  • Purpose : N.A.P.(Neuromuscular Skeletal Plasticity) an integrative neuro-orthopedic concept to facilitate motor strategies in daily life. The primary thesis is, that treatment of body functions and structural impairments should be integrated within goal-oriented activities. The purpose of this article is to demonstrate that the functional activity itself, determines the structure. Material and Methods : A case report of a dentist with brachial plexus lesion after a motor vehicle accident is presented. The necessity for training body functions within relevant tasks is undermined by references which emphasize the importance of training realistic activities to enhance long-term changes in neural representation. Results : The treatment methods presented in this case show significant effects for the patient's ability to participate in his profession within less than a year's time after his motor vehicle accident. Conclusions : Current evidence supports the treatment methods of this concept. The inability to flex his elbow and supinate his forearm placed a considerable doubt to his ability to ever be able to participate in his profession again. Structural reorganization is possible and depends on functional demands, which need to be trained task-specifically. Single case reports may serve as the basis for further randomized controlled studies to support the efficacy of the treatment methods within the N.A.P. concept.

  • Structural Health Monitoring System (SHMS) works as an efficient platform for monitoring the health status and performance deterioration of engineering structures during long-term service periods. The objective of its installation is to provide reasonable suggestions for structural maintenance and management, and therefore ensure the structural safety based on the information extracted from the real-time measured data. In this paper, the SHMS implemented on a world-famous kilometer-level cable-stayed bridge, named as Sutong Cable-stayed Bridge (SCB), is introduced in detail. The composition and core functions of the SHMS on SCB are elaborately presented. The system consists of four main subsystems including sensory subsystem, data acquisition and transmission subsystem, data management and control subsystem and structural health evaluation subsystem. All of the four parts are decomposed to separately describe their own constitutions and connected to illustrate the systematic functions. Accordingly, the main techniques and strategies adopted in the SHMS establishment are presented and some extension researches based on structural health monitoring are discussed. The introduction of the SHMS on SCB is expected to provide references for the establishment of SHMSs on long-span bridges with similar features as well as the implementation of potential researches based on structural health monitoring.

  • A-type $K^+$ ($I_A$) channels are transiently activated in the suprathreshold membrane potential and then rapidly inactivated. These channels play roles to control the neuronal excitability in pyramidal neurons in hippocampi. We here electrophysiologically tested if regulatory functions of $I_A$ channels might be targeted by acute activation of glutamatergic synaptic transmission in cultured hippocampal neurons(DIV 6~8). The application of high KCl in recording solutions(10 mM, 2 min) to increase presynaptic glutamate release, significantly reduced the peak of somatic $I_A$ without changes of gating kinetics. This indicates that neuronal excitation induced by the enhancement of synaptic transmission may process with distinctive signaling cascades to affect voltage-dependent ion channels in hippocampal neurons. Therefore, it is possible that short-lasting enhancement of synaptic transmission is functionally restricted in local synapses without effects on intracellular signaling cascades affecting a whole neuron, efficiently and rapidly enhancing synaptic functions in hippocampal network.

  • Amputation changes the lives of patients and their families. Consequently, the patient must adapt to altered body function and image. During this adaptation process, psychological problems, such as depression, anxiety, and posttraumatic stress disorder, can occur. The psychological difficulties of patients with amputation are often accepted as normal responses that are often poorly recognized by patients, family members, and their primary physicians. Psychological problems can interfere with rehabilitation and cause additional psychosocial problems. Therefore, their early detection and treatment are important. A multidisciplinary team approach, including mental health professionals, is ideal for comprehensive and biopsychosocial management. Mental health professionals could help patients set realistic goals and use adaptive coping styles. Psychiatric approaches should consider the physical, cognitive, psychological, social, and spiritual functions and social support systems before and after amputation. The abilities and limitations of physical, cognitive, psychological, and social functions should also be considered. To improve the patient's adaptation, psychological interventions such as short-term psychotherapy, cognitive behavioral therapy, mindfulness meditation, biofeedback, and group psychotherapy can be helpful.

  • Kidney disease is a major global health issue. Hemodialysis and kidney transplantation have been used in the clinic to treat renal failure. However, the dialysis is not an effective long-term option, as it is unable to replace complete renal functions. Kidney transplantation is the only permanent treatment for end-stage renal disease (ESRD), but a shortage of implantable kidney tissues limits the therapeutic availability. As such, there is a dire need to come up with a solution that provides renal functions as an alternative to the current standards. Recent advances in cell-based therapy have offered new therapeutic options for the treatment of damaged kidney tissues. Particularly, cell secretome therapy utilizing bioactive compounds released from therapeutic cells holds significant beneficial effects on the kidneys. This review will describe the reno-therapeutic effects of secretome components derived from various types of cells and discuss the development of efficient delivery methods to improve the therapeutic outcomes.

  • The development and introduction of a Maritime Autonomous Surface Ship (MASS) are some of the most important changes leading to the fourth industrial era in the maritime area. The term 'MASS' refers to a ship operating independently, without human intervention, to reduce maritime accidents caused by human errors. Recent UK findings MASS also noted that particularly the dynamic positioning system will be considered to apply as newly function to a MASS. The DP system, a ship system developed decades ago and used for specific purposes like offshore operations, provides various functions to facilitate the accurate movements of the vessel, and operators can make decisions within the DP system, in addition to the ordinary ship system. In this paper, it would like to present the connection and application method with the main technical elements of the DP system in connection with the main technology of the DP system to achieve the safe operation of a MASS. In particular, among various position reference systems, the capability plot function of DP system, and the "follow target" mode in the operation mode are attractive functions that can contribute to the safe operation of autonomous ships.

  • It is generally believed that Seonjeong-jeon and Heejeong-dang respectively served as Pyeonjeon of Chang-deok Palace in the earlier and the later period of Joseon dynasty. However, such belief is based on the concept of Pyeonjeon that emerged after the time of King Soonjo's reign(1800~1834). The concept and functions of Pyeonjeon varied among times ranging from Koryo to late Joseon dynasty. In the earlier Koryo dynasty, the word Pyeonjeon signified both "Pyeonjeon in relation to Jeong-jeon" or "Pyeonjeon as a casual office for the king". The ambiguity of the word was resolved when Bopyung-cheong and Jogye-cheong were established in the earlier Joseon dynasty. These buildings in Chang-deok Palace (and only Bopyung-cheong in Gyeong-bok Palace) held rituals related to events in Jeong-jeon, as well as their exclusive political rituals. Thus, the meaning of the term "Pyeon-jeon" became restricted to its second meaning, namely a casual building for the king's everyday office work and small banquets. However, the ambiguity reemerged from around the time of King Seong-jong's reign(1469~1494). In this period, Pyeonjeon as in relation to Jeong-jeon was often referred to as "Jeong-jeon", or "Beop-jeon" from the mid-16th century. In the 19th century, Pyeonjeon as king's casual office took over the characteristics and functions of Beop-jeon. Thus, the popular notion of "Pyeon-jeon" was newly established and passed onto nowadays.

  • In an attempt to observe the to long-term training effects, the exercise of rope-skipping was regularly loaded to nine soldiers for nine weeks. And some physical characteristics, cardiopulinonary functions. some blood constituents were measured before, during and after the load of test exercise. treadmill running, and were compared with the pre-trained values. The results obtained were as follows: 1) Body weight, body surface area, skinfold thickness and total body fat decreased sifnificantly after the training. 2) The post-trained values of MVV and $FEF_{25%}$, increased significantly. 3) By the training, heart rates decreased very significantly in the resting, exercising and recovery periods. 4) After the training, the systolic blood pressures of the resting and recovery periods decreased meaningfully, while diastolic blood pressures increased significantly through the recovery stages. 5) In spite of the training, the respiration rates never change in both the resting and the recovery periods. 6) After the training, total cholesterol concentration of the venous blood decreased significantly in the resting the early recovery phases while the blood levels of glucose and HDL-cholesterol decreased very slightly. 7) Blood lactate concentration decreased through the recovery periods and the value of the recovery 20 and 60 minutes decreased obviously, in comparison with the pre-trained values. The above results suggest that the 9 week-training of the rope-skipping brings about the decrease of the body fat contents, the enhancement of cardiopulmonary functions and some changes in the blood constituents.

  • This study aims to analyze the effect of urban ecosystem restoration projects by evaluating the short-term restoration performance of the project sites, from both qualitative and quantitative evaluations. In this study, for the qualitative evaluation, we derived the evaluation frame from previous studies and literature. For the quantitative evaluation, the changes in ecological connectivity after the restoration project were described using landscape permeability and network analysis. In addition, changes in habitat quality after the restoration project were evaluated by using InVEST Habitat Quality Model. These evaluations were applied to the three natural madang (ecological restoration) projects and two ecosystem conservation cooperation projects. As a result, three categories, 10 indicators, and 13 sub-indicators were derived from literature as the evaluation frame for this study. In the case of quantitative evaluation of restoration performance, habitat quality increased by 45% and ecological connectivity by 37% in natural-madang, and habitat quality by about 12% and ecological connectivity by about 19% in ecosystem conservation cooperation projects. This implies that the ecological restoration project can increase the ecological connectivity and the habitat quality of degraded sites even in a short period of time by improving the land-cover and land use. The results by applying the evaluation frame indicated that ecological and environmental factors and the ecological functions were improved by the restoration works, even though the magnitude of performances were diverse depending on the specific evaluation items, project type, and site characteristics. This study clarified that the success of ecological restoration project should be assessed by both of the short-term and long-term goals, which can be achieved by the maintenance and sustainable management, respectively.

  • Douglas-fir (Pseudotsuga menziesd Mirb. Franco) is highly regarded as a commercial timber species throughout the world in part due to its fast growth relative to many other species. In this study, basal area per hectare equation for Douglas-fir plantations in Southland of New Zealand has been developed based on medium measurement cycles of permanent sample plots data set. The function was developed using the algebraic difference equation method, and various sigmoid-shaped projection equations were used. Parameter estimation was obtained by non-linear routine of the SAS. As a result, of the functions tested a variant of the Schumacher polymorphic function including site index and thinning term as predictor variables showed the higher precision of the fitting. The results indicate that site index is positively correlated with basal area growth. And the thinning term was found to be useful to increase precision of the model.
