Objective: This study aimed to report the improvement in a patient with allergic contact dermatitis treated with Sihogyeji-tang based on the Shanghanlun disease pattern identification diagnostic system (DPIDS). Methods: According to the Shanghanlun DPIDS, the patient with allergic contact dermatitis was diagnosed with greater yang disease chest bind (Shanghanlun provision 146), and was administered Sihogyeji-tang for 90 days. The results were evaluated using the Dermatological Life Quality Index (DLQI) and a visual analog scale (VAS). Results: After taking Sihogyeji-tang for 90 days, the DLQI decreased from 28 points to 8 points and the VAS decreased from 10 points to 3 points. Conclusions: This case shows the potential of treatment through herbal medicine for allergic contact dermatitis using the Shanghanlun DPIDS.

Consider a p-variate($p{\geq}3$) normal distribution with mean ${\theta}$ and covariance matrix ${\sum}={\sigma}^2{\mathbf{I}}_p$ for any unknown scalar ${\sigma}^2$. In this paper we improve the James-Stein estimator of ${\theta}$ in cases of shrinking toward some vectors using the Stein variance estimator. It is also shown that this domination does not hold for the positive part versions of these estimators.

LiDAR (Light Detection And Ranging) strip adjustment is process to improve geo-referencing of the ALS (Airborne Laser Scanner) strips that leads to seamless LiDAR data. Multiple strips are required to collect data over the large areas, thus the strips are overlapped in order to ensure data continuity. The LSA (LiDAR Strip Adjustment) consists of identifying corresponding features and minimizing discrepancies in the overlapping strips. The corresponding features are utilized as control features to estimate transformation parameters. This paper applied SURF (Speeded Up Robust Feature) to identify corresponding features. To improve determination of the corresponding feature, false matching points were removed by applying three schemes: (1) minimizing distance of the SURF feature vectors, (2) selecting reliable matching feature with high cross-correlation, and (3) reflecting geometric characteristics of the matching pattern. In the strip adjustment procedure, corresponding points having large residuals were removed iteratively that could achieve improvement of accuracy of the LSA eventually. Only a few iterations were required to reach reasonably high accuracy. The experiments with simulated and real data show that the proposed method is practical and effective to airborne LSA. At least 80 % accuracy improvement was achieved in terms of RMSE (Root Mean Square Error) after applying the proposed schemes.

Purpose: This study aimed to investigate the effect of angular joint mobilization (AJM) on the shoulder pain, range of motion, and functional improvement in a patient with shoulder adhesive capsulitis. Methods: The patient diagnosed with right shoulder adhesive capsulitis by an orthopedic surgeon was a 60-year-old male, right hand/arm dominant, with a height of 175 cm and weight of 75 kg. The patient received 12 sessions of AJM once or twice per week for eight weeks. AJM was applied for 5 min each of flexion, abduction, external rotation, internal rotation, for a total of 20 min per session. The visual analog scale, the goniometer, and the Oxford shoulder score were used to measure pain, range of motion, and shoulder pain & disability index, respectively. Results: After all the treatments, the pain decreased from 6 to 2 points. The range of motion increased in flexion by $54.3^{\circ}$ from $125^{\circ}$ to $179.3^{\circ}$, abduction by $38^{\circ}$ from $140^{\circ}$ to $178^{\circ}$, external rotation by $54.4^{\circ}$ from $30.3^{\circ}$ to $84.7^{\circ}$, and internal rotation by $25^{\circ}$ from $45^{\circ}$ to $70^{\circ}$. The shoulder disability index decreased from 33 points to 17 points. Conclusion: This study found that AJM has a positive effect on the improvement of shoulder pain, range of motion, and function in a patient with shoulder adhesive capsulitis. Further studies on AJM are needed in the future.

This study investigated 110 contractual industries to identify the effects of curriculum development and educational environment improvement through Ulsan College LINC+ Program on job education and training. As a result of the study, core competency and job competency were 5.73 points each in field practice and educational environment, and job performance was significant with OJT 5.58 points and 5.74 points for educational environment(p<0.05). The relationship between suitability of the curriculum, educational environment, and recruitment performance was significant with 5.73 points for OJT, 5.74 points for field training during the education and training period, and 5.79 points for educational environment, and job reeducation/training expense was significant with 5.73 points for OJT and 5.79 points for educational environment(p<0.05). Also, students who completed the LINC+business curriculum shortened their job period by 1 to 6 months in 86.3% of the respondents, and responded that the education expense for new employees was reduced. Therefore, it was identified that the LINC+ Program of Ulsan College has the effect of shortening the job adaptation period and reducing education expenses for new employees by operating the curriculum reflecting the needs of the industry and improving the same educational environment as the industrial field.

Purpose: The purpose of this study was to investigate the effect of the number of measurement points on the calculation of transverse relaxation time (T2) with a focus on muscle T2. Materials and Methods: This study assumed that muscle T2 was comprised of a single component. Two phantom types were measured, 1 each for long ("phantom") and short T2 ("polyvinyl alcohol gel"). Right calf muscle T2 measurements were conducted in 9 healthy male volunteers using multiple-spin-echo magnetic resonance imaging. For phantoms and muscle (medial gastrocnemius), 5 regions of interests were selected. All region of interest values were expressed as the mean ${\pm}$ standard deviation. The T2 effective signal-ratio characteristics were used as an index to evaluate the magnetic resonance image quality for the calculation of T2 from T2-weighted images. The T2 accuracy was evaluated to determine the T2 reproducibility and the goodness-of-fit from the probability Q. Results: For the phantom and polyvinyl alcohol gel, the standard deviation of the magnetic resonance image signal at each echo time was narrow and mono-exponential, which caused large variations in the muscle T2 decay curves. The T2 effective signal-ratio change varied with T2, with the greatest decreases apparent for a short T2. There were no significant differences in T2 reproducibility when > 3 measurement points were used. There were no significant differences in goodness-of-fit when > 6 measurement points were used. Although the measurement point evaluations were stable when > 3 measurement points were used, calculation of T2 using 4 measurement points had the highest accuracy according to the goodness-of-fit. Even if the number of measurement points was increased, there was little improvement in the probability Q. Conclusion: Four measurement points gave excellent reproducibility and goodness-of-fit when muscle T2 was considered mono-exponential.
