OBJECTIVES ‘Ocean healing’ refers to treatments using seawater, seaweed, mud, sand, and all substances coming from the sea used for curative and preventative purposes. Previous studies have been supported the use of seawater to therapy in improving physical and mental health. However, the clinical effects of ocean healing program using leisure-sports remain unknown. Therefore, we investigated the effect of the ocean healing program using a stand-up paddle board (SUP) on body composition and dynamic balance in middle-aged women. METHODS Thirty women aged ≥30 years participated for this study and were randomly classified into SUP group (N=15, mean age: 50.0±13.5 years) and control group (N=15, mean age: 52.0±12.6 years). Body weight, body mass index, %body fat, skeletal muscle mass, and skeletal muscle index were measured using InBody. We also conducted the Y-balance test to measure the dynamic balance ability. Participants in the intervention group performed the SUP program 3 times a week for 60 min, and the total intervention period was 10 weeks. RESULTS In the intervention group, 13 women completed the 10-week intervention. Body weight (P=0.004) and %body fat (P=0.002) was significantly decreased in the SUP group after intervention. Moreover, we found that skeletal muscle mass was increased in SUP group (P=0.029) but not in control group. Compared to the control group, the score of Y-balance test of the intervention group were significantly improved (baseline: 85.6±7.6 vs post: 96.2±5.4, P<0.001). CONCLUSIONS On trial completion the primary outcome (body weight, %body fat, and skeletal muscle mass) was significantly improved compared with control group. We also found improved dynamic balance in the SUP group after 10 weeks intervention. Our findings suggest that implementation of an ocean healing program is an effective intervention to enhance body composition and dynamic balance in middle-aged women.

This study was to investigate the occurrence patterns of paddy weeds, their resistance levels to an ALS inhibiting herbicide, and to estimate the areas of resistance in these paddy fields. We used soil collected from 358 paddy fields of Jeonnam province in 2017. Based on their life cycles, weeds were 96% annuals and 4% perennial. Additionally, according to morphological classification, 59% were broad leaves, 28% were sedges and 13% were grasses. Different areas within Jeonnam province contained different numbers and occurrence rates of weed species. However, generally, we observed Lindernia dubia var. dubia, Monochoria vaginalis var. plantaginea, Ludwigia prostrata, L. procumbens, Cyperus difformis, Scirpus juncoides, Eleocharis Kuroguwai, Echinochloa oryzoides, and E. crus-galli var. echinata. We also observed seven weeds resistant to an ALS inhibiting herbicide. They were M. vaginalis, S. juncoides, C. difformis, L. dubia, Ludwigia prostrata, E. oryzoides, and E. crus-galli var. echinata. Although there were differences in the number and occurrence rate of resistant weed species to an ALS inhibiting herbicide among areas in Jeonnam province, the M. vaginalis, C. difformis, and S. juncoides occurred in 23 cities and counties in Jeonnam including Gwangju metropolitan city. Based on the rates (52%) of resistant occurrence to an ALS inhibiting herbicide in Jeonnam province, the area of weed resistant paddy fields was estimated to be 91,543 ha. 본 연구는 토양검정법을 이용하여 전라남도 지역 논에서 발생되고 있는 잡초발생 양상과 ALS 저해제 제초제 저항성 여부 검증 및 저항성 잡초 발생 논면적을 예측하고자 수행하였다. 2017년 전남지역 358 필지에서 채취한 토양에 발생한 잡초의 경우 생활사별로 분류한 경우 일년생 96.1%와 다년생 3.9% 발생하였고, 형태적으로 분류한 경우 광엽잡초 59.0%, 사초과 28.3%, 화본과 12.7% 순으로 발생하였다. 비록 전남에서도 시 군별 논잡초 발생 초종수와 초종별 발생율에 차이가 있으나 미국외풀, 물달개비, 여뀌바늘, 밭뚝외풀, 알방동사니, 올챙이고랭이, 올방개, 논피, 물피 등이 발생하였다. 또한 전남지역에서는 ALS 저해제 제초제 저항성 논잡초 물달개비, 올챙이고랭이, 알방동사니, 미국외풀, 여뀌바늘, 물피, 논피 7초종이 발생하였다. 비록 전남 시 군별 ALS 저해제 제초제 저항성 잡초 초종수와 발생율은 다르나 이중 물달개비, 알방동사니, 올챙이고랭이는 광주광역시를 비롯한 전남 23개 시 군에서 발생하였다. 전남지역의 ALS 저해제 저항성 발생율(51.5%)에 기초한 저항성 논잡초 발생 논면적는 91,543 ha로 평가되었다. 따라서 이러한 정보를 활용하여 제초제 저항성 논잡초 효율적 관리 방안을 수립할 수 있을 것으로 판단된다.

Since 1993, vivax malaria has been recognized as a public health burden in Korea. Despite of pan-governmental malaria-control efforts and the dramatic reduction in the burden of this disease over the last 10 years, vivax malaria has not been well controlled and has remained continuously endemic. We focused interviewed and examined the charts of 28 confirmed vivax malaria patients given malarial therapy for whom daily records were kept from Gimpo-si, Gyeonggi-do of Korea. Various epidemiological characteristics of vivax malaria, including the incubation period, medication used, and recurrence, and an evaluation of the parasitic characteristics from the focused interviews of patients from this region are described here. Most of the participants indicated the 3 most common symptoms of malaria (headache, chills and fever). Of the 28 cases, 2 experienced a second attack and there were 17 and 11 cases with short- and long-term incubation periods, respectively, yielding a short-term to long-term ratio of 1.5. Based on the parasitemia stages, most of the participants were tested at 5 to 7 days (11 cases) and 7 to 15 days (11 cases) after initial wave of asexual parasites. In conclusion, public health authorities should consider developing management measures to decrease the time lag for diagnosis and drafting unified and robust guidelines for drug use for malaria and drawing up unified and robust guidelines on the use of medication for malaria. It also suggests that routine monitoring, surveillance, and precise medical surveys in high-risk vivax malaria endemic areas are pivotal to controlling this persistent public disease and finally eliminating it from Korea.
