한국의 해양 라이프가드들은 아직 장애인을 위한 구조 및 안전 관리를 수행할 준비가 되어있지 않다. 더욱이 대부분의 라이프가드 훈련들이 장애인 구조에 관한 정보 혹은 훈련이 제공되지 않고 있다. 본 연구의 목적은 문헌 검토를 실시하여 장애인을 위한 해양 라이프가드, 수상 안전관리와 관련하여 주요 이슈와 문제점을 찾아내는 데 있다. 데이터베이스(e.g., CINAHL Plus with Full Text, ERIC, MEDLINE, SPORTDiscus with Full Text)를 사용하여 연구논문과 해양안전과 관련한 국가/민간단체들의 문서들을 검색하였다. 사용된 검색어 혹은 키워드는 물 안전, 구조 요원, 익사 방지 등이 있었다. 주요 이슈를 파악하기 위해 수집된 문서내용을 분석(내용 분석법)을 실시하였다. 결과는 내용분석결과를 토대로 장애인 구조(rescue), 익사방지 및 수상안전과 관련된 중요한 다섯 가지 이슈들을 도출할 수 있었다.

Today, SPA fills many of the same needs as they did thousands of years ago, including relaxation, wellness and stress relief by incorporating many of the same methods embraced by the ancients such as a multitude of hydrotherapy treatments, thalassotherapy and massage therapy, one of the most widely used SPA treatments. The definition is as follows: SPA is entities devoted to enhancing overall well-being through a variety of professional services that encourage the renewal of mind, body and spirit. It was from here that the concept of modernday SPA evolved, incorporating full health and beauty services along with sport, aquatic and rest facilities. Todays SPA, a absolute concept, is being specialized and spread as fast as undefinable just in a word. Thalassotherapy, a kind of SPA therapy, contains minerals and trace elements. Born more than 4,000 years ago in ancient Egypt, thalassotherapy comes from the Greek words for thalasso(sea water) and therapeia(to heal). Thalassa was the Greek personification of the Mediterranean Sea that surrounded them and gave them so much of their sustenance. It helps to nourish, hydrate and refine skin texture and also eliminate metabolic waste and toxins in the body. Thalassotherapy is recommended for post-natal and postsurgery recovery period, chronic fatigue, circulatory problems, cellulite control and dermatological problems. It's also possible to enjoy the thalassotherapy SPA as a day guest. Be sure to try the jansu massage, given in the heated sea water pool. As a trained therapist gently whisks clients through the womb-warm water, clients can practically feel the toxins leave their body. Many women from all over the world have been kept up beautiful skin with applying thalassotherapy to their faces and bodies since long times and these days in France, they are getting great curative clinical effects from renovative and scientific technological combination. Thus thalassotherapy will be absolutely ultimate form of natural healing which can keep and recover human's health and beauty.

The purpose of this study was to determine the effects of beverage temperature and composition on weight retention and fluid balance upon voluntary drinking following exercise induced-dehydration. Eight men who were not acclimated to heat participated in four randomly ordered testing sessions. In each session, the subjects ran on a treadmill in a chamber maintained at $37^{\circ}C$ without being supplied fluids until 2% body weight reduction was reached. After termination of exercise, they recovered for 90 min under ambient air conditions and received one of the following four test beverages: $10^{\circ}C$ water (10W), $10^{\circ}C$ sports drink (10S), $26^{\circ}C$ water (26W), and $26^{\circ}C$ sports drink (26S). They consumed the beverages ad libitum. The volume of beverage consumed and body weight were measured at 30, 60, and 90 min post-recovery. Blood samples were taken before and immediately after exercise as well as at the end of recovery in order to measure plasma parameters and electrolyte concentrations. We found that mean body weight decreased by 1.8-2.0% following exercise. No differences in mean arterial pressure, plasma volume, plasma osmolality, and blood electrolytes were observed among the conditions. Total beverage volumes consumed were $1,164{\pm}388$, $1,505{\pm}614$, $948{\pm}297$, and $1,239{\pm}401$ ml for 10W, 10S, 26W, and 26S respectively ($P$ > 0.05). Weight retention at the end of recovery from dehydration was highest in 10S ($1.3{\pm}0.7kg$) compared to 10W ($0.4{\pm}0.5kg$), 26W ($0.4{\pm}0.4kg$), and ($0.6{\pm}0.4kg$) ($P$ < 0.005). Based on these results, carbohydrate/electrolyte-containing beverages at cool temperature were the most favorable for consumption and weight retention compared to plain water and moderate temperature beverages.

Dietary supplements derived from natural sources are an essential factor in optimizing athletic performance. It has been proposed that the extract of Momordica charantia (M. charantia) that is known as a bitter melon can be potentially used as a novel supplement for health promotion. This pilot study aimed to examine the effects of the M. charantia extract when administered in the form of a sports drink, and we evaluated changes in body composition and metabolic factors in tennis players after 4-week consumption of the extract. Eight male college tennis players were instructed to consume an M. charantia extract 6 times per day (3 in the morning and 3 in the afternoon, and the total daily intake was 600 ml). Collected data were analyzed using paired t-tests to examine the changes over time after consumption of the M. charantia extract. The results revealed a significant increase in the trunk muscle mass, basal metabolic rate, and daily calorie intake (p < 0.05). Levels of protein, minerals, and total body water showed an increased tendency (not statistically significant), whereas intracellular water and extracellular water showed a decreased trend. Furthermore, fat-free mass, skeletal muscle mass, and muscle mass showed an increased tendency. In conclusion, consumption of the M. charantia extract caused an increase in parameters related to protein, muscle mass, and metabolism. It seems that follow-up studies related to fatigue, inflammation, and stress hormones related to the M. charantia extract consumption would be needed.

As people have gained leisure time and become more interested in sports, various industries catering to these sports, including aquatic and underwater activities are growing. Many people are getting into scuba diving, where people can explore the sea at depths of more than 40-meters. Despite the increasing demand, there are limited studies on the sport. This study aims to provide basic research on materials suitable for developing technical scuba diving suits by analyzing several areas, such as design, material, sewing patterns, etc. The following trends were observed in all wetsuits: closure designs, ergonomic patterns, practical and functional details. Neoprene was the primary material of diving suits, and various functional materials were attached to the outer fabric or lining. The seam technique which minimized water contact and improved durability was sewing. Various techniques were also applied, such as flatlock stitching, GBS, LFS, etc. Subsequent studies shall investigate consumer preference etc. and other aspects, and continue to allow for the research and development of technical diving suits.

Wearing the right sportswear is one of the essential points in exercising, which is mainly neglected. Sportswear should be suitable for the ambient temperature and not cause more heat or cold in the athlete's body. On the other hand, increased sweating and blood circulation during exercise should not cause fatigue or heatstroke in the athlete. Nanotechnology has grown significantly in the field of producing more efficient equipment in the field of sports. The increase in demand in sports for complete sports equipment has revealed the necessity of using the highest quality materials in this sector. In the world of championship sports, a minor change in equipment can lead to significant changes in causing failure and victory. Since the sole is the most critical part of sports shoes, with the introduction of nanotechnology and nanocomposites, it is possible to help athletes rush and increase their sense of calm and satisfaction. Using nanocomposites in the soles of shoes can improve some of their characteristics, prevent the smell and sweat of shoes, and induce water repellency in these shoes. In this research, titanium dioxide (TiO₂) nanocomposite, along with cellulose, has been used to create antibacterial and hydrophobic properties in the soles of sports shoes. The synthesized nanocomposite has been synthesized using the least amount of chemicals, which shows this method's easy and cost-effective synthesis.
