Background: Forward head posture (FHP) is a postural alignment of the cervical vertebrae that leads to increased gravitational load on cervical segmental motions. The overhead arm lift test assesses the ability to actively dissociate and control low cervical flexion and move the shoulders through overhead flexion. Objects: The purpose of this study was to explore muscle activities in the upper trapezius (UT), serratus anterior (SA), sternocleidomastoid (SCM), and lower trapezius (LT) alongside changes in head position during the overhead arm lift test in individuals with FHP. Methods: Fifteen subjects with forward head posture and fifteen subjects with normal subjcects were enrolled in this study. The patients performed the overhead arm lift test, and muscle activities of the UT, SCM, SA, and LT were measured using surface electromyography and by evaluating changes in head position. Independent t-tests were used to detect significant differences between the two groups and Cohen's d was calculated to measure the size of the mean difference between the groups. Results: The FHP group demonstrated significantly increased muscle activity of the UT ($32.46{\pm}7.64$), SCM ($12.79{\pm}4.01$), and LT ($45.65{\pm}10.52$) and significantly decreased activity in the SA ($26.65{\pm}6.15$) than the normal group. The change in head position was significantly higher in the FHP group ($6.66{\pm}2.08$) than the normal group. Effect sizes for all parameters assessed were large between the two groups. Conclusion: The subjects with excessive FHP displayed were unable to fix their heads in position during the overhead arm lift test. The overhead arm lift test can thus be used in clinical settings to confirm control of the neck in these subjects.

Today's environment of enterprise is changing. They have to face customers' demands with the right product, the right service and supply them at the right time. And aIso cut down logistics and inventory cost and bring up the Profit as much as they can. This means the change of putting enterprise first in importance to putting customer first in importance. therefore to correspond to customer's demand, shorting lead time is becoming a essential condition. The answer to this changes of environment is supply chain management In this study, we use Goldratt's drum-buffer-rope scheduling in between manufacturer and supplier. And when shortage of inventory occur, search for the supply chain's CCR. Pressing CCR for more production, and supply Inventory from logistic center to guide for inventory buffing. using logistic warehouse between manufacturer and supplier, can execute function of buffer.

Objectives The purpose of this study is to understand the formation of Jogakdaehwang-tang(JD-T)'s patholoy and the compositional change of it in Sasang Constitutional Medicine(SCM). Methods The pathologic condition in which JD-T was used and the change of its composition was studied in SCM Results and Conclusions 1. Jogak and Daehwang in "Dongmuyoogo Haedong" were presented with Ungdam because of the common purpose flowing the energy of lung. Therapeutic method for exogenous Ungibyeong in "Dongyisusebowon sangchobongwon" was subdivided into Hangwul's treated by Ungdam, and the heat pattern featuring contagious cold and constipation, treated by Jogakhwanggeumdaehwang-tang(JHD-T). 2. JD-T in "Dongyisusebowon Gabogubon" was used for Yangdok and Onbyeong which are exogenous disease causing by heat. The composition of JD-T has been completed as it included Mahwang, Gilgyeong, and Seungma derived from prescriptions relevant with Yangdok. 3. JD-T in "Dongyisusebowon Sinchukbon(Sinchukbon)" was included in pathology of Ganyeol, and it substituted Galgeunhaegi-tang(GH-T) for Onbyeong, not for Yangdok, so Galgeun and Seungma became the main drug in JD-T. Galgeunseung-gitang(GS-T) was created for treating heat pattern owing to Daehwang, its main drug, and moreover Jogak's effect is too strong. Therefore, Mahwang, Hwanggeum and Gilgyeong was excluded from the composition of JD-T. 4. The origins of JD-T could be Yiseonggugo-hwan, Daesiho-tang, Jowiseungchung-tang, Heukno-hwan, and GH-T. The change of JD-T went for them throughout JHD-T to JD-T. JD-T in "Sinchukbon" consists of Galgeun and Daehwang which directly gets rid of severe heat from small intestine, and Jogak and Seungma which help to eliminate mild heat existing from small intestine throughout nose to flesh.

The sorption of UO$_{2}$$^{2+}$ onto goethite and kaolinite under various experimental conditions was successfully interpreted using surface complexation modeling (SCM). The SCM approach used in this work is the triple-layer model (TLM) in which weakly bonded ions are modeled as outer-sphere (ion-pair) complexes and strongly bonded ions as inner-sphere (surface coordination) complexes. The change of ionic strength did not affect the U(VI) sorption onto goethite, thus the formation of inner-sphere surface complexes, (FeO)$_2$UO$_2$ and (FeO)$_2$(UO$_2$)$_3$OH$_{5}$ was assumed to simulate the effects of ionic strength and goethite concentration. On the other hand, the U(VI) sorption onto kaolinite showed ionic strength dependence, thus the formation of AlO-UO$_{2}$$^{2+}$(outer-sphere complex) and SiO(UO$_2$)$_3$OH$_{5}$ (inner-sphere complex) was assumed to simulate the experimental data. In the presence of carbonates, the sorption of U(VI) onto kaolinite decreased in the weakly alkaline pH range. This was well simulated assuming the formation of a outer-sphere surface complex, A1OH$^{2+}$- (UO$_2$)$_2$CO$_3$OH$_3$. Since SCM approach uses thermodynamic data such as surface complexation constants, it is more predictive than empirical modeling approach in which conditional values such as partition coefficient are used. used.

In recent years, high hardness steel is used for most of the material in many areas including aircraft, nuclear power, space exploration and automotive parts. Low CBN tools are widely used in industrial field which can effectively process high hardness steel of HRC 45 or harder. The results of this study demonstrated, when high hardness steel, SCM440 is turned with Low CBN tools coated with TiN and TiAlN coatings respectively, that both the thrust force and cutting force tends to increase with more increase in cutting force than thrust force, as the feed rate increases at constant cutting speed. In addition, the size of the cutting force and thrust force does not change with the increased cutting speed at the same feed rate, but the tool life is reduced if the cutting speed is increased to shorten the machining time. Therefore, it is recommended to limit the cutting speed at 250 m/min maximum or less. Furthermore, comparing the cutting force of the three tools at the same cutting condition, Tin coating tool showed the smallest cutting force and Low CBN was the next, and the TiAlN coating tools showed the largest cutting force.
