Objectives: The purpose of this study was to develop a Na-reduction education program and apply it for cooks who prepare meals in day-care centers. To development of the program was based on increasing the self-awareness of salinity, eating behaviors and enforcing skills of low-Na cooking. Methods: The study was carried out from April to October in 2013, fifty five cooks participated in this program. The Na reduction program composed of 4 sessions of education which included a 90-minute lecture and self-reevaluation of personal salt-sensitivity degree and three low Na recipe cooking classes. In order to measure the effectiveness of the program, the pretest and posttest of salinity of the soups provided by day care centers was conducted at registration and 5 month after the program with the same menu. Results: After the conduct of the program, salimeter using rate was increased from 8.2% to 94.6% after the program and the other measuring instruments using rate was gradually increased. We observed that the score on eating behaviors increased 1.51 points from 38.80 to 40.31 after the intervention program (p < 0.001). Further, increased knowledge and skill provided by the intervention program resulted in improved Na-reduction cooking capability. According to the results from analyzing the soup salinity, the salinity in watery soup was significant reduced from 0.556 to 0.449 0.107 and soybean-paste soup was significant reduced from 0.669 to 0.551 after the intervention program (p < 0.001). Conclusions: As the result of fact, the intervention programs that was based on self-reevaluation, to enforce practical skill and consciousness was effective to serve low sodium menu at day care centers.

Obesity is defined as excessive storage of energy in the form of fat resulting in adverse effect on healthy and longevity. Some data have shown increased incidence of hypertension, diabetes, hypercholesterolemia in overweight individuals and other disorders such as joint disease, cancer have been also associated with obesity. Recently, various commercial diet programs have been introduced for weight reduction without scientific evaluation for clinical effect and safety. The diet program must be based on a sound and scientific rationale and also be safe and nutritionally adequate. Pulmuone $diet^{(R)}$ is a calorie-restricted commercial diet-food, which contains adequate nutritients. The efficacy and safety of Pulmuone diet were evaluated in 28 normal healthy obese females in a prospective study. Each volunteer was placed in 3-week diet program. To observe weight reduction effect, body weight, TSF and AMC were measured every week. To account for safety of this program, blood chemistry test, blood pressure and side effects were monitored every week. Mean body weight was reduced by 3.24kg following diet program, which is statistically significant(P < 0.05) and this weight reduction was related to reduction in fat weight and not muscle weight as shown by the results of TSF and AMC Blood chemistry was not influenced by this program, but blood pressure was significantly reduced following this program. Thought diet program was generally well tolerated in most volunteers, the most frequent side effects are constipation, dizzness and headache. In conclusion, Pulmuone $diet^{(R)}$ program seems to be safe and effective for weight reduction in normal healthy obese females.

This study aimed to develop and evaluate a sugars intake reduction program (SIRP) that was designed to increase the knowledge, attitude, and skills of Korean children aged 5 years regarding sugars intake reduction. A total of 101 children aged 5~6 years from 6 preschools participated in SIRP. SIRP consisted of 4 sessions including 10 activities (e.g., story-telling, arts, experiment, checking nutrition facts, pledge), delivered to children at preschools by nutritionists over a one-month period. Three letters were sent to parents throughout the program to inform them of the children's activities at the preschools and to provide additional information on reducing children's sugars intake. A total of 90 children completed the program; 83 parents of these children completed the SIRP evaluation survey. The children's sugars intake reduction score was significantly increased after attending SIRP. Teachers (n=6) who participated in this program agreed to improve their students' attitudes on reducing sugars intake and to decrease students' behaviors related to sugars intake. Parents agreed to improve their children's attitude on reducing sugars intake and to decrease children's behaviors related to sugars intake. The outcome showed SIRP improved participants' attitudes towards sugars reduction and increased the skills to reduce the sugars intake of children aged 5~6 years. Future studies should examine whether SIRP reduces actual sugars intake among children.

Objectives: This systematic review evaluated the efficacy of the supplementary use of the XP-endo Finisher on bacteria content reduction in the root canal system. Materials and Methods: In-vitro studies evaluating the use of the XP-endo Finisher on bacteria content were searched in four databases in July 2020. Two authors independently screened the studies for eligibility. Data were extracted, and risk of bias was assessed. Data were meta-analyzed by using random-effects model to compare the effect of the supplementary use (experimental) or not (control) of the XP-endo Finisher on bacteria counting reduction, and results from different endodontic protocols were combined. Four studies met the inclusion criteria while 1 study was excluded from the meta-analysis due to its high risk of bias and outlier data. The 3 studies that made it to the meta-analysis had an unclear risk of bias for at least one criterion. Results: No heterogeneity was observed among the results of the studies included in the meta-analysis. The study excluded from the meta-analysis assessing the bacteria counting deep in the dentin demonstrated further bacteria reduction upon the use of the XP-endo Finisher. Conclusions: This systematic review found no evidence supporting the supplementary use of the XP-endo Finisher on further bacteria counting the reduction in the root canal.

The Energy and Green House Gas target management system was launched by the Korean Government in 2010. The Korea Emission Trading System will start in 2015. Therefore, simultaneous pursuit of energy saving and greenhouse emission reduction through energy use rationalization is an important obligation of Korean engineers, who import about 97% of domestic energy consumption. Economic analysis of the GHG emission reduction methodologies registered and approved by Korea Voluntary Emission Reduction (KVER) program was conducted. The results for waste heat recovery employed in an energy intensive pulp, paper and wood industry were reported. The emission reduction intensities were 9.7 kg $CO_2$/ton_pulp production. Net Present Value analysis showed that the GHG emission reduction was economically beneficial with an internal rate return of 60%. The results of exergy analysis indicated that the second law efficiencies of waste heat recovery system employed in KVER program were 77.3% and 53.6%. NPV decreased as the exergy decreased.
