Objectives : The purpose of this research is to examine the effects of Sa-am acupuncture Simpojeongkyeok treatment on Hwa-byung. Methods : The study was performed through a patient-assessor blind, randomized, placebo-controlled trial in which the volunteers, data collector and analyst were unaware of individuals which were receiving the treatment. Fifty volunteers were divided into a trial and a control group, each of which consisted of 25 subjects. The trial group was treated with Sa-am acupuncture Simpojeongkyeok, while needle insertion at non-acupoints was given to the control group. The Likert scale for major symptoms of Hwa-byung was measured as the 1st evaluative instrument, and then a comparative analysis was conducted by comparing the results with those measured by of STAXI-K, STAI-K and BDI-K. Results : In the Likert scale comparison of major symptoms, total scores in both groups were decreased after treatment. However, a more significant decrease was found in those of trial group compared to those of the control group from a statistical perspective. The results measured by BDI scores also decreased significantly in the trial group after treatment. In comparison of STAXI and STAI scores, there were no significant differences found between the groups. Conclusions : The results suggest that Sa-am Acupuncture Simpojeongkyeok treatment is effective in the treatment of Hwa-byung.

In order to utilize unsorted ONP, which contains leaflets (printed coated papers), as a raw material to produce pulp mold, optimum conditions for repulping were investigated with the pilot Helico pulper at Centre Technique du Paper (CTP), France. Two major process factors were focused: repulping concentration and rotor speed. Repulping at a higher concentration showed more rapid defibering kinetics. Increasing the rotational speed of rotor at the optimum repulping concentration accelerated the defibering kinetics while it also led to higher fines generation and faster decrease in drainage property of the produced pulp. Hence, an alternative way was suggested: starting repulping at a conventional rotor speed and then accelerating the rotor speed for the last minute(s) of repulping.

The pilot scale ultrasonic deinking was carried out in order to confirm the commercialization possibility of ultrasonic deinking. White ledger was used as a raw material and the results were compared to the results obtained from the conventional deinking. The fraction of smaller ink particle was increased and the improved ink removal efficiency was also obtained by the ultrasonic treatment. The brightness and breaking length of ultrasonic deinked pulp were superior to those of the conventional deinked pulp. Most interesting findings in this study were that the significant improvement in effluent quality and the reduction of chemicals and energy cost were obtained by the ultrasonic deinking.

Composting of water hyacinth, mixed with cattle manure, rice husk and sawdust in four different proportions, was performed in a pilot scale rotary drum composter. The physico-chemical characteristics, i.e., temperature, moisture content, pH, electrical conductivity, total organic matter (OM), nitrogen dynamics and nutrients were evaluated during the 20 days composting process. The stabilities of the composts were also investigated with respirometric analysis, i.e., $CO_2$ evolution rates and oxygen uptake rate (OUR). Among all trials, trial 1 (6 water hyacinth, 3 cattle manure, 1 rice husk) indicated the best composting mix, as shown by the highest temperature profile and OM loss, and lowest $CO_2$ evolution rate and OUR.

This study aimed to pilot test a newly developed bilateral upper limb rehabilitation training program for improving the upper limb function of individuals with chronic stroke using a visual feedback method. The double-group pretest-posttest design pilot study included 10 individuals with chronic stroke (age >50 years). The intervention (four weekly meetings) consisted of five upper limb training protocols (wrist extension; forearm supination and pronation; elbow extension and shoulder flexion; weight-bearing shift; and shoulder, elbow, and wrist complex movements). Upper limb movement function recovery was assessed with the FuglMeyer Assessment of the Upper Extremity, the Wolf Motor Function Test, the Trunk Control Test, the modified Ashworth Scale, and the visual analog scale at baseline, immediately after, and four weeks after the intervention. The Fatigue Severity Scale was also employed. The Fugl-Meyer Assessment of the Upper Extremity and Wolf Motor Function Test showed significant improvement in upper limb motor function. The Trunk Control Test results increased slightly, and the modified Ashworth Scale decreased slightly, without statistical significance. The visual analog scale scores showed a significant decrease and the Fatigue Severity Scale scores were moderate or low. The bilateral upper limb training program using the visual feedback method could result in slight upper limb function improvements in individuals with chronic stroke.

Objectives : The aim of this study was to evaluate the effectiveness and safety of acupuncture for chronic fatigue syndrome and idiopathic chronic fatigue. Methods : A randomized, controlled pilot trial was conducted. Twenty-four participants were randomized into one of the two groups: an acupuncture group(n=12) and wait-list group(n=12). The treatment group received 12 sessions of acupuncture over 4 weeks. Eight points($GV_{20}$; bilateral GB20, $BL_{11}$, $BL_{13}$, $BL_{15}$, $BL_{18}$, $BL_{20}$, and $BL_{23}$) were selected for needling. The control group did not receive acupuncture treatment during study period and follow-up were done in the $5^{th}$ and $9^{th}$ weeks after randomization in both groups. The primary outcome was fatigue severity scale(FSS) and the secondary outcomes included a short form of stress response inventory(SRI-short form), beck depression inventory(BDI), and insomnia severity index(ISI). Safety was assessed at every visit. Results : There were statistically significant differences in the between group values of FSS at $5^{th}$ weeks after randomization(p=0.0002), SRI-short form, BDI, and ISI at $5^{th}$, $9^{th}$ weeks after randomization(p<0.01). There were no adverse events. Conclusions : The results suggest that acupuncture is associated with benefits on the short-term outcomes in chronic fatigue syndrome and idiopathic chronic fatigue.

In case of Korea, The Large-scale fire is consistently being such as 2015 Uijeongbu Fire, 2017 Jecheon Fire, 2018 Sejong Hospital Fire. Such a fire has a problem that the fire is spreading upper due to external flame spread. As a countermeasure the fire safety, the study about axial temperature prediction of external flame spread is consistently doing. But in korea, Vertical spandrel is specified as 40cm, and improvement is urgently needed. In this study, a repair material was selected to prevent the fire from spreading to a building where a flammable exterior material was installed and then pilot construction was carried out. Also, fire safety measures for buildings constructed with flammable exterior materials were examined.

This review was conducted to investigate clinical trial trend, clinical effect, and study methods of forest healing. Literature search was performed using the search engines of eight electronic databases from inception to march 2010 without language limitation. The search terms were "forest healing", "forest experience", "forest therapy", "forest treatment", "clinical trial", and "clinical study". Inclusion criteria were randomized controlled trials (RCTs) among all kinds of study searched about forest healing. Selection literature and data extraction was performed by authors(SH Sun and SG Lee) independently. Total three studies were selected finally. The methodological quality in all study was low because of poor reporting. Study indications were metal health, depression, self-esteem, and stress. The scale of studies was very small, which was the level of pilot study. There were no description for obtaining informed consent and being reviewed by Institutional Review Board (IRB), and could be any problems for statistical method in any studies. It is difficult to accept the fact that each studies had the significant effect for study indications in the results of studies. It is concluded that the evidence that health healing have a significant effect is insufficient. Further systematic and methodological study and well-designed clinical trial will be needed.

It is necessary to estimate hydrodynamic coefficients to design the auto-pilot system and motion simulator of submersible vehicle. In this paper, an algorithm was designed to estimate hydrodynamic coefficients of submersible vehicle. Using this algorithm, the hydrodynamic coefficients were estimated from measurements of full scale trial. The estimated hydrodynamic coefficients were used for the design of an auto-depth controller(ADC) of submersible vehicle, and the resulting ADC are proved to have a better performance than the previous one.

The autonomic regulation of heart rate (HR) is an indicator of the body's ability to adapt to an exercise stimulus. However, there are no reports on this topic in relation to Jeju horses used for racing. The aim of this study was to analyze the HR responses of Jeju horses during race trials and to investigate the correlation between HR and performance in these horses. HR data were collected from 17 healthy 2- to 7-year-old Jeju horses wearing HR monitors during race trials. Pearson correlation coefficients was used to determine the significance of the association between the race trial time and HR. A significant inverse correlation was observed between the race trial time (performance) and both the maximal HR (HRmax, r = -0.69, p < 0.01) and HR reserve (HRR) (HRmax - average HR during the warm-up period, r = -0.63, p < 0.01) and between the HRR and HRmax (r = 0.73, p < 0.01). Horses with a lower average HR during the warm-up period and higher heart rates during the trial achieved faster race trial times. This study reports the first HR measurements in Jeju horses during race trials, providing new insights into the HR response of this breed to exercise. The use of a noninvasive remote HR monitor system allowed assessment of exercise responses in the field, and the results suggest that both the HRR during warm-up period and HRmax may be useful performance indicators in Jeju horses.
