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.

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.

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.

This study was attempted to investigate Korean women divers' nutritional status and the effect of their putting on rubber diving suits on the energy balance. For these investigations, measurements of nutrients intake, energy intake and energy consumption during diving work were performed. This study was conducted in summer and winter of 1981. Nutrition survey was carried out by interviewing each individual and the energy consumption during diving work was calculated from the extra oxygen consumption over the resting value and the change in mean body temperature in sea water. The results obtained were summarized as follows : 1) In summer, the divers' dietary intake were 2,454 Kcal for energy, 69g of protein, 16g of fat 578mg of calcium, 11mg of iron, 526 Retinol Equivalent of vitamin A, 1.1mg of thiamin, 1.3mg of riboflavin, 19mg of niacin and 50mg of ascorbic acid. These results showed that the intakes of energy, thiamin, riboflavin, niacin and ascorbic acid were higher than the Korean Recommended Dietary Allowances (RDA). Whereas in winter, the nutrients intake except iron, riboflavin, and vitamin A were higher than the RDA. 2) The energy consumption, measured by oxygen consumption and changes in body heat content, used in diving work were 260 Kcal per day in summer and 370 Kcal per day in winter. These values were about 600-700 Kcal per day lower than 1960s' 1,000 Kcal per day. The divers' energy intake were 2,454 Kcal per day in summer and 2,487 Kcal per day in winter. These data were about 550 Kcal per day lower than 1960s' intake. Since divers have worn the rubber diving suits, the energy consumption decreased as compared with the energy consumed while wearing cotton suits. And this seemed to be resulted in decreasing the energy intake. This result also showed that the balance between energy expenditure and energy intake were kept. 3) The mean subcutaneous fat thickness of divers and nondivers were 8.85 and 9.03 mm respectively. These values were as high as four times as those of 1960s'. The total body fat contents wers 25.8 percent in both diver and nondiver groups and showed an increase as high as twice as compared with 1960s' values.

The purpose of this study is to suggest a new method to develop the apparel design applied construction of traditional swimsuit wearing Jeju woman divers known as Haenyeo. Jeju Haenyeos are represented as an image of the diligent and strong woman. With such an image, they have become the symbol of Jeju women. Furthermore, Jeju Haeyeo culture will be rebranded. The Jeju woman divers wear special swimsuit (Mul-sojungii) when harvesting the various sea products. The Mul-sojungii was buttoned down the right side so that it could be easily removed. Therefore, it is to review the fashion design products for effective item applied the original or modified folding technique of Mul-sojungii. As a result, it was to develop the bolero, jump suit and dress design of Korean image using folding technique(Guljapgi) of Mul-sojungii that is one of the unique, indigenous construction of Jeju.

Sea-divers(woman) are living in coastal villages and their principal daily work is to dive into sea water in order to get sea-weeds, pearls etc. They are able to be stayed inside the water for a relatively long period and at the same time have a hard physical work during the period. Besides these works, they work also on farms and in homes in their rest time. Hwa-Jeon-Min('fire-field' farmers) are living in higher mountainous areas (plateau areas) and they burn off the ground for cultivation and obtain the crops on which they are living. Usually, they are far apart from cities and markets. The above mentioned two groups are special social groups in this country, consequently are interested in their food and nutritional habbits. The summarized surveyed results are as follows (See the Tables 1, 2, and 3). 1. In case of Sea-divers(woman): a. Staple foods are cereals, vegetables, and fishes and shell-fishes. These foods occupy 40%, 15%, and 24% respectively of all the foods intaken. b. Relatively large amount of protein and fat are intaken. Especially animal protein shows 64% of total protein intaken. c. Intake of vitamin $B_2$ is low but all other nutrients are intaken in relatively good amount. 2. In case of Hwa-Jeon-Min ('fire-field' farmers): a. Staple foods are cereals, potatoes, and vegetables. These foods occupy 61%, 19%, and 14% respectively of all the foods intaken. b. Intaken amount of animal foods is only 7 grams and this figure is only 0.1% of total foods intaken. c. Intake of animal protein is 0.4 to 0.6 grams per day and that of fats is 8 to 10 grams only. d. Intake of carbohydrate is very high. The calorie derived from the carbohydrate is 86% of total calorie intaken. e. Intakes of calcium, vitamin A, Vitamin $B_1$, Vitamin $B_2$, and niacin are low. Especially, calcium, vitamin A, and vitamin $B_2$ are deficient from their food habbits.

Rectal temperature, skin temperature and oxygen consumption were measured in five women divers during diving under two conditions a) wearing a cotton bathing suit and b) wearing a diving suit and the following results were obtained. 1. The duration of the diving period was 30 min with the cotton bathing suit whereas it was above 120 min with the diving suit. 2. The average rectal temperature fell to $34.5^{\circ}C$ after 30 min of diving with the cotton bathing suit. On the other hand, with the diving suit, immediately after submersion, the rectal temperature rose about $3^{\circ}C$ and remained at about $39^{\circ}C$ throughout the diving period of 120 min. 3. Average mean skin temperature during diving was $11^{\circ}C$ and $21^{\circ}C$ with cotton bathing suit and with the diving suit, respectively. The mean body temperature fell to $25^{\circ}C$ with the cotton bathing suit while it reached $32^{\circ}C$ with the diving suit at the end of each diving period. 4. Oxygen consumption during diving was three fold of the pre-dive level with the cotton bathing suit but it was two fold with the diving suit. 5. Total extra heat loss was 323 kcal during 120 min of diving with the diving suit. On the contrary, with the cotton bathing suit, it was 528 kcal for 30 min, These results may suggest that the prolongation of the diving period with the diving suit is primarily due to maintenance of core temperature at more or less physiological level as a result of reduction in conductive heat loss from the body surface to the water and the Preferential distribution of blood in the core area.
