， the higher the level of self-care agency score(r=0.668，p=0.001) was. In this result, there were hemodialysis patients who have very low hope score and self-care agency score. In this cases self-care agency can be increased by encouraging the patients to be more hopeful. Conclusively nurses should access the degree of hope and self-care agency of hemodialysis patients individually and apply the hope therapy in order that the patient have higher hope than before.

The Korean government had introduced the industrial safety & hygiene consultant(ISHC) system to improve worksite health and safety level by providing specialized industrial safety & hygiene(S&H) services in 1996. Despite of initial hopeful expectation it has been said that this plan might fail to settled down and maintain its purpose. This study was designed to investigate operational issues and problems concerning the ISHC system, that would direct the way of change and future role. Questionnaire were sent to ISHC, professional engineer, agencies for occupational injury prevention, S&H specialist in the corporation nationwide and totally 256 people responded to in having 62.7% of response rate. The result of this study were as follows; 1. One hundred and forty two cases of safety assessment and 27 cases of process safety reports were the six years' results since 1996 the ISHC program had first been introduced. This results showed that injury prevention activities of ISHC had been stagnant. 2. The 78.8% of respondents had negative opinion about injury prevention activities of ISHC program. 3. The operational problems of ISHC were lack of understanding of company about ISHC, low systematization of work items, duty overlapping with agencies for occupational injury prevention, low support by government. in order. 4. It was suggested that abolition of ISHC and promotion of professional engineer system should be considered. 5. To promote professional engineer system it was suggested that the professional engineer could conduct consulting service and ISHC should be integrated with the expert system.

The influenza A (H1N1) virus, also known as swine flu is a leading cause of morbidity and mortality since 2009. There is a need to explore novel anti-viral drugs for overcoming the epidemics. Traditionally, different plant extracts of garlic, ginger, kalmegh, ajwain, green tea, turmeric, menthe, tulsi, etc. have been used as hopeful source of prevention and treatment of human influenza. The H1N1 virus contains an important glycoprotein, known as neuraminidase (NA) that is mainly responsible for initiation of viral infection and is essential for the life cycle of H1N1. It is responsible for sialic acid cleavage from glycans of the infected cell. We employed amino acid sequence of H1N1 NA to predict the tertiary structure using Phyre2 server and validated using ProCheck, ProSA, ProQ, and ERRAT server. Further, the modelled structure was docked with thirteen natural compounds of plant origin using AutoDock4.2. Most of the natural compounds showed effective inhibitory activity against H1N1 NA in binding condition. This study also highlights interaction of these natural inhibitors with amino residues of NA protein. Furthermore, among 13 natural compounds, theaflavin, found in green tea, was observed to inhibit H1N1 NA proteins strongly supported by lowest docking energy. Hence, it may be of interest to consider theaflavin for further in vitro and in vivo evaluation.
