  • This study assessed scuba divers' wetsuit selection criteria based on the gender, age and scuba diving commitment level along with identifying currently owned and preferred wetsuit types. Lamb and Kallal's Functional, Expressive, and Aesthetic Consumer Needs (FEA) Model was the conceptual framework used for this study. Scuba diving has seen consistent growth, worldwide, it is necessary to investigate with wetsuit needs of this consumer group. A survey of 302 active scuba divers participated in the study. Total participants included 202 male and 100 female scuba divers. Divers stated fit was the most highly rated criteria with don/doff being most problematic. Female and older divers regarded functional performance criterion greatly(p<.05). Highly committed divers regarded the functional quality (p<.01) and aesthetic/expressive features (p<.05) of the wetsuit as important and owned more wetsuits(p<.01). Gender saw differences in required sizes ranges(p<.001) and style preferences(p<.05). Results suggest gender, age, and commitment levels all impact the wetsuit selection criteria of scuba divers.

  • 본 연구에서는 무호흡으로 저수온의 해수에서 채집활동을 하는 제주 해녀의 폐기능 및 폐확산능을 측정하였으며, 동일 연령대의 일반여성과 비교한 결과는 다음과 같다. 첫째, FVC 및 FVC%는 해녀집단이 일반여성들보다 유의하게 높았다. 둘째, $FEV_1/FVC$는 일반여성과 해녀집단간 차이가 유의한 차이는 없었다. 셋째, $FEF_{25{\sim}75%}$는 두 집단 모두 정상수준이었으며, 해녀집단이 일반여성보다 유의하게 높았다. 넷째, DLCO는 해녀집단과 일반여성과 유의한 차이는 없었다. 이러한 결과는 제주해녀가 고령임에도 불구하고 장기간 무호흡 침수활동을 수행하면서 폐기관의 적응 및 발달이 된 상태임을 확인할 수 있었다. 하지만 제주해녀의 경우 계속적인 직업적 신체활동을 유지했음에도 불구하고 DLCO가 통계적으로 유의하지는 않았지만 일반여성보다 낮게 나타난 점은 폐포와 간질의 손상이 발생했을 가능성이 높기 때문에 차 후 고령의 제주해녀에 대한 계속적인 신체기능검사가 요구된다.

  • Background: Water pressure and muscle contraction may influence bone mineral density (BMD) in a positive way. However, divers experience weightlessness, which has a negative effect on BMD. The present study investigated BMD difference in normal controls and woman free-divers with vertebral fracture and with no fracture. Methods: Between January 2010 and December 2014, traditional woman divers (known as Haenyeo in Korean), and non-diving women were investigated. The study population was divided into osteoporotic vertebral fracture and non-fracture groups. The BMD of the lumbar spine and femoral neck was measured. The radiological parameters for global spinal sagittal balance were measured. Results: Thirty free-diving women and thirty-three non-diving women were enrolled in this study. The mean age of the divers was $72.1{\pm}4.7$ years and that of the controls was $72.7{\pm}4.0$ years (P = 0.61). There was no statistical difference in BMD between the divers and controls. In divers, cervical lordosis and pelvic tilt were significantly increased in the fracture subgroup compared to the non-fracture subgroup (P = 0.028 and P = 0.008, respectively). Sagittal vertical axis was statistically significantly correlated with cervical lordosis (Spearman's rho R = 0.41, P = 0.03), and pelvic tilt (Spearman's rho R = 0.46, P = 0.01) in divers. Conclusion: BMD did not differ significantly between divers and controls during their postmenopausal period. When osteoporotic spinal fractures develop, compensation mechanisms, such as increased cervical lordosis and pelvic tilt, was more evident in traditional woman divers. This may be due to the superior back muscle strength and spinal mobility of this group of women.

  • Purpose: This study aimed to investigate the level of knowledge and education regarding basic life support (BLS) among scuba divers. Methods: Data collected from 125 scuba divers in Jeju-do were subjected to frequency, t-test, ANOVA, and Chi-square analyses using the SPSS 18.0 program. Results: 42.1% of the subjects was trained BLS for more than an hour less than 4 hours, and 52.6% of the subjects was trained BLS for less than 3 months in scuba diving institutions. Statistically significant difference was observed in the competence for performing cardiopulmonary resuscitation during BLS education according to gender and age further regarding the necessity of BLS education, significant difference was observed with respect to age, job, academic background, monthly income, and participation period of scuba divers. The divers wished to learn cardiopulmonary resuscitation (72.8%), medical first aid (8.0%), and measures to be taken in cases of trauma (8.0%). The knowledge score for BLS among scuba divers was significantly different depending on the gender, age, marital status and frequency of participation. Conclusion: It is necessary to develop and implement a safety education program for scuba divers.

  • 본 연구에서는 우리는 평균 연령이 높은 제주 해녀의 경-대퇴 맥파 전도 속도와 발목-상완지표를 측정하여 찬물에서 산소의 보조 없이 채취활동을 하는 제주 해녀의 동맥 혈관의 경직도를 측정하였으며, 결과는 다음과 같다. 첫째, 경-대퇴 맥파 전도 속도는 동연령대의 일반여성보다 유의하게 낮게 나타났다. 둘째, 발목-상완지표(ABI)는 해녀와 일반여성 모두 정상범위 안에 포함되어 있었으며, 일반여성보다 해녀집단이 높은 경향을 보였다. 이러한 결과는 고령의 나이임에도 불구하고 장기간 침수활동을 통해 신체의 적응이 이미 완료된 상태로써 저온 및 높은 수압환경에 대한 적응이 완료된 신체상태이며, 아울러 높은 신체활동 수준으로 인하여 말초혈관저항이 고연령임에도 불구하고 감소되지 않았으며, 오히려 동연령 여성들보다 양호한 수준임을 확인할 수 있었다. 하지만 해녀들의 고령화는 여전히 진행되고 있는 중요한 현상이기에 동맥혈관경직도에 대한 관심과 향후의 지속적인 연구는 반드시 더 필요할 것으로 보인다.

  • 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.

  • A marine protected area (MPA) is a spatially designated section of the ocean where the biodiversity is high. Munseom MPA has a unique underwater landscape including soft coral, subtropical fish, and benthos, attracting many scuba divers. This paper intends to evaluate the willingness-to-pay (WTP) for the scuba diving management policy in the Munseom MPA. As a stated preference valuation method, a choice experiment was applied to assess divers' preferences with economic values for the policy. The attributes used in the study included zoning (temporal closure), conservation education, daily permit, soft coral area, and diving fee. We collected 333 questionnaires through online and field surveys and used 296 after excluding incomplete responses for the final data analysis. Study results show that a six-month closure, a decrease in soft coral habitat, and the diving fee were statistically significant. A positive coefficient with regard to the six-month closure variable indicates that divers preferred the policy, and the marginal willingness to pay (MWTP) was estimated to be KRW 8,637 per person per dive. The aggregate WTP of KRW 233 million was obtained by multiplying the MWTP by the number of visiting divers per year. When comparing the levels of recreation specialization, more skilled divers preferred the management option. The results of this study will help predict the priority of management measures and the levels of acceptability among divers when diving management is implemented in Korea in the future. This study suggests that marine environmental policies need to consider divers as one of the important stakeholders for marine conservation.
