This study examined the acoustic characteristics in women diver's Soombijil sound. A total of 18 women divers was attended this study. Acoustic analysis was performed via Praat. Soombijil sound were classified into three types as pitch variations in beginning, middle, and ending part. Type I showed increasing-decreasing-flat. Type II was identified by the shape of flat-flat-increasing. The shape of type III showed increasing-decreasing-increasing. Duration of Soombijil sound was mean 1.48 sec. The range of frequency was 1591.54 ${\sim}$ 4477.13 Hz. FFT analysis showed that frequencies were concentrated 500${\sim}$2000 Hz. Type I and II showed two peaks at 500 Hz and 1500${\sim}$2000 Hz. Type III has one peak below 500 Hz.

Canavanine content of the cotyledons of Canavalia lineata decreased gradually during germination and growth of seedlings but continued to increase in roots and leaves. After abscission of cotyledons, canavanine content of leaves depleted competely. The activity of canavanase could be detected in leaves and roots, but not in cotyledons. High arginase activity was observed in the cotyledons of seeds at the earlyimbibition period. During the growth of seedlings, cotyledonary canavanine appeared to be transported to the growing of seedlings where it could be utilized through nitrogen metabolic pathways. In crude cell-free extracts of leaves, maximum activities of canavanase or arginase appeared in 30mM Tris-HCl buffer (pH 9.0) or 30mM NaHCO3 buffer (pH 10.0), respectively. The activities of these two enzymes differed from each other when treated with Co2+ or Mn2+. These results support the idea that canavanase and arginase might be different enzymes.

The root nodule of Canavalia lineta was classified as a determinate nodule and the symbiont as a Rhizobium-bacteriod based on their morphological characteristics. Isolated encosymbiont was similar both to R. leguminosarum and R. meliloti in its peritrichous arrangement of flagella and some of the physiological characteristics. Compared to control plants, Canavalia seedlings inoculated with the isolate grew normally due to induced root nodules, confirming isolate's infectivity and effectivity. Characteristics of the reisolated endosymbiont from induced root nodule were identical to those of the first isolate, indicating the nodules were induced by the first isolate. From these results, it was confirmed that Rhizobium strain isolated from the root nodules of Canavalia lineata was a real symbiont, and was named Rhizobium sp. SNU003.

제주는 2002년 유네스코 생물권보존지역 지정을 시점으로 15년간 총 5개의 유네스코 등재와 하나의 UNFAO 세계농업유산(GIAHS)에 등재되었다. 제주가 보유한 5가지 유네스코 타이틀은 생물권보존지역(2002), 세계자연유산(2007년), 칠머리당굿 무형문화유산(2009년), 세계지질공원(2010년), 해녀무형문화유산(2016년) 이며, UNFAO의 등재는 세계농업유산 제주밭담(2014년)이다. 이런 세계적 수준의 등재는 고도의 인식과 환경 보호의 가치를 상징하며 더불어 제주방문 관광객을 증가시키고 있다. 그러나, 지금까지 이러한 세계적 유산의 중요성에 비해 제주도민과 방문객 대상의 인식 측정 연구는 매우 부족한 것이 사실이다. 이에 본 연구는 제주도민과 관광객을 대상으로 제주의 세계적인 유산에 대한 인식과 인식 경로, 그리고 로고의 인식 여부와 세계적인 유산 등재에 따른 영향인식에 대해 설문조사를 실시하였다. 그 결과, 유네스코 세계자연유산과 가장 최근에 등재된 해녀 무형문화유산에 대한 제주도민과 관광객의 인식 수준이 가장 높았으며 밭담과 제주 칠머리당 영등굿에 대한 인식 수준은 상대적으로 낮은 것으로 나타났다. 세계유산 로고에 대한 인식 여부에서는 유네스코 로고에 대한 노출이 가장 높은 것으로 나타났다. 이러한 결과를 바탕으로 제주가 보유하고 있는 세계적 자연과 유산의 지속적 보호와 더불어 올바른 홍보 방안의 모색이 필요하다.

Scavenging effects of DPPH radical and hydroxyl radical, inhibition of linoleic acid oxidation, inhibition of NO synthesis and iNOS expression were tested with extracts and chromatographic subfractions of Canavalia lineata obtained at Jeju island. Chloroform extract and its subfractions gave moderate effects on scavenging DPPH radical and hydroxyl radical, They also inhibited linoleic acid oxidation, and NO synthesis. Inhibition of NO synthesis resulted from the repression of iNOS gene expression. Ethyl acetate extract and its subfractions showed excellent effects on scavenging DPPH radical and hydroxyl radical, while they were cytotoxic.

The content of canavanine was measured and analyzed in leaves, roots and xylem exudate of Canavalia lneata. In non-nodulated plants, the cotyledons were removed after a week of sowing and the plants were grown for 3 weeks. The quantity of canavanine measured by canavanine specific-PCAF colorimetric assay was 9-10 $\mu$mol/g fresh wt. in leaves, 5-6 $\mu$mol/g fresh wt. in roots, and 0.3-0.5 $\mu$mol/ml in xylem exudate. When free amino acids of leaves, roots, and xylem exudate were analysed by HPLC, the relative proportion of asparagine plus glycine was the highest and canavanine was high secondarily. And the relative proportion of canavanine among total free amino acids was 30-35% in leaves and roots, and 12-13% in xylem exudate. In non-nodulated plants grown for 8 weeks, the canavanine content of each part was similar to that of 3-week-old plants. By the formation of nodules, the canavanine content of leaves, roots, xylem exudate, and nodules decreased apparently. In xylem exduate, the nitrogenous compounds were also analyzed. The relative contents of NO3-, free amino acids, and ureides(allantoin and allantoic acid) were 60-80%, 20-30%, and 5%, respectively. From these results, it can be assumed that canavanine is synthesized in the root of plant and nodulation affects the canavanine content. It is obvious that canavanine is considered one of the reduced-N forms transported via xylem.

The constituents and proportions of non-protein free amino acids including canavanine were measured in roots and leaves of legumes, Robinia pseudo-acacia L., Wistaria floribunda L., and Canavalia lineata L. by using high performance liquid chromatography during dormant and fertilizing seasons. in all the three plant species, asparagine was the most abundant amino acid occurring 30％ of total free amino acids, and canavanine was the second most abundant amino acid contributing 10％ of total free amino acids throughout dormant and fertilizing seasons. In dormant season, roots contained 2 to 3 folds of free amino acids including canavanine and asparagine compared to those in fertilizing season. When proportions of asparagine and canavanine to total gree amino acids in various parts of C. lineata were examined in fertilizinng season, the level of asparagine was the highest in roots while that of canavanine was in seeds. On the basis of these results, it is assumed that canavanine appears and functions as a nitrogen-storing compound in roots and leaves throughout the whole life cycle of the investigated plants.

Purpose: To investigate the subjective health and health-related quality of life (HRQoL) in Haenyo. Methods: Subjects were 100 elderly Haenyo in Jeju island who belonged to a fishing-village society. Main variables were activities of daily living (ADL), instrumental ADL (IADL), the HRQoL, subjective health, and depression. Subjective health and differences of HRQoL by variables were analyzed by t-test or ANOVA using IBM SPSS Statistics 23. Hierarchical multiple regression was executed to examine the effects of the major factors on the quality of life. Results: The mean age was 69.9 years, the mean period for diving career was 51.5 years, and work hours per month were 37.8. Comorbidity of diseases was 2.74, and the common health problems were osteoporosis and headache/dizziness. HRQoL was significantly different by age (F=4.52, p=.013), education (F=6.10, p=.003), muljil work years (F=3.93, p=.050), depression (t=-3.04, p=.030), subjective health state (F=30.62, p<.01), and degenerative arthritis (F=-2.38, p=.019). In the final model by hierarchical multiple regression, ADL/IADL (${\beta}=.41$, p<.001), depression (${\beta}=-.29$, p<.001), and subjective health (${\beta}=.43{\sim}.51$, p<.001) were significant and explained 63.5% of the total variance of HRQoL. Conclusion: Haenyo have specific health problems different from those of elderly women in general. ADL/IADL, depression and subjective health affected their HRQoL. It is clear that Haenyos' health problems need further study to improve their health.

The purpose of this study was to investigate the nutritional intake and dietary habits of women divers in Tongyoung area and to support the guideline for the improvement of their dietary life style by a validation of a Computerized Semi-quantitative Food Frequency Questionaire. Compared to the women at Jeju Island, the Tongyoung divers showed similar heights (154.6 $\pm$ 0.8 cm), weights (53.5 $\pm$ 1.0 kg) and BMIs (23.3 $\pm$0.4) , but they showed especially high levels of body fat (33.8 $\pm$ 0.8) . Their dietary habits showed they usually skipped lunch, but ate too much food at once, which may represent the dietary habits shown by obese people. Over 40% of the divers were taking some nutritious food or complementary food for health, without realizing the efficacy of these foods. The analysis of nutritional intake showed that all of average daily nutrients intakes of those below 50 years were higher than those of the Korean RDA. In the case of those above 50 years, it was shown that the average daily nutrients intakes were also higher than those of the Korean RDA except for energy (94.5%) and calcium (82.1%) . However, some individual divers showed lower nutrients intakes than 75% of RDA for calcium, iron, Vitamin A and Vitamin B$_2$. Also, excessive intakes of phosphorous and sodium could be a dietary problem. There was no correlation between BMI or percentage of body fat and energy, CHO, protein or fat. These results can provide the nutritional information for this special community, women divers, to improve their health.
