The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

The purpose of this study was to measure the mean peak mobilization forces to the cervical spine 3-5 with grade III and grade IV of posteroanterior (PA) mobilization. Asymptomatic 25 college subjects were participated in the trial and eligible physical therapists performed cervical mobilization. The mean peak mobilization force was measured during the PA mobilization with grade III and grade IV by attaching a flexible force transducer over the C3-C5 spinous process. Three cycles of PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. After applying the grade III mobilization to the C3-C5, 30 minutes later, the grade IV mobilization was applied to the same area again. There were no significant differences between C3, C4 and C5 during grade III as well as grade IV. Upon comparing the mean peak force of grade III with mean peak force of grade IV at the C3, C4 and C5 respectively, an insignificant difference was also observed. The mean peak mobilization force was 4.53±1.79 N at the C3, 5.10±1.91 N at the C4, and 5.17±2.63 N at the C5 during grade III force was applied. The mean peak mobilization force was 4.40±1.56 N at the C3, 5.53±2.01 N at the C4, and 5.38± 2.73 N at the C5 during grade IV force was applied. This study suggested that the mean peak force of the grade III and grade IV mobilization in the C3-C5 was similar each other, also there was no difference between mean peak force of grade III and grade IV on C3, C4 and C5.

Salt is generally used for food seasonings and preservations as a common ingredient. However, excess salt intake has generated health issues such as high blood pressure, osteoporosis, stroke, and heart diseases. Recently, desires and interests of low-salt cooking have been increased among people who want healthy diets. The aim of study was to compare the physicochemical characteristics of a fermented squid sauce added with vitamin C and commercial low-salt soy sauces. Thawed and crushed squids were fermented until the solid squid became liquid at 25°C with an addition of 5% (g/g) vitamin C. Then, fermented squid sauce was heated at 100°C for 30 min and filtered. All samples were measured in multiple aspects of amino acid nitrogen, salt, sugar and water content, pH, chromaticity and brown color, and sensory test. In the results, color values showed no significantly difference between all the samples (p>0.05). Water content value of the fermented squid sauce was the highest among samples. Brown color, salt contents and sugar contents of the fermented squid sauce were significantly different than other low salt soy sauces with an exception of the sauce made with functional salt. These results showed a similar tendency as those of sensory evaluation. As conclusion, the possibility of fermented squid sauce added with vitamin C showed a possibility as a candidate of low-salt soy sauce.

In this study, we investigated the change of physical properties associated with the temperature of vegetable mixed oil and fat in order to produce vegetable oil and fat suitable for plant meat production. The canola oil and coconut oil were mixed at various weight ratios, and the phase change temperatures by the ratio of two oils were measured using the differential scanning calorimetry (DSC). Storage modulus (G'), loss modulus (G") and viscosity were measured using a rheometer at 20-40°C and 0.4 Hz-100 Hz. Storage modulus (G') at constant frequency (10 Hz) was measured in a continuous section of 10-50°C. As the coconut oil content increased, the peak of the melting point moved to the lower side. The viscosity was higher in order of canola oil, mixed oil, and coconut oil, and the viscosity showed a tendency to decrease as the temperature increased. In the liquid state, it showed a tendency to increase after the value of storage modulus (G') and loss modulus (G") decreased from 0.634 Hz-1 Hz. The conversion time point of storage modulus (G') of continuous temperature change is consistent with the melting point temperature of DSC, as the passed start at 10°C, storage modulus (G') increased with an exception of canola oil. Using these results, we will pursue to produce a mixed plant oil applicable to the production of vegetable meat.

에너지 음료는 카페인을 주성분으로 타우린, 비타민 같은 다른 energy-enhancing 성분을 함유하고 있다. 미국과 유럽에서는 글루쿠로노락톤이 에너지 음료에 첨가될수 있으나, 국내에서 의약품으로는 허가되어 있다. 따라서 식품 첨가물로는 그 사용이 금지 되어 있어, 지속적으로 수입 및 유통 음료에서 시험검사를 하여 규제하고 있다. 현재 분석법으로 사용하는 LC-PDA 법은 복잡한 유도체화 과 정을 거치고, 음료 중에 당류들이 위양성 결과를 나타내 기도 한다. 이런 기존 방법의 단점을 개선하기 위해 HILICESI- MS/MS (hydrophilic interaction liquid chromatography coupled to electrospray ionization tandem mass spectrometry) 를 이용한 분석법을 개발하고, 선택성, 직선성, 검출한계, 정량한계, 정밀도, 정확성, 재현성에 대하여 분석법 유효성 검증을 수행했고, AOAC, EURACHEM 가이드라인에 부합되는 결과를 얻었다.

We determined the effects of different water temperatures (15, 20, and 25℃) and photoperiod cycles (24L:0D, 12L:12D, and 0L:24D) on the oxygen consumption of the offspring of a cultured Japanese strain (JJ), a selected Korean strain (KK), and intraspecific hybrid strains (JK and KJ) of red seabream, Pagrus major, under starvation conditions. The different fish strains, water temperatures, and photoperiod cycles had effects on the mean oxygen consumption of fish. Oxygen consumption increased with increasing water temperatures for all photoperiod treatments (p <0.001). Fish held in continuous darkness (0L:24D) used consistently less oxygen than fish exposed to continuous light (p <0.05). The oxygen consumption of fish exposed to the light phase in a 12L:12D photoperiod was higher than that of fish in the dark phase of the 12L:12D cycle, and differences were significant in three of the strains: JJ (15℃), KK (15 and 20℃), and KJ (25℃). The oxygen consumption of the inbred (JJ and KK) and intraspecific hybrid (JK and KJ) strains varied with differing water temperatures and photoperiod cycles. The JK strain displayed significantly higher oxygen consumption than the other strains under all experimental conditions except 15℃ with a 0L:24D photoperiod. The JK and KJ strains usually showed the highest and lowest oxygen consumption values, respectively, whereas the inbred strains exhibited intermediate values. Oxygen consumption in the JJ and JK strains was usually higher than that of the KK and KJ strains. We propose that differences in the thermal sensitivity and photosensitization properties of the strains contribute to differences in their ability to adapt to changes in water temperature and photoperiod, thus resulting in differences in the amplitude of their metabolic rates.

This study was conducted to evaluate effects of supplementation of Bifidobacterium ruminantium on in vitro ruminal fermentation and methane production. Ruminal fermentation characteristics of Timothy hay (C1), whole barley (C2), Timothy hay + B. ruminantium (T1) and whole barley + B. ruminantium (T2) were evaluated at 0, 3, 6, 9, 12, 24 and 48 h incubation at 39℃. The amount of B. ruminantium culture added into T1 and T2 was 0.3 ml. The pH values ranged from 5.99 to 6.83 in all the treatments. Concentration of NH3-N of C2 and T2 was higher than C1 and T1 at 48 h (p<0.05). The total gas production of C2 and T2 was higher than C1 and T1 at 9 h (p<0.05). The total methane production of treatments with B. ruminantium was not significantly different at 24 and 48 h (p<0.05). Concentration of lactic acid was significantly different between both substrates (p<0.05). Therefore, B. ruminantium supplementation was determined to be insignificant in the in vitro ruminal fermentation and methane production, while a further study was required to investigate relation to lactic acid production with different forage sources.

The purpose of this study is to provide fundamental clinical data for the treatment plan and rehabilitation of patients with cervical hypolordosis by comparing the cervical headache and muscle activity after cervical stretching exercise and cervical traction, which are generally applied to patients with cervical hypolordosis. The research subjects included 20 patients without gender division who were diagnosed with cervical hypolordosis. After applying cervical stretching exercise and cervical traction for six weeks, cervical headache and the activity of the muscles around the cervical vertebra(upper trapezius muscle, sternocleidomastoid muscle, splenius capitis muscle, and anterior temporal muscle) were investigated and the following results were obtained. In a comparison of the within group intervention effects of the two groups, cervical pain statistically significantly decreased in the cervical stretching exercise group. According to the results of analyzing the change of muscle tension in the upper trapezius muscle, both the cervical traction group and showed a statistically significant within group difference in the left and right side. According to the results of analyzing the change in the muscle tension of the splenius capitis muscle, both groups showed a statistically significant within group difference in the left and right side. In a betweengroup comparison, a statistically significant difference in the right side was observed. These results confirm that cervical vertebra traction and cervical stretching exercise decrease the cervical headache and muscle activity of the upper trapezius muscle and the splenius capitis muscle among patients with cervical hypolordosis.

Cockroaches are insects of the order Blattodea, sometimes also called Blattaria, of which about 30 species out of 4,600 total are associated with human habitats. About four species are well known as pests. Among the best-known pest species are the American cockroach, Periplaneta americana, which is about 30 mm long; the German cockroach, Blattella germanica, about 15 mm long. We researched growing condition of in-vitro(temperature and humidity) for P. americana and B. germanica. The cockroach is divided in three sections; the body is flattened and broadly oval, with a shield-like pronotum covering its head. A pronotum is a plate-like structure that covers all or part of the dorsal surface of the thorax of certain insects. They also have chewing mouth parts, long, segmented antennae, and leathery fore wings with delicate hind wings. The third section of the cockroach is the abdomen. We measured size of head, abdomen, and body length during differential stages. Also, we checked number of egg, size of egg, hatching rates, period of former laying eggs, and laying periods etc.

Vitellogenins (Vgs) are precursors of the major egg storage protein, vitellin (Vn), in many oviparous animals. Insects Vgs are large molecules (200-kD) synthesized in the fat body in a process that involves substantial structural modifications (e.g., glycosylation, lipidation, phosphorylation, and proteolytic cleavage, etc.) of the nascent protein prior to its secretion and transport to the ovaries. However, the extent to which Vgs are processed in the fat body varies greatly among different insect groups. We were cloned Vgs partial genes PaVgs and BgVgs from Periplaneta americana and Blattella germanica. Real-time quantitative PCR shows that PaVgs and BgVgs were differential-regulated with aging. In insects, glutathione S-transferases (GSTs) are enzymes involved in detoxification of insecticides. We were cloned GST partial genes PaGST and BgGST from Periplaneta americana and Blattella germanica. Real-time quantitative PCR shows that PaGST and BgGST were up-regulated with aging, and the mRNA level of PaGST and BgGST was higher in 4℃ and 37℃ than room temperature. The expression level of PaGST and BgGST exposure to temperature stress suggests that PaGST and BgGST are up-regulated after exposure low and hige temperature treatments.

The purpose of this study is to observe how balance exercise on an unstable platform and on a stable platform affects balance ability. The subjects were 35 adults in their 20s and were randomly assigned to a stable platform group and an unstable platform group. They performed balance exercise three times per week for six weeks. Balance exercise introduced by previous research was modified and complemented for use in this study. Balance ability of the subjects was measured through center of pressure(COP) area, medial-lateral displacement, and anterior-posterior displacement using a portable balance platform BT4. There was significant difference in the COP area between the unstable platform exercise group and the stable platform exercise group. In comparison in differences between the unstable platform exercise group and the stable platform exercise group after the exercise, there was significant difference in anteriorposterior movement. Therefore, exercise on an unstable platform is more effective than exercise on a stable platform in strengthening balance ability.

Jeon-Nam province has the largest number of managed honey bee(Apis cerana) colonies before 2009 years ago, which produce the highest quantity of honey in the Korea; however, almost colony were collapsed by Sacbrood Virus(SBV) in jeon-nam apiaries. We thus conducted a molecular survey of honey bee RNA viruses, Nosema microsporidia, Foul broods and fungal disease(Chalk brood and Stone brood) associated with environmental conditions in apiaries and differential A. cerana hives in Joun-nam province. We found the presence of black queen cell virus (BQCV), Israel Acute Paralysis Virus and Nosema apis. Sacbrood virus(SBV) was detected in the tested samples. Our results demonstrate that honey bee RNA viruses and N. apis are present in joen-nam province apiaries, and some might be related environment conditions(temperature and moisture).

The purpose of this study was to analyze lower limb muscle activity and 3D motion analysis according to change foot arch height during walking. We selected 9 young and healthy people who have been normal foot. And we selected 7 young and healthy people who have been flatfoot. So, people were divided into 2 groups and walked platform during 2 minutes twice for checked by 3D motion analysis. These data were characterized by EMG measurements of three muscles( tibialis anterior, medial and lateral gastrocnemius) while they were walking. The collected data were analyzed by Independent t test using the SPSS statistics program(Ver 12.0). In foot arch change, there were no significant difference in three muscles 3D motion analysis also found that there were no significant difference in joint angles. In this study was to analyze lower limb muscle activity and 3D motion analysis according to change foot arch, but there were no significant difference in 6 muscles neither joint angles.

This research was attempted to seek for a positive approach within the framework of physical therapy instead of the drug treatment in the past, with regard to the ischemic brain injury in the early stage. Accordingly, the aim of this research is to observe the change of HSP27 and HSP70, the genes that are expressed in the early stage of brain injury and to investigate the effects of needle electrode electrical stimulation(NEES), upon applying NEES after ischemia. The experimental method is to give rise to global ischemia and apply NEES to 27 SD-Pat rats with the particulars of being eight-week-old, male, around 300g, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 NEES group(n=9), L14 NEES group(n=9), no applied NEES global ischemia(GI) group(n=9), and then observe their changes of HSP27 and HSP70 at the time lapse of 6, 9 hr and 12 hr after ischemia, using immunohistochemistry methods. Upon observing through the immunohistochemistry method, it was noticed that there was a significant difference between the GV20 NEES group and the L14 NEES group as for HSP27 and there were significant differences among all groups as for HSP70(p<.05). Accordingly, it is supposed that the application of NEES after the outbreak of cerebral ischemia delay the apoptosis in the early ischemic part of forebrain or protect neurons against apoptosis.

This study was to examine on the respiratory variables, heart rate and muscle activity between the static recovery and dynamic recovery after progressive resistance exercise to maximal point. Subjects were 15 students enrolled in N University. All were tested two times (static recovery and dynamic recovery) and were requested to perform a walking on a treadmill after progressive resistance exercise to maximal point. Electromyography(EMG) was used to monitor the muscle activity(TA: Tibialis Anterior, MG: Medial Gastrocnemius) during gait. CPEX-1 was used to measure the respiratory variables and heart rate. The dynamic recovery group was shown the significant lower heart rate than that of static recovery group at during gait. Respiratory rate showed statistically a significant difference. Electromyography(RMS, root mean square) showed a non-significant difference. But the dynamic recovery group of muscle activity was found highly in TA and MG. This study indicated that the dynamic recovery method evidenced more faster than the static recovery method. And this type of dynamic rest by walking can be a help of recovery after exercise.

It has been reported that light-emitting diodes(LED) can be used in the treatment of oral diseases. Although bio-stimulatory effects of LED irradiation such as promotes stimulation of wound healing have been well known, there are few reports about molecular mechanism associated with cell cycle by LED irradiation. The purpose of present study was to examine the molecular event in cell cycle of LED irradiation on primary human gingival fibroblast(hGF) in vitro. The source of light for irradiation was a continuous-wave LED emitting at a wavelength of 635nm, and manufactured that energy density was 5mW/cm2 on sample surface. The hGF were irradiated for 1 hour at 37℃ in 5% CO2 humidified chamber. Experimental samples were acquired at 0 (right after irradiation), 8 and 24 hour after irradiation. To investigate the molecular mechanisms associated with cell cycle, growth phase was determined by flow cytometry and mRNA expression of cyclin A, cyclin B, cyclin D1, cyclin E, cdc2, PCNA, p18, p27, p21, and p53 were determined by real time RT-PCR. Flow cytometric analysis demonstrated the percentage of cells in the G1 and S phase were decreased, but the G2 phase increased, which showed cells irradiated by LED were transitioned from S to G2 phase. For mRNA expression, cyclin B, cdc2, PCNA and p53 were increased at 0 hour after irradiation, and most of cell cycle molecules were increased at 8 hour after irradiation. At 24 hour after irradiation, cyclin A, cyclin E, PCNA and p18 were increased. Taken together, LED irradiation induced proliferation of hGF cells through transition from S to G2 phase.
