School gardens are known to be effective for increasing vegetable consumption in children. This study was carried out to examine the perception of garden program leaders for actual conditions and barriers to promote school gardens according to their sense of dedication. The 49 garden program leaders at schools and child care centers in Pocheon city were surveyed and grouped into two groups: dedicated (57.1%) and less dedicated (42.9%) as program leaders. Compared to dedicated leaders, leaders in the less dedicated group less advocated promotion of school gardens (P<0.001) and were less willing to attend training for school garden (P<0.01), despite less experience as program leaders (P<0.01) and past training (P<0.05). Moreover, leaders in the less dedicated group less acknowledged the educational results of school garden in every aspect (P<0.001, respectively), less perceived support from parents and colleagues (P<0.05, respectively), and less used garden produce in more active activities such as donation and literature (P<0.05, respectively), compared to the dedicated group. The most answered barrier against the promotion of school gardens was work burden, followed by manpower shortage, shortage of technique, knowledge, and information, and time shortage. The results of this study provide evidence that developing strategies is needed to make more teachers and child care providers more dedicated as garden program leaders.

BACKGROUND/OBJECTIVES: Hypertension is the major risk factor for cardiovascular disease, a leading cause of deaths in Korea. The objective of this study was to evaluate the effect of a nutrition education in reducing sodium intake and increasing potassium intake in hypertensive adults. SUBJECTS/METHODS: Subjects who participated in this study were 88 adults (28 males and 60 females) who were pre-hypertension or untreated hypertensive patients aged ≥ 30 yrs in Gyeonggi Province, Korea. These subjects were divided into 2 groups: a lowsodium education (LS) group and a low-sodium high-potassium education (LSHP) group. Nutrition education of 3 sessions for 12 weeks was conducted. Blood pressure, blood and urine components, nutrient intake, and dietary behavior were compared between the two education groups. RESULT: Blood pressure was decreased in both groups after the nutrition education (P < 0.05). In the LSHP group, levels of blood glucose (P < 0.05), total cholesterol (P < 0.01), and lowdensity lipoprotein-cholesterol (P < 0.05) were decreased after the program completion. Sodium intake was decreased in both groups after the nutrition education (P < 0.05). However, Na/K ratio was only decreased in the LS group (P < 0.05). Intake frequency of fish & shellfish was only significantly reduced in the LS group (P < 0.05), while intake frequencies of cooked rice, noodles & dumplings, breads & snacks, stew, kimchi, and fish & shellfish were reduced in the LSHP group (P < 0.05). Total score of dietary behavior appeared to be effectively decreased in both groups after the education program (P < 0.001). CONCLUSIONS: This education for reducing sodium intake was effective in reducing blood pressure and sodium intake. The education for enhancing potassium intake resulted in positive changes in blood glucose and serum cholesterol levels.

Objectives: The purpose of the study is to investigate the factors influencing on self-esteem, major satisfaction, and career identity. Methods: A self-reported questionnaire was filled out by 389 dental hygiene students in three colleges located in Metropolitan area. The questionnaire consisted of 5 questions of general characteristics, 10 questions of self-efficacy, 18 questions of major satisfaction, and 13 questions of career identity by Likert 5 scale. Cronbach's alpha was 0.92 in self-efficacy, 0.90 in major satisfaction, and 0.88 in career identity in the previous studies. Cronbach's alpha in this study was 0.911 in major satisfaction, 0.840 in self-efficacy, and 0.8090 in career identity. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, and stepwise multiple regressions. Results: The score was 3.47 in self-esteem, 3.79 in major satisfaction, and 3.03 in career identity. There were significant differences in self-esteem and major satisfaction based on grade, motivation for entering college, and clinical practice satisfaction. In case of career identity, there were significant differences based on characteristics, motivation for college choice, and clinical practice satisfaction. There was a positive correlation between negative self-esteem, positive self-esteem, general satisfaction, awareness satisfaction, curricula satisfaction, interpersonal relation satisfaction, and career identity. The influencing factors on career identity were aptitude, interest, self-esteem, and major satisfaction in order(p<0.001). Conclusions: The career identity is closely related to self-esteem and major satisfaction. It is desirable to open a variety of education courses and to develop systematic and practical programs to the students in order to improve the career identity.

The purpose of this study is to analyze the differences in foot type of female college students according to academic major in both feet. The subjects for this study were 216 female students who took liberal arts classes in Seoul. Dependent variables were students' field of study -specifically whether or not they majored in physical education. Analysis of students' foot type and Malalignment Syndrome were measured using Resting Calcaneous Stance Position (RCSP). There were five categories for RCSP angle: Severe Pes Planus (< $-5^{\circ}$), Pes Planus ($-3^{\circ}{\sim}-4^{\circ}$), Pes Rectus (${\pm}2^{\circ}$), Pes Cavus ($+3^{\circ}{\sim}+4^{\circ}$), Severe Pes Cavus (> $+5^{\circ}$). ${\chi}^2$ analysis was used for statistical analysis. RCSP for all subjects (432 feet) occurred at the following frequency: Pes Planus(43.9%), Pes Rectus(43.8%), and Pes Cavus(12.3%). These levels were different for physical education majors, with Pes Planus at 42.6%, Pes Rectus at 49.4%, and Pes Cavusat 8.0%. Non-physical education majors exhibited Pes Planus at 45.0%, Pes Rectus at 39.9%, and Pes Cavus at 15.1%. 15.3% (33 subjects) of all students had Malalignment Syndrome. In conclusion, 56.2% of female college students had a foot deformity. There was nearly four times more Pes Planus than Pes Cavus. According to these results, exercise can be prescribed to alleviate foot deformities, especially supination. Severe pronation and supination problems appeared less amongst students not majoring in physical education. Thus, although exercise might be one cause of foot deformity, it can also help resolve problems with over-supination. Further study will be needed to understand and resolve the specific mechanism of over-supination.

The purpose of this study is to compare by learner groups(K-12, geology-related majoring students, science teachers) how geologic fieldwork education cases in domestic and foreign papers for recent 20 years reflect the elements of inquiry in field geology. The total number of analyzed cases is 53(58 for double counting), and the analysis was conducted on the elements of inquiry in field geology and their sub-element. As a result, there was a clear difference between the cases of geologic fieldwork education for K-12 and college students majoring in geology-related disciplines, in the way of reflecting elements of inquiry in field geology. Because most of K-12 target fieldworks were designed based on the curriculum, it mainly included 2-3 elements of observations, representations, and/or abductive reasoning. On the other hand, because fieldworks for geology-related major students aim to train geologic experts, it diversely contained four or five of the elements of inquiry in field geology, including spatial thinking and diachronic thinking in a high proportion, and also frequently used activities that require specialized skills such as geological mapping. Fieldworks for science teachers were found to have mixed features of K-12 and geology-related major students. Considering the diversity of included inquiry elements, similarities with the activities performed by geologists, and the autonomy of learners, it was analyzed that geologic fieldwork for geology-related major students was more close to authentic geologic inquiry than fieldwork for others. Based on the results of this study, we suggested implications for improving geological fieldwork as authentic science inquiry.

Background: Aerobic cellular respiration provides chemical energy, adenosine triphosphate (ATP), to maintain multiple cellular functions. Sirtuin 1 (SIRT1) can deacetylate peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) to promote mitochondrial biosynthesis. Targeting energy metabolism is a potential strategy for the prevention and treatment of various diseases, such as cardiac and neurological disorders. Ginsenosides, one of the major bioactive constituents of Panax ginseng, have been extensively used due to their diverse beneficial effects on healthy subjects and patients with different diseases. However, the underlying molecular mechanisms of total ginsenosides (GS) on energy metabolism remain unclear. Methods: In this study, oxygen consumption rate, ATP production, mitochondrial biosynthesis, glucose metabolism, and SIRT1-PGC-1α pathways in untreated and GS-treated different cells, fly, and mouse models were investigated. Results: GS pretreatment enhanced mitochondrial respiration capacity and ATP production in aerobic respiration-dominated cardiomyocytes and neurons, and promoted tricarboxylic acid metabolism in cardiomyocytes. Moreover, GS clearly enhanced NAD⁺-dependent SIRT1 activation to increase mitochondrial biosynthesis in cardiomyocytes and neurons, which was completely abrogated by nicotinamide. Importantly, ginsenoside monomers, such as Rg1, Re, Rf, Rb1, Rc, Rh1, Rb2, and Rb3, were found to activate SIRT1 and promote energy metabolism. Conclusion: This study may provide new insights into the extensive application of ginseng for cardiac and neurological protection in healthy subjects and patients.

This study set out to investigate the challenges to science teacher's teaching practices in the Anglophone sub-system of education in Cameroon secondary schools. A sample of 331 of these teachers was selected using the purposive sampling method. Data was collected by use of a questionnaire and was subjected to inferential analysis. The major findings from the multiple regression were challenges associated with the size and management of a science class have an effect on the teaching practices of a science teacher. However, challenges with availability of instructional resources did not have an effect on science teaching practices. Recommendations to solve the identified drawbacks include the provision of more classrooms to accommodate the ever growing population of students and the organization of many seminars through which teachers could be educated on how to handle classroom problems and improvise when necessary.
