Edible insects are an interesting alternative global food resource. The purpose of this study was to investigate whether ingestion of silkworm (Bombyx mori) pupae powder with and without resistance exercise training (isometric contraction training) increased muscle mass in ICR mice. To achieve this, 28 ICR mice were grouped into control (CON), resistance exercise training (EX), silkworm pupae powder ingested control (SP), and silkworm powder ingestion with resistance exercise training (SPEX) groups. The change in body weight ratio was significantly decreased in the EX and SPEX groups compared to the CON and SP groups. Total blood protein levels were the highest in SPEX mice compared to those in other groups. The albumin concentration increased only in the EX group. Blood GOT and GPT levels were not significantly affected. Changes in Akt and Gsk-$3{\beta}$ protein expression were not significant but there was a tendency for Akt to increase and for Gsk-$3{\beta}$ to increase following the ingestion of the powder. The size of the gastrocnemius muscle increased significantly in response to resistance exercise training only. Furthermore, the ingestion of silkworm pupae powder tended to increase muscle mass without significance. These results suggested that the ingestion of silkworm pupae powder with resistance exercise training might enhance muscle mass without hepatotoxicity. However, future study may be needed to obtained detailed results and practical suggestions.

The purpose of this study was to investigate effect of low intensity resistance exercise and aerobic exercise on serum lipid level in chronic stroke patients. A total of 37 chronic stroke patients were enrolled in this study. The participants were allocated randomly to 2 groups: the low intensity resistance exercise group(n=19) and aerobic exercise group(n=18). Low intensity resistance exercise group took exercise with low intensity resistance for 50minutes, 5 times per week over a 8 week period. Aerobic exercise group received only aerobic exercise. We measured serum lipid level to compare of effectiveness both exercises. Paired t test was executed to determine differences between pre and post exercise. For all analyses, a significant level set at p<.05. The low intensity resistance exercise group showed significant increase in TG, TC HDL-C and LDL-C(p<.05). The aerobic exercise group had significantly higher TC and LDL-C (p<.05). Theses results suggest that low intensity resistance exercise and aerobic exercise are feasible for stroke patients by improving motivation and interest. Further studies is necessary to clinical implication classified by onset time and disability level.

This study was conducted to investigate the effects of whole body vibration stimulation training combined with respiratory resistance on respiratory and balance function in stroke patients. 17 patients with chronic stroke were randomly assigned to the experimental group (n = 8) and the general vibration exercise program (n = 9). The intervention was conducted three times a week for 30 minutes once a week for 4 weeks. The respiratory function and balance ability were evaluated before and after the intervention to evaluate the degree of functional improvement. As a result, there was a significant difference (p<.05) between the respiratory function and the balance ability in the experimental group, and a significant difference(p<.05) in the respiratory function between the experimental group and the control group. The balance ability was not significantly different among the experimental groups. Through the results of this study, whole body vibration stimulation training combined with respiratory resistance may be useful as a program for improving respiratory function and balance ability of stroke patients.

In this study, the piezoresistive properties of cementitious composites enhanced with carbon nanotubes for improved electrical conductivity were analyzed using a deep learning-based transformer algorithm. Experimental execution was performed in parallel for acquisition of training data. Previous studies on mixture design, specimen fabrication, chemical composition analysis, and piezoresistive performance testing are also reviewed in this paper. Notably, specimens in which fly ash substituted 50% of the binder material were fabricated and evaluated in this study, in addition to carbon nanotube-infused specimens, thereby exploring the potential enhancement of piezoresistive characteristics in conductive cementitious materials. The experimental results showed more stable piezoresistive responses in specimens with fly-ash substituted binder. The transformer model was trained using 80% of the gathered data, with the remaining 20% employed for validation. The analytical outcomes were generally consistent with empirical measurements, yielding an average absolute error and root mean square error between 0.069 to 0.074 and 0.124 to 0.132, respectively.

본 연구는 기업이 기술제품을 도입한 후에 내부에 확산시키려고 하는 실행단계에서 직면하는 혁신저항에 영향을 미치는 요인과 혁신저항을 줄이고 확산을 증진시키는 확산촉진활동을 설명하여 2B 마케팅 상황에서 기술제품의 조직내 혁신저항-확산모델을 도출하였다. 기업에서 기술제품을 조직내에 확산시킬 때는 구성원들의 혁신저항을 접하게 된다. 소비자 행동에서는 혁신저항에 영향을 주는 변수로 개인변수와 제품변수를 제시하고 있지만 2B 마케팅에서는 조직구조변수와 구매센터변수가 추가적으로 영향을 주게 된다. 중앙집권화, 공식화정도가 높은 기업에서는 구성원들이 혁신저항을 가지면서도 사용할 수 있다. 이러한 경우에는 판매기업과 구매기업의 관계가 단기적인 관계로만 그칠 수 있다. 또한 구매센터 참여정도가 적고 구매센터가 집중화되어 있으면 혁신저항이 커지고 단기적인 관계만 형성될 가능성이 커진다. 그리고 제품의 지각된 위험, 적합성에 따라 혁신저항의 정도가 달라질 것이다. 그리고 사용자 개인의 지각된 자기능력, 현 제품의 만족도 등이 의미있는 조절 변수 역할을 할 것이다. 그러므로 장기적인 관계로 이어지기 위해서는 혁신저항을 줄이는 교육훈련, 제품개선, 부서간 조정, 개인적 동기 부여와 같은 확산촉진활동이 있어야 한다. 따라서 본 연구를 통해 판매기업과 경영자들은 기술제품에 대한 혁신저항을 극복하고 제품을 확산시킬 수 있는 학문적, 관리적 시사점을 얻을 수 있을 것이다.

The purpose of the present study was to investigate the effect of climbing resistance training on GLUT-4 protein and LDH isozyme activities of the soleus and gastrocnemius muscles in rats. Each experimental group was randomly divided into a control group (n=6) and a resistance exercise (n=6) group. Sprague-Dawley rats were made to climb a 180 cm tower for 12 wk. Weight changes in the resistance exercise group were significantly higher than in the control group (p<0.05). GLUT-4 protein expression of the soleus and gastrocnemius muscles was significantly higher (p<0.05) in the resistance exercise group than in the control group. There was no difference in soleus tissue LDHA4 isozyme activity between the groups. In the case of other LDH isozyme, when compared with the control group, the resistance exercise group showed a significantly higher activity (p<0.05). LDHA4 activity of gastrocnemius muscle tissue was not different between the groups. However, the activity of the resistance exercise group of all the other LDH isozymes was significantly higher than that of the control group (p<0.05). In summary, based on the results of this study, over 12 weeks of resistance training, the total body weight of the rats was reduced and the GLUT-4 activity in the gastrocnemius and soleus muscles was increased. In addition, except for LDH A4 all of the other LDH isozymes activities were increased. These results suggest that climbing resistance training affects the balance of body composition, increases LDH B-type isoenzymes and glucose metabolism capacity, and improves mitochondrial function.

As information systems are implemented in business organizations, users and other stakeholders are known to resist changes incurred by information systems being implemented. For successful implementation, it is critical to manage changes overcoming resistance. Through literature review and expert panel, this study derives four underlying dimensions of resistance (anxiety, suspicion, imposition and self-centeredness) and five categories of change management activities (vision, leadership, communications, education and training, and organizational culture). A Survey was designed to measure the relationship between these dimensions and activities, and administered among information systems consultants. It is found that activities related to vision and leadership is underpinning other change management activities. Anxiety and imposition can be mitigated by education and training while suspicion is to be overcome by communications and self-centeredness by activities related to cultural changes. Implications are discussed and further researches are suggested.

This study was performed to determine the effect of low-intensity resistance training with blood flow restriction (BFR) on muscle volume and strength in elderly women. Sixteen elderly women (70.9±4.6 years) were divided into low (30% 1RM) and high (75% 1RM) intense resistance training groups. Tourniquet cuff (Zimmer, Germany) for BFR was applied only to the right leg during the training period. All subjects performed unilateral leg press, leg extension and leg curl (3 sets×12 repetitions) for 10 weeks (2d/wk). Blood pressure was increased from 110 to 240 mmHg during the training period at the most proximal region of exercised leg. Muscle volume and cross-sectional area (CSA) were measured by MRI and body composition was monitored by dual-energy X-ray absorptiometry (DEXA) and isokinetic muscular strength were analyzed in both legs. The quadriceps CSA (15.2%, p<.001) and muscle volume (13.8%, p<.001) were increased in high-intense trained leg with BFR and the increased rate was highest among groups. The quadriceps CSA (9.8%, p<.001) and muscle volume (6.9%, p<.001) were increased in low-intensity training group with BFR and their increased rates were higher than control groups. The strength by exercise training was significantly improved in all groups and tended to be higher in BFR groups. These results demonstrate low-intensity resistance training with blood flow restriction could be an effective way to improve muscle volume and strength in elderly women.
