在热带地区,石灰山森林(LFs)和非石灰山森林(NLFs)之间的植物通常表现出不同的分类学和功能型特征。蕨类植物是热带雨林的主要组成成分之一。然而,我们对LFs中分布的蕨类植物的形态和生理特征了解甚少。在本项研究中,我们评估了中国西南热带地区LFs和NLFs中的蕨类植物物种在7个叶片功能性状上的差异。我们测量了25种蕨类植物的叶片水分含量、形态特征(包括叶片大小、叶片厚度、气孔长度和气孔密度),以及生理特征(包括气孔导度和光合速率)。研究结果表明,与NLFs相比,LFs中蕨类植物的叶片更厚、更小,气孔密度和气孔导度更低,这可能反映了它们的水分利用策略。然而,当考虑系统发育关系时,这些差异变得不显著了,这表明系统发育保守性影响了LFs和NLFs的性状差异并最终影响了物种组成。在LFs和NLFs中共同出现的一些物种具有一定的种内性状变异,在LFs中气孔密度更低。这些发现表明,只有少数蕨类植物的水分利用策略能够同时适应LFs和NLFs,因此蕨类植物不太可能发生适应性辐射。

Mechanically aligned total knee arthroplasty (TKA) for valgus knee is considered a “challenging surgery.” Recently, the kinematic alignment (KA) method has gained attention. This study aimed to present objective clinical data, such as intraoperative balance assessment and radiographic evaluation of postoperative lower extremity alignment after TKA using the KA method for valgus deformity. Twenty-one TKA knees (mean age, 74 years;2 males, 19 females) with KA for severe valgus deformity (hip-knee-ankle-angle ≥ 10°) performed at our department in the past 3 years were included in this study. Intraoperative gap and balance measurements and postoperative radiographic evaluation were performed. A total arc of range of motion was achieved up to 98% of preoperative values at 3 weeks postoperatively. Intraoperative gap and balance were stable throughout the entire range of motion. In addition, there were no statistically significant differences in either balance or gap values at each flexion angle. KA TKA is a “simple surgery” rather than a “challenging surgery” because additional soft tissue procedures are not required, operative time is short, intraoperative and postoperative balance is very stable, and a good alignment is achieved. This procedure may relieve surgeons of the stress of TKA for valgus deformities.

The hypothesis that some children with attention-deficit hyperactivity disorder (ADHD) may show sensitivity or allergic reactions to various food items has led to the development of the oligoantigenic diet. The rationale of the diet is to eliminate certain foods from the diet in order to exclude potential allergens contained either naturally in food or in artificial ingredients with allergenic properties. The oligoantigenic diet attempts to identify individual foods to which a person might be sensitive. First， ADHD symptoms are monitored while multiple foods are excluded from the diet. Subsequently， if symptoms remit， foods are re-introduced， while observing the individual for the return of symptoms. An advantage of the oligoantigenic diet is that it can be tailored to the individual. A growing body of evidence suggests that behavioral symptoms of subgroups of children with ADHD may benefit from the elimination of certain foods. The effect sizes of an oligoantigenic diet regarding improvement of ADHD symptoms have been found to be medium to large. Available evidence suggests that the investigation of the role of food hypersensitivities in ADHD is a promising avenue worthy of further exploration. Further large-scale， randomized controlled studies including assessment of long-term outcome are therefore warranted.

Many agricultural landscapes have been formed through the interaction and co-evolution of nature and people, and represent the living landscapes shaped over time through intensive and continuous human cultivation. Terraced paddy fields are being re-evaluated to take into account the multiple functions they fill beyond only rice cultivation, particularly their contribution to the national biodiversity strategy of Japan. Since the 1990 s, terraced paddy fields have been considered a representative cultural landscape of Japan and, at the same time, multi-stakeholder conservation activities have been conducted throughout Japan to reverse the increasing abandonment of terraces. Shiroyone Senmaida is an outstanding cultural landscape and a major tourist attraction in Noto Peninsula, Ishikawa Prefecture, which was designated through an initiative by the Food and Agriculture Organization(FAO) as a Globally Important Agricultural Heritage Systems(GIAHS) pilot site in 2011. It is important to clarify tourist preference for terraced paddy field landscapes to contribute to future policy making toward improved agricultural landscape conservation. A key finding of this study is that tourists visiting toenjoy the agricultural landscape are also concerned on the sustainability of the farming methods and preferred to maintain the naturalness of the landscape. Respondents with higher educational levels and greater concern for the biological and traditional farming knowledge aspects of the rice terraces were also more inclined to favor sustainable farming practices. Tourists preferred to maintain the naturalness and rurality of the agricultural landscape, and indicated that construction of excessive tourist facilities would cause the landscape to deteriorate. It was suggested that the local community and surroundings, including rural settlements, hills, and forests, should also be conserved together with the scenic terrace.

This study aimed to clarify the amount of physical activity, lifestyle, and self-esteem of elementary school students living in Aomori Prefecture Japan. The subjects were ninety-one elementary school students in the 4th to 6th grades who live in A town. The subjects were asked to fill out a questionnaire about lifestyles and self-esteem and to wear the lifestyle-related recorder Life Coder GS® (Suzuken, Japan) for a total of four days, two weekdays and two holidays. The results showed the amount of exercise such as the number of steps taken was significantly higher on weekdays than on holidays. There was no difference by gender or classification of obesity. In addition, when they go to school on foot, the number of steps and fast walking time was significantly higher than when using the bus. Screen times of holidays were significantly longer than those of weekdays. The number of steps on holidays was negatively correlated with screen time, and positively correlated with the factor of “self-assertion/self-determination” of self-esteem scale. Health promotion is needed so that the entire community, including family and friends, can develop daily physical activities.

In this paper, we present the theory and numerical implementation for a 2-D thermal inhomogeneity through the dynamical probe method. The main idea of the dynamical probe method is to construct an indicator function associated with some probe such that when the probe touch the boundary of the inclusion the indicator function will blow up. From this property, we can get the shape of the inclusion. We will give the numerical reconstruction algorithm to identify the inclusion from the simulated Neumann-to-Dirichlet map.

The theory of generalized Besov-Morrey spaces and generalized Triebel-Lizorkin-Morrey spaces is developed. Generalized Morrey spaces, which Mizuhara and Nakai proposed, are equipped with a parameter and a function. The trace property is one of the main focuses of the present paper, which will clarify the role of the parameter of generalized Morrey spaces. The quarkonial decomposition is obtained as an application of the atomic decomposition. In the end, the relation between the function spaces dealt in the present paper and the foregoing researches is discussed.
