When feeling the pulse, healthy man' pulse is the criterion for diagnosis whether you are a sick person. Healthy man is defined as one who is harmonious and not sick in sympathy with natural order. Among the factors for being Healthy man, breathing and pulsation, Chon-gu(寸口) and Inyeong(人迎) are most closely connected with the representative methods of feeling the pulse which are used currently. According to "Hwangjenaegyeong(黃帝內經)" on breathing and pulsation, the pulse beats twice per a breathing-in and a breathing-out each. And for a specific breathing, it beats 5 times including the remnant with a big breath. That the pulse beats twice means that it beats not only twice, but also regularly and repeatedly. The remnant is related to the meaning on a leap month, 5-time beating during a breath is connected with the contents of Osipyeong(五十營). A human is not always in stable and sticks to balance continuously with changes under the circumstances. So when it comes to a criterion how to measure the pulsation frequency, breathing is much more reasonable than pulsation and breathing calculated for a minute. According to "Hwangjenaegyeong(黃帝內經)", Healthy man is the person of whose Chon-gu and Inyeong are in order and much the same in response to each other. Although there is a minor difference in the meaning of term between Chon-gu and Gigu(氣口), Maekgu(脈口) in originally, it is used as almost same meaning when Chon-gu is used in opposition to Inyeong. Afterwards, depending on medical men, around neck or Chon-gu of the left hand are measured for Inyeong. However, Inyeong described in "Naegyeong(內經)" is Jokyangmyeong(足陽明) and it means the Hyeol(穴) around neck where the pulse beats, it looks like about the carotid area. Chon-gu is fall under Eum(陰) and Inyeong(人迎) is fall under Yang(陽). Therefore Chon-gu is continuous with eumgyeong(陰經) and Inyeong is continuous with yanggyeong(陽經). In addition, the pulse and the four seasons meet each other and Inyeong is a little stronger in spring summer and Chongu is a little stronger in fall winter.

Since ${\ll}$Hwangjenaegyeong(黃帝內經)${\gg}$ and ${\ll}$Nangyeong(難經)${\gg}$, there has been various methods in pulse diagnosis. The Chon-gu(寸口)/Inyeong(人迎) Pulse Comparison Diagnosis which is dealt with in many chapters of the ${\ll}$Hwangjenaegyeong${\gg}$, has not been as widely applied as the Chon-gu Pulse Diagnosis due to several limitations. In this paper, we will review these limitations and suggest an alternative method. In the Chon-gu/Inyeong Pulse Comparison Diagnosis, we compare the Chon-gu Pulse and the Inyeong Pulse to see which is larger than the other by times, and diagnose illness of the 12 Meridian Pulse. It is fairly clear which is larger than the other, but to determine by how much accurately is quite difficult to say. However if we combine the Five Viscera Pulse in application, it becomes far more easier to determine which viscera and bowel is ill. First, study the pulse of the Chon-gu and In-yeong, then determine the Viscera Pulse. Next, determine the larger pulse between the Chon-gu and In-yeong pulse.

Tinnitus is usually due to insufficiency of Kidney-essence, asthenia of the Spleen and Stomach, diseases caused by exogenous pathogenic factor, Liver fire(肝火) by severe stress, Phlegm -fire(痰火) by surfeit of high caloric food and alcoholic liquor. I observed and treated four patients who had been diagnosed with tinnitus of Liver-fire(肝火) and Phlegm-fire(痰火). After I checked the Inyeong(人迎) and the chon spot(寸口), all of their Inyeong were stronger than chon spot. Unbalance of the Inyeong(人迎) and the chon spot(寸口), and symptoms of tinnitus were removed by Acupuncture therapy of three Yang meridians of the hand(手三陽) and three Yang meridians of the foot(足三陽).

The common octopus, which has a high growth rate and high market price, is a prime candidate for commercial marine aquaculture operations. We evaluated the effectiveness of two types of shelters (pipe and tire types) for juvenile common octopus growing out in flow-through seawater tanks. Growth rates were evaluated in two experiments. The first experiment (Experiment 1) ran for 72 days, and the second (Experiment 2; replicated) ran for 46 days. Each trial included 40 octopuses fed a diet of frozen sardine (Sardinops melanostictus) and swimming crab (Portunustri tuberculatus) at 3-8% of body weight once every 3 days. In the two experiments, the respective specific growth rates were 0.3 and 0.04%/day in pipe-type shelters and 0.00 and 0.88%/day in tire-type shelters, while the respective percentage survivals were 80 and 80% in pipe-type shelters and 70 and 90% in tire-type shelters. Shelter type had little influence on the growth rate (P < 0.05).

The objective of this study is to develop education programs for cultivating smart aquaculture experts through a education demand survey of industries, high school students, university (graduate) students and field workers. The industry demand analysis was conducted as an in-depth interview on representives from seven companies. Education demand surveys were conducted on 96 students and field workers in the Jeonnam region. Results on the demand survey were analyzed using frequency analysis and cross-analysis. The company representatives responded that they want to participated in internship and retraining programs to proactively secure manpowers with convergence capabilities about smart aquaculture. Seven companies preferred manpowers with basic competencies on ICT (Information and Communications Technologies) or aquaculture. The most respondents in the demand survey want to participate in the education program for experience on advanced technology, self-development and enhancement of work capability. On the other hand, some respondents said that the education is time-consuming and that the education program does not fit their level. Thus, the education program should be developed in a way to minimize the spatial and temporal limitations of education targets and to improve understanding of non-majors by reflecting the demands of human resources in the industrial field.

The objectives of this study were to develop the optimal structures of recirculating aquaculture tank for improving the removal efficiency of solid materials and maintaining water quality conditions. Flow analysis was performed using the CFD (computational fluid dynamics) method to understand the hydrodynamic characteristics of the circular tank according to the angle of inclination in the tank bottom (0°, 1.5° and 3°), circulating water inflow method (underwater, horizontal nozzle, vertical nozzle and combination nozzle) and the number of inlets. As the angle in tank bottom increased, the vortex inside the tank decreased, resulting in a constant flow. In the case of the vertical nozzle type, the eddy flow in the tank was greatly improved. The vertical nozzle type showed excellent flow such as constant flow velocity distribution and uniform streamline. The combination nozzle type also showed an internal spiral flow, but the vortex reduction effect was less than the vertical nozzle type. As the number of inlets in the tank increased, problems such as speed reduction were compensated, resulting in uniform fluid flow.

The sea cucumber, Apostichopus japonicus, is becoming an important aquaculture species in China, Japan and Korea. The purpose of this study is to evaluate the biological performance of a tubular type of subsurface cage for sea cucumber grow-out by in-situ tests. The cage structure was constructed of PP (polypropylene) frames and PP tubes (${\phi}130mm{\times}24pieces$). A set of tests were conducted at a depth of 15 m near Seosaeng, Ulsan, Korea for 295 days (23 July, 2012 to 13 May, 2013). A total of 155 sea cucumbers were used and fed a mixed diet containing mud, mineral, wheat, fish meal, etc (3% of their body weight). At the end of the experiments, sea cucumber showed a higher survival rate in feed shelter (77.14%) rather than no feed shelter (64.71%). The specific growth rate (SGR) of sea cucumbers in feed condition (0.04% $day^{-1}$) was higher than that of no feed culture animals (-0.49% $day^{-1}$) during total experimental periods. The result was able to find a no significance difference in survival rate but a significance difference in SGR under feed and no feed treatments.

This study was conducted to evaluate the performance of the octopus pot according to mesh sizes. Entering behavior of Octopus minor and bait (Macrophthalmus japonicus) escape rate on the mesh sizes of the pots were investigated for six times in indoor tank. The sea trials for evaluating the performance of Octopus minor pot to different mesh sizes (22, 20 and 18 mm) were conducted for six times from 2017 to 2018 in the coastal sea of Deukyang Bay, the Republic of Korea. Behavior patterns of contact pot to leaved pot were more frequent than contact pot to bait search. When the octopus contacted to the pot, there was no clear search behavior to distinguish the mesh sizes. Total catch of 46% was accounted for 18 mm pots, followed by 34% at 20 mm and 20% at 22 mm (P < 0.05). Catch per unit effort was calculated as 30 g/pot at 22 mm, 44 g/pot at 20 mm and 59 g/pot at 18 mm. As a result of evaluating 50% selection of mantle length and weight on the mesh sizes, mantle length (mm) and weight (g) were 84.6 and 147.8 in 22 mm, followed by 20 and 18 mm.

The purpose of this study was to manufacture a wrist brace using a computerized tomography system, clinical design software (MediACE 3D Program), and 3D printer. After acquiring the Dicom file of the upper limb with a computed tomography, the wrist brace was designed using the MediACE 3D Program to create a "stereolithography" file. The designed wrist brace was printed using a 3D printer. To verify the effectiveness of wrist assistive device manufactured by 3D printing technology, the stress distribution of the pressure and orthosis applied to bone and skin is represented by finite element analysis. It is expected that the wrist brace can be manufactured by reinforcing the part where the damage caused by pressure and breakage of the brace frequently occurs with the result of finite element analysis when producing the wrist brace.
