  • Purpose: Since the food wastewater contains a high concentration of nitrogen, it is very important to find a way to efficiently remove it. Research design, data and methodology: A total of four experiments were conducted under different conditions to remove ammonia nitrogen present in the food wastewater. The experiment was designed by adding sodium hypochlorite to the raw food wastewater and varying conditions such as pH control, aeration/precipitation, and stirring. Results: The ammonia nitrogen removal rate in Experiment 1 was about 12% (sodium hypochlorite added), ammonia nitrogen increased about 4.7% in Experiment 2 (sodium hypochlorite added after aeration/precipitation in a bioreaction tank, stirring), and decreased about 52.5% (sodium hypochlorite added after controlling and stirring). Conclusions: When the concentration of sodium hypochlorite was high, ammonia nitrogen was best removed, and the pH was adjusted to 12, and sodium hypochlorite was added after stirring, and the removal was the second best. If the method of this study is further studied and developed, it can be basic data for ammonia nitrogen removal in the future.

  • Purpose: High concentrations of nitrogen exist in food wastewater, and when nitrogen is not properly treated and discharged, it can cause eutrophication in the aquatic ecosystem. Research design, data and methodology: In order to remove nitrogen using sodium hypochlorite, the BNCR tank was designed and installed in the step behind the biological treatment tank, and the data of pH, TOC, and T-N were collected after about a month of demonstration. Results: As a result of operating the BNCR tank, total nitrogen decreased by about 83% on average. The total nitrogen in the second sedimentation tank before going through the BNCR tank must be removed and finally discharged after nitrogen is removed above the legal standard of 60 mg/L. Conclusions: If BNCR tank is added to the process currently applied to nitrogen removal and operated, ammonia nitrogen can be removed more efficiently. However, the disadvantage is that nitric acid nitrogen and nitric acid nitrogen cannot be removed. If these disadvantages are supplemented and optimized in the future, it will be helpful for workplaces that are having difficulty removing nitrogen.

  • Purpose: Since 2013, marine dumping of wastewater has been banned, and research on eco-friendly and efficient land treatment has emerged. This study compared and tested changes in biogas production and anaerobic process efficiency depending on whether or not enzyme pretreatment was performed during anaerobic digestion from single-phase and two-phase to medium-temperature. Research design, data and methodology: The total sugar, direct sugar, pH, and acidity before and after fermentation were analyzed by G/C by anaerobic fermentation of the liquor wastewater, food wastewater 1, and food wastewater 2 at 30℃ for 67 hours, and the amount of methane gas generated was analyzed by balloon volume. Results: It was found that stable organic acid concentration and pH were found in the enzyme-treated food wastewater 2, and the amount of methane gas generated was also increased. Conclusions: When anaerobic digestion of the liquor wastewater and the food wastewater together, the performance of enzyme pretreatment resulted in increased digestive efficiency. It will be the basic data that can contribute to carbon neutrality and greenhouse gas reduction by increasing the production of biogas.

  • A holistic approach to diabetes considers patient preferences, emotional health, living conditions, and other contextual factors, in addition to medication selection. Human and social factors influence treatment adherence and clinical outcomes. Social issues, cost of care, out-of-pocket expenses, pill burden (number and frequency), and injectable drugs such as insulin, can affect adherence. Clinicians can ask about these contextual factors when discussing treatment options with patients. Patients' emotional health can also affect diabetes self-care. Social stressors such as family issues may impair self-care behaviors. Diabetes can also lead to emotional stress. Diabetes distress correlates with worse glycemic control and lower overall well-being. Patient-centered communication can build the foundation of a trusting relationship with the clinician. Respect for patient preferences and fears can build trust. Relevant communication skills include asking open-ended questions, expressing empathy, active listening, and exploring the patient's perspective. Glycemic goals must be personalized based on frailty, the risk of hypoglycemia, and healthy life expectancy. Lifestyle counseling requires a nonjudgmental approach and tactfulness. The art of diabetes care rests on clinicians perceiving a patient's emotional state. Tailoring the level of advice and diabetes targets based on a patient's personal and contextual factors requires mindfulness by clinicians.

  • Objectives: Since Korean traditional medicine has an integrative perspective by its nature, the patients' psychological and physical problems in a Korean traditional clinic may be resolved through a more integrative approach. The purpose of this study was to describe the latent characteristics of psychological health of child outpatients and their parents visiting Korean traditional clinic with physical complaints and was to propose an alternative curriculum to meet their needs based on their psychological and physical aspects. Methods: Subjects studied consisted of 100 outpatients (59 boys, 41 girls, mean age 55 months, age range 18 to 83 months) and their parents. Behavior characteristics for children were measured by Korean version of Child Behavior Checklist for Ages 1.5-5 (CBCL1.5-5) while parenting stress, depression, and anxiety for parent were measured by Korean-Parenting Stress Index-Short Form (K-PSI-SF), Center for Epidemiologic Studies Depression Scale (CES-D) and State-Trait Anxiety Inventory (STAI), respectively. The data of subjects were compared to those of standardized groups and then were compared according to child's gender within sample. Results: Child participants were reported to have significantly higher scores of all CBCL 1.5-5 subscales than the standardized group. When compared, no differences of K-PSI-SF, CES-D, and STAI was found between parents of participants and the standardized groups. However, parents of child participants with at-risk psychological problems showed significantly higher scores of all parenting stress subscales than those of all child participants. In addition, the mothers of boy participants demonstrated significantly higher anxiety, depression and parenting stress than those of girl participants irrespective of psychological severity. Conclusions: We discussed the implication of these results in clinical situation and make recommendations for curriculum of psychiatry and pediatrics with the aim of improving proper diagnosis, consulting and treatment.

  • The aim of this study was to evaluate the effects of Jowiseungcheongtang compared with St. John's wort in the chronic mild stress(CMS) animal model of depression. Wistar rats were used for this study. The subjects were divided into 4 groups (Naive group: without CMS procedure, CMS-vehicle: water was administered during CMS procedure, CMS-Jowiseungcheongtang: Jowiseungcheongtang was administered after 5 weeks of CMS procedure, CMS-St. John's wort: St. John's wort was administered after 5 weeks of CMS procedure) During 9 weeks of CMS procedure, The change of the consumption of sucrose and the changes of weights were measured. After CMS procedure, Morris water maze test, open field test, elevated plus maze test and Western blotting were measured. The results were as follows. 1. The consumption of sucrose solution was significantly reversed in Jowiseungcheongtang group and relatively reversed in St. John's Wort group at 7 week. 2. In open field test, Neither Jowiseungcheongtang nor St. John's wort group showed statistically significant change of exploratory activity. In EPM test, St. John's Wort group showed significant decrease of total arm entry in comparison with Naive group. And Jowiseungcheongtang group was showed no significant change. 3. In Morris water maze test, St. John's Wort group showed significant increase in escape latency of the last Morris water maze trial. And in water maze probe test, there was no significant change. 4. St. John's Wort group showed relative increase in LP1 division of 5HT1A receptor compared with Naive group. Both St. John's Wort and Jowiseungcheongtang group showed relative increase in P2 division of GluRl compared with Naive group. These results suggest that Jowiseungcheongtang is as effective as St. John's Wort in the treatment of depression.

  • The current study aimed to develop and evaluate the effectiveness of a group coaching program to improve college students' career exploration behaviors based on the self-affirmation theory. Participants were undergraduate students at a University in Seoul and volunteered in the program during the break. The group coaching program was conducted twice a week during three weeks, a total of six times, and each session lasted 2 to 2.5 hours. In this study, the effect of self-affirmation embedded in the group coaching program on various psychological variables and college students' career exploration behaviors were examined. A mixed-randomized analysis was conducted to compare the pre, post, and follow-up tests of the experimental, comparison, and no-treatment control groups, each consisting of 18 participants. The results showed that participants in the experimental group coaching condition showed more significant improvements in psychological resources, career self-efficacy, openness, problem-focused coping, and career exploration behaviors compared to the comparison and control groups, and these results were maintained even after the program ended. The implications of this study for coaching theory and practice, as well as limitations and future research directions, were discussed.

  • Clinical neuropsychology which belongs to the necuroscience field is concerned with relationship between human behaviors and the brain structure. Clinical neuropsychology has grown to be a specialized separate field within psychology over the last twenty years. Clinical neuropsychology offers an objective methodology to consider the mind-body interaction and evaluate the behavioral consequences and functional deficits associated with brain lesions. Clinical neuropsychological assessment is composed of cognitive, perceptual, motor and emotional function through various neuropsychological examinations such as Halsted-Reitan and Luria-Nebraska batteries, and computerized neuropsychological test such as PCIS Vienna Test System and Stim. The goals of neuropsychological evaluation are to identify of neuropsychological dysfuncitions, to develop execute and monitor treatment plans, and to make rehabilitation programs. Recently, the neuropsychiatric patients are increasing in number and 15-20% of acute psychiatric patients suffer from organic mental problems. Moreover, clinical neuropsychology has an increasingly important role in both neurobehavioral foundation and clinical application. So, psychiatrists must play a major role in the development of clinical neuropsychology in psychiatry.

  • Initial science teacher education in Hong Kong is provided by the Post-graduate Diploma in Education Programme (PGDE) for both pre-service and in-service secondary school teachers. This programme includes a balanced treatment of subject curriculum and teaching in science, general pedagogical knowledge and skills, educational psychology and school administration. The science courses in this programme also have some units that equip science teachers with the knowledge and skills that are essential for teaching a science curriculum that emphasises conceptual change and understanding of the nature and methods of science. This emphasis is illustrated by two studies: (1) Developing a conceptual change model of instruction in Biology teachers, and (2) Constructing understanding of the nature and methods of science.
