The purpose of this study is to present the EV range in HDRI acquisition process to create luminance map. The proposed method in this study is to capture the scene at EV ${\pm}0$ that is the longest exposure points and reference point in the scene. With this reference point, sets of 25 LDRI test case were taken manually at ${\pm}2$ EV using the aperture-priority manual mode. The 25 HDRIs were created using Adobe Photoshop. The HDRIs were then imported Radiance lighting simulation program to be analyzed into falsecolor. The analysis results of the 25 HDRIs test case are 50[%] of the all tested case have a margin of error of 10[%]. In case of f/5.6, the luminance map generated with HDRI were similar to the spot luminance meter. As a result, the EV range to reduce error of luminance map generated with HDRI is EV $+2{\sim}{\pm}0{\sim}-10$.

This study is the fundamental report to propose the capability of discarded Bentonite by heat-treatment as concrete mineral admixture. The experiment is performed by flow test of mortar and by compressive strength of 7, 14, 28, 91 days, As a result of experiment about mortar using discarded Bentonite by heat-treatment, in the case of $500^{\circ}C$, $600^{\circ}C$, $700^{\circ}C$, $800^{\circ}C$.60min, compressive strength is superior to the every situation than plain Mortar. Especially, in the case of $700^{\circ}C$.60min, as strength activity index is measured by 109%, it can be applied as concrete mineral admixture. But, flow of Mortar using discarded Bentonite by heat-treatment is decreased about 2.5cm in the case of 30min and about 1.7cm in the case of 60min.

Objectives : This study is desinged in order to evaluate the Poison extraction method for the Atopic dermatitis. Methods : The authors observed the two cases of Atopic dermatitis patients who previously used steroid-based ointment. for treating the Poison Extraction Method. Conclusions : 1. In case 1, the patient with mild case of Atopic dermatitis in face is treated with the Poison extraction method. Rash symptoms intensed for first few days. As sweating appeared in the local area from the seventh day, all the symptoms was disappeared rapidly. No recurrence was found. 2. In case 2, the patient with severe case of Atopic dermatitis in whole body is treated with the Poison extraction method. The symptoms intensed after two months and all the symptoms of itchiness, rash, scaly letter dissapeared in the third and fourth months. No recurrence was found. 3. In both cases of mild and severe cases of Atopic dermatitis. all the symptoms were disappeared and no recurrence was found with the Poison Extraction Method.

In this study, we propose the guideline with strategic model for new product development. To establish the guideline, 1) we classify several types of successful surveyed cases that achieved open innovation through applying crowdsourcing into new product development environment, 2) draw case maps using two or three axis with characteristics such as: step of product development process, crowdsourcing frequency, and product type of each case, 3) define the type of applying crowdsourcing into new product development environment based on case analysis results, and tabulate a crowdsourcing type based on the defined crowdsourcing type, 4) finally, suggest the guideline with multiple points of view which embrace type of crowd, community management, participation method, knowledge adoption method, and reward policy. Using the suggested guideline will help a company to design and establish open innovation in new business model related to product development area.

In case of Lighting occurs in Domestic combined distribution line, normally the voltage for the neutral line increase dramatically. General connection for underground cable is bundled common earth type so the lightning over voltage increase at the concentric-neutral line is not big enough to give impact on cable sheath. But in case of Non bundled common earth type it is necessary to analyze the phenomena on cable sheath caused by lightening overvoltage. Especially pole and cable joint are the core factor to consider. In this paper concrete pole and cable joint were evaluated in case of Non bundled common earth type combined distribution Line. EMTP simulation model has been designed and several case study were made. Also several experimental test were made to verify the simulation result.

Back ground & Objectives : Bilateral sudden sensorineural hearing loss(SSNHL) is very rare disease. This is the first case report in the oriental medical literature. This study describes a case of bilateral SSNHL with incomplete recovery. Methods : We treated 1 patient who had SSNHL sequentially in both ears. He received oriental and western medical treatments for more than 2 weeks and measured the hearing recovery. For diagnosis on this case, pure tone audiometry was used. The degree of improvement was evaluated by Siegel's Criteria. Results & Conclusions : This patient discharged without hearing improvement. For bilateral SSNHL patients, the result of treatment is important for their qualities of life. But the recovery rate of hearing in bilateral SSNHL is lower than unilateral SSNHL. The oriental medical therapy had some theraputic effects on SSNHL and the theraputic effects on bilateral SSNHL requires further study.

The Objective of this study is to report the results of greater trochanteric pain syndrome (GTPS) patient with Korean medicine therapy. There were insufficient clinical trials and case reports of GTPS treated with Korean medicine, we report the GTPS case remarkably improved treatment results. We treated the patient with acupuncture, acupotomy, pharmacopuncture, Chuna manual therapy and herbal medication. To evaluate the treatment effects, we used the measures including Verbal numerical rating scale, Oswestry disability index and Victorian Institute of Sport Assessment-gluteal tendinopathy scale. After total of 26 days of treatment, the patient's hip pain and disability were greatly reduced, and the outcome measures showed this great improvement. Korean medicine therapy might be effective in GTPS, although further study is needed to determine the role for Korean medicine.

Results Sasang Constitutional Medicine seems to be effective for the symtoms of the patient with diabetic neuropathy in this case. Conclusions This case study shows that Sasang Constitutional Medicine may be an effective treatment for Soyangin's diabetic neuropathy.

Purpose: This study aimed to develop a case-based nursing education program using generative artificial intelligence and to assess its usability and applicability in nursing curriculums. Methods: The program was developed by following the five steps of the ADDIE model: analysis, design, development, implementation, and evaluation. A panel of five nursing professors served as experts to implement and evaluate the program. Results: Utilizing ChatGPT, six program modules were designed and developed based on experiential learning theory. The experts' evaluations confirmed that the program was suitable for case-based learning, highly usable, and applicable to nursing education. Conclusion: Generative artificial intelligence was identified as a valuable tool for enhancing the effectiveness of case-based learning. This study provides insights and future directions for integrating generative artificial intelligence into nursing education. Further research should be attempted to implement and evaluate this program with nursing students.

This study was proceeded to analyze thixotropy of cement paste according to the addition timing of PVA and borax as a basic study of thixotropy of concrete. According to experiment results, the case added borax first and PVA later is that cement paste shows low thixotorpy, and the case added PVA first and borax later is that cement paste shows thixotropy but in certain mix condition fluidity of decrease due to a chemical bond between PVA and borax. The case add PVA and borax simultaneously is that cement paste was expressed thixotropy in all mix condition. Therefore the case add PVA and borax simultaneously is suitable for expressing thixotropy of cement paste.
