Bolivian tuber species like potato (Solanum tuberosum), native potato (Solanum sp), Oca (Oxalis tuberosa Molina), Olluco (Ullucus tuberosus Caldas), and Isaño (Tropaeolum turosum Ruíz & Pav.) hold extraordinary nutritional value and cultural significance, particularly within the Andean region. This study examined the mineral composition of Bolivian tuber species as an essential step toward understanding their nutritional significance and potential contributions to addressing dietary deficiencies. The research involved detailed analysis of diverse tuber cultivars, uncovering distinct mineral profiles across species. Native potato shows high levels of nitrogen (N), potassium (K), phosphorus (P), and magnesium (Mg) levels, alongside moderate micronutrients like iron (Fe) and zinc (Zn). Commercial potatoes exhibited prominence in N, P, and K, with moderate Fe, Zn, and manganese (Mn) levels. Oca, Isaño, and Papa Lisa displayed unique mineral concentrations, offering potential nutritional benefits. Intricate correlations and significant variances among elements highlighted the diverse mineral compositions among these tuber species. Multivariate analyses emphasized distinct mineral profiles unique to each species, revealing significant compositions of isaño and papa lisa's. The Multitrait Genotype- Ideotype Distance Index (MGIDI) identified isaño jaspeado, isaño and an unnamed native potato, AXT2, as promising ideotypes due to their exceptional mineral compositions. These findings provide comprehensive insights into Bolivian tuber species' various mineral compositions, underscoring their nutritional significance and potential in targeted breeding for improved dietary support and enhanced food security.

목적 : 소음으로 인한 스트레스가 다양한 시기능에 미치는 영향에 대해 알아보고자 하였다. 방법 : 안과적 질환, 수술이력 및 안구운동에 이상이 없는 젊은 성인 60명(23.12±1.26세)을 대상으로 하였으며 소음에 노출되기 전, 후로 지각된 스트레스 척도, 최대조절력, 조절반응량, 원-근거리 사위량, 비침습적 눈물 막 파괴시간의 변화를 관찰하였다. 결과 : 소음 스트레스에 노출이 된 후에는 지각된 스트레스 척도는 증가하였다. 푸쉬업 및 마이너스렌즈 부가 법으로 측정된 최대조절력과 조절반응량은 감소하였고, NITBUT 역시 감소하였으며, 원-근거리 사위량은 증가하는 경향을 나타내었다. 결론 : 본 연구의 결과를 통해 소음 스트레스는 시기능에 다양한 형태로 영향을 미치고 있다고 볼 수 있으며, 굴절검사 및 시기능 평가 시 주변 환경에 의한 소음 스트레스가 작용하지 않도록 검사실 환경을 구성하는 것이 중요할 것이라 사료된다.

This study was undertaken to investigate meal pattern, nutrition knowledge and food preference of 438 rural middle school students living in ChunNam area. As far as nutrition knowledge is concerned, most subjects did not answer correctly on the items of basic five food groups, animal fat and vegetable oil, empty source of soft drink, nutrient requirement and water's role in energy metabolism. However they responded well on the item of iron deficiency and dietary source of Ca. Male students were significantly better in the answering the items of dietary source of energy and nutrient requirement than females, while female students were significantly better on the items of water's role in energy metabolism related to obesity. Generally the respondents did neither consume oil often nor consider consumption of salty food. Furthermore, only 38.6% of subjects drink milk daily in spite of understanding dietary source of Ca, which suggested that they should incorporate nutrition knowledge into dietary behavior. The preferred foods for most subjects were fruit, kimbab and ice cream. Contrastingly the food that they did not prefer was fermented vegetable probably due to strong flavor.
