Smart HACCP is a system that can check the monitoring of critical control point (CCP) in real time to implement improvement measures immediately after departure from limit criteria and prevent falsification of data by digitizing handwritten records. In this study, we developed the analysis model for the effectiveness ofsmart HACCP to compare and analyze with existing HACCP. By introducing of smart HACCP system, the evaluation index value of HACCP effectiveness for HACCP-certificated companies on a small scale increased by 9.25 points, corresponding to 11.52% of increase rate. General HACCP-certificated companies showed 4.52 point and 5.00% of increase rate by introducing of smart HACCP system. Thus, it was confirmed that the introduction of smart HACCP system contributes to the improvement of food safety management and especially it would be more effective for HACCP-certificated companies on a small scale than general HACCP-certificated companies.

Purpose: In this study, we compared low-power $CO_2$ laser treatment to ultrasonic scaling, which is generally approved as a power-driven mechanical instrumentation, and evaluated both of these treatments regarding their clinical effectiveness and change in the volume of in GCF. Material and methods: 20 patients who had gingivitis were selected. all of patients has no systemic problems. Randomly selected, one quadrant received ultrasonic scaling only, another quadrant received ultrasonic scaling and $CO_2$ laser irradiation, the other quadrant received $CO_2$ laser irradiation only. Clinical parameters measured at baseline, 1 weeks, 2weeks, 4weeks and 8weeks. Result: Pocket probing depth and clinical attachment level were not changed during study period. Gingival index of all group were improved after treatment. At 1 weeks after treatment, Gingival index of ultrasonic scaling group was only significantly different compared to control group. At 2 weeks after treatment, gingival index of all experimental group were significantly different compared to control group. At 4 and 8 weeks after treatment, gingival index of all group were increased, but experimental group were lower than control group. Sulcus bleeding index was similar to the results of gingival index. At 1 weeks after treatment, all experimental group were significantly different compared to control group and it maintained during study. At 2 weeks after treatment, sulcus bleeding index of all group were lowest during study. Gingival crevicular fluid were measured with $Periotron^{(R)}$ 8000($Oraflow^{(R)}$, Inc. USA). At baseline, all group were showed moderately severe condition. At 1 week after treatment, laser treatment only group was reduced quantity of gingival crevicular fluid mostly, and all group were reduced quantity of gingival crevicular fluid. At 2 weeks after treatment, all group were health state. At 4 and 8 weeks after treatment, all group were showed recurrent of inflammation, and control group was the most significantly increased. Conclusion: This study showed that the effects of $CO_2$ laser treatment were similar to conventional ultrasonic scaling and this result remained longer than plaque control only. These results suggest possibility of $CO_2$ laser treatment for altered periodontal therapy.

Objectives The purpose of this study is to compare the effects between the KL-Grade and improvement of knee pain treated by Korean Medicine therapy. Methods 114 patients who received inpatient treatment from July 2014 to May 2017 in the Daejeon Jaseng of Korean Medicine Hospital were divided into 5 groups by the KL-Grade. All patients received a combination of treatment including acupunture, pharmacopunture, herbal medication. They were compared and analyzed on the basis of improvement between measuring Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) as they were hospitalized and as they were discharged. The statistically significance was evaluated by SPSS 23.0 for windows. Results After treatment, KL-Grade 0 group's Numeric Rating Scale (NRS), Western Ontario and McMaster Universities Arthritis Index (WOMAC Index), EuroQol-5 Dimension Index (EQ-5D Index) improvement was $2.02{\pm}1.69$, $7.50{\pm}9.67$ and $0.11{\pm}0.15$ respectively. KL-Grade 1 group's improvement was $2.09{\pm}1.23$, $11.75{\pm}13.99$ and $0.12{\pm}0.13$ respectively. KL-Grade 2 group's improvement was $1.60{\pm}1.07$ and $14.70{\pm}14.19$ respectively. But In this group, EQ-5D Index has decreased by $0.01{\pm}0.10$. KL-Grade 3 group's improvement was $1.88{\pm}1.31$, $7.81{\pm}13.35$ and $0.13{\pm}0.20$ respectively (p<0.034). In the case of KL-Grade 4, the population was not statistically significant (N=2) and therefore excluded from statistical significance. And there was no statistically significance between 4 group's improvement after treatment (p>0.05). Conclusions The above study showed that Korean medicine treatments showed significant therapeutic effects on knee pain and degenerative knee joints, but there was no significant difference in the effectiveness of degenerative arthritis (KL-Grade).

Purpose: To evaluate the effectiveness of temporomandibular joint (TMJ) disorder follow-up and determine the factors that affect the TMJ bone scan hot spot numerical value (bone scan value), and to compare this value to the diagnosis of patients with temporomandibular joint disorders (TMD), their treatment options, and the resolution of their symptoms. Materials and Methods: A retrospective cohort study was performed on 24 patients (four males, 20 females) who received TMD treatment in the Section of Dentistry, Seoul National University Bundang Hospital (Seongnam, Korea) from 2007 to 2014. An analysis of the significance test and correlation between TMD diagnosis, treatment options, a baseline the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) questionnaire, treatment before and after the clinical examination and subjective progress, and TMJ bone scan value change were completed by using SPSS version 12.0. Result: Although only 14 patients had bony factors that caused TMD, the average pre-treatment bone scan value of the all patients was $4.29{\pm}0.31$, which is higher than the finding for osteoarthritis (3.88), and reduced post-treatment bone scan value was found to be without a statistically significant difference (P=0.056). After the treatments, clinical symptoms in 18 patients disappeared, and six patients did not require additional treatment, although they still displayed subjective symptoms. It was observed that the higher the pre-treatment bone scan value, nonspecific physical symptoms, chronic pain index, characteristic pain intensity, disability score, were, the lower the post-treatment bone scan value was. And this reduced post-treatment bone scan value tendency was not shown with the pre-treatment depression index, but there was not a statistical difference. Conclusion: The post-treatment TMJ bone scan value tended to be insignificantly reduced in the 24 patients whose clinical symptoms were improved (P=0.056). Moreover, the TMJ bone scan value showed no relation to the TMD type or its related symptoms.

Background: We first launched the case management program for diabetic patients who were registered in NHIC (National Health Insurance Corporation) in Korea and conducted this study to assess the effectiveness of the program. Methods: During the period from October in 2002 to March in 2003, 30 case managers performed the program for 71 diabetic patients. We evaluated the effectiveness of the program based on the results of fasting blood sugar level, two hour post-prandial blood sugar level, knowledge for diabetes, difficulty index in diabetes management, and the health risk factor changes of them. We analyzed results related to these factors through $x^2$ test and paired t-test. Results: The ave rage age of the subjects was 58.9. and the numbers of women and men were 43 and 28 respectively. The fasting blood sugar level and two hour post-prandial blood sugar level decreased from 164.3mg/dl to 146.5mg/dl and from 224.0mg/dl to 203.0mg/dl respectively. The knowledge for diabetes and difficulty index in diabetes management changed from 8.13 to 9.10 and from 3.52 to 2.91 respectively, and these changes were the positive. We observed improvement in self-test of sugar level, foot management, oral hygiene and proper medication but not in self-test of nutritional management. Conclusions: This study revealed that the case management program for diabetic patients who were registered in NHIC is significantly effective. However, the program need to study further to understand its long-term effects.
