To object of this study was to analyze the effects of air pollution of industrial park to the environmental-ecology characterization in the Sa-Sang Park and the vicinity of South Gate in Mt. Geumjung. 6 transects(each size 400m2 were set up and surveyed each park. The relationships of the distribution of dominant groups for forest vegetation structure and the environmental condition between the Sa-Sang Park and the vicinity of South Gate San-Sung Amusement Park were analyzed by similarity index, frequencies of tree species, importance value, soil pH, SO2ㆍCOㆍNO2 and PM10 density of air and tree vitality. The results obtained were as follows, 1. For analysis of vegetation structure in the Sa-Sang Park, upperstory of forests was mostly consisted of Pinus thunbergii Parl and partly of Alnus japonica Steudel. In midstory, major components were Alnus japonica Steudel and partly of Pinus thunbergii Parl. In lower story Rhus sylvestris S. et Z, which was known to be resistant to air pollution, was found in large number. While the vicinity of South Gate in Mt. Geumjung has various species and stable forest vegetation, upperstory of forests was mostly consisted of Pinus rigida Mill and partly of Pinus densiflora S. et Z. Quercus serrata Thunb. Quercus mogolicα Fischer. Alnus hirsuta Rupr. In midstory, major components were Pinus rigida Mill and Alnus hirsuta Rupr. In lower story Rhododendron yedoense Maximowicz var. poukhanense(Le'v.) Nakai. and Rubus crataegifolius Bunge, Lespedeza bicolor Turcz. Similarity index in the Sa-Sang Park and the vicinity of South Gate in Mt. Geumjung was 42.31%. 2. Frequencies class of tree species were analyzed A(23.53%), B(17.65%),C(11.76%), D(5.88%), E(41.18%) in the Sa-Sang Park and A(29.41%), B(29.41%). C(23.53%), DC5.88%), E(11.77%) the vicinity of South Gate in Mt. Geumjung 3. Soil pH decreased to below pH 0.7 in the Sa~Sang Park as compared to pH 4.9in the vicinity of South Gate in Mt. Geumjung. In addition Water content decreased to below 7.7% in Sa~Sang Park as compared to 9.3% the vicilli앙 of South Gate in Mt. Geumjung. While SO2ㆍCO2 density of air and tree vitality were higher than those in the vicinity of South Gate in Mt. Geumjung. It is concluded that the Sa~Sang Park is only afraided to survive stronge tree species which resist to air pollution and decrease a function of city park in a few years that tree vitality of the Sa~Sang Park is higher than those in the vicinity of the South Gate in Mt. Geumjung. as a result environmental factorsCfor example SO2ㆍCOㆍNO2 and PM10 density of air, Water content, Soil pH and so on).

박용래 시의 전원의 의미와 물의 상상력

박형준(Park, Hyung-Jun) 한국현대문학회 2013 한국현대문학연구 Vol.0 No.40

박용래는 문명에 의해 사라져가는 풍경들에 주목하면서 그것들이 가지고 있는 갸륵하고 어여쁘고 소박한 측면을 향토적인 언어로 그려내었다. 그러나 그러한 자연현상보다 더 중요한 것은 그것들 속에 숨겨진 기억 속에서만 존재하는 사물들이다. 한 작가가 그리는 풍경은 실제적 지리가 아니고, ‘내면적 지리’ 혹은 ‘주관적 지리’라고 할 수 있다. 그렇기 때문에 박용래의 시에 나타나는 고향의 풍경은 단순히 자연 속에 놓여 있는 것이 아니라, 과거와 현재가 섞여 있고, 영혼과 사물이 혼재한 그러한 자연속이다. 이러한 박용래의 시에서 ‘물’은 무엇보다 그의 ‘전원으로의 귀소(歸巢)의 설계’를 매개하는 뚜렷한 이미지이다. 물이라는 심상은 그 안에서 우리가 우리 자신을 직접 ‘체함’하는 것이기 때문이다. 물의 이미지는 먼저 ‘접분(接分)의 상상력’으로 나타난다. 이것은 사물과 인간을 자기의 욕망으로만 끌어들이지 않고 표면과 이면의 경계에 자신을 위치시킴으로써 자신의 근원적인 고독의 발원지인 과거와 그 흔적이 사라져가고 있는 현재를 잇고자 함이다. 박용래는 자신의 감정을 철저하게 배제한 채 그것들을 응시함으로써 가물가물 사라지고 있는 지나간 시간과 그것들이 존재하지 않는 현실의 시간을 짜맞추어나간다. 또한 그의 시에서 나타나는 극소량의 물의 이미지인 이슬, 눈물, 샘물 등은 정화(淨化)의 심리학에 해당되는 것으로서 외적 경험에 속해 있는 것과는 다른 양상을 보인다. 우리는 박용래의 이러한 역동적인 물 이미지에서 정화를 통해 풍부하고 혁신적인 다가치(多價値)의 힘을 발견할 수가 있다. 그리고 그 역동적인 물은 그 신선한 실체의 반영으로 우리를 인도하며 우리 자신을 생명의 에너지로 충만하게 한다. 본고는 이와 같이 박용래의 시에 나타난 전원의 의미와 물의 이미지를 통해 허물어진 세계를 상상력으로 일으켜 세우고자 하는 의지적인 “전원으로의 귀소(歸巢)의 설계”를 파악하고자 하였다. Yongrae Park focused on landscapes that have been disappeared by civilization and wrote the praiseworthy, beauty, and rustic aspect of the landscapes through rural words. However, more important thing than these kinds of natural phenomena is something being inside of the memories hid in the natural phenomena. The landscape, which a writer expresses, can be said ‘inner geography’ or ‘personal geography,’ not an actual geography. Therefore, the landscape of a hometown that the Yongrae Park’s poetry shows is not existing in a nature. It is existing in another nature that the past and present are mixed and souls and things are mixed in a complex. In Yongrae Park’s poem, ‘Water’ is the distinguished image carrying his ‘the homing design as a pastoral. It is because that the image of water is, inside of it, that we directly ‘experience’ ourselves. First of all, the image of water comes up as ‘the imagination of the Meeting and Dividing of Objects.’ This does not rope things and humans in only one’s desire, but it is to forget the past, which is one’s source of underlying loneliness, and the present, which its trace is disappearing, through locating oneself on the boundary of the surface and the other side. Yongrae Park interknits the passed time, dimly disappearing, and the present time that the passed time does not exist anymore by staring at the passed time without his emotions thoroughly. Also, dew, tear, and spring water, which were shown in his poetry as a thimbleful of water, are included in the purification of psychology, and these show different phase from the things belonged in external experiences. We can find out the plentiful and innovational power of lots of values through the dynamic water image. Furthermore, the dynamic water image leads us to the reflection of the fresh noumenon, and the image makes us plentiful of the energy of a life. This treatise, like above, tried to understand that volitional “the homing design as a pastoral” to set up the world destroyed by imagination, through the meaning of pastoral and the image of water that were shown in Yongrae Park’s poem.

人體相應構造에 依한 建築管理Ⅱ : -Hand Reflexolgy에 關하여-

朴亨夏 釜山水産大學校 1990 論文集 Vol.44 No.-

The result of comparative group strudies on the nature and characteristics of Hand Reflexology using acupuncture as a health treatment to cure the diseases and aches in our body by stimulating a specific part or point of the body are as follows; 1) We can keep in good health by stimulating a specific part of our body. 2) Many nerve cells are concentrated in the hand, and it is possible to cure illness using them. 3) We can guess our state of health from the state of development, and the structure, of our hands. 4) The hand performs the most complex and diverse skills of our body because of its function and struture. 5) Yu Tae-woo's finger theory puts forward hand acupuncture treatment according to a contracted corresponding system of the human body in which the tip joint of the middle finger corresponds to our head. 6) Park Jae-woo's finger theory forms a similar contracted corresponding system of body but in which the tip joint of the thumb corresponds to our head. 7) As Yu's finger theory takes shape with two arms and legs lifted up and Park's finger theory follows a pattern with them put down, their corresponding systems assume confilcting representations which differ in their positioning of the representative parts of the body in the hand by 180˚. 8) Park's and Yu's theories of the blood vessels in the finger conflict regarding the positions and theories of the blood stream 9) Yu's and Park's refexologies agree that there exists a passage of energy which are linked to the blood vessels of body in a direct relationship to the contracted corresponding system embodied in the hands. 10) Sung-hun's reflexology assumes the contracted corresponding structure of the body in the hand to correspond to that of Yu's. 11) Sung-hun's reflexology is a healing method that cures the disease by letting blood from a part of the hand corresponding to our viscera and entrails by considering the hand as a microcosm of the whole body. 12) By Sung-hun's reflexology, the tip joints of index and ring fingers correspond to the hand itself and all functions of the body can be adjusted using the theory. 13) Sung-hun's reflexology is a theory by which we can perceive our health for the future and our family's health using the hand to represent the body, and by which, at the same time, we can improve health indirectly. 14) Do-in theory is a healing method based on the skin conditions of the hand. 15) According to the finger interpretation, our thumb corresponds to our brain, but this throry does not follow the contracted body structure using the hand. 16) Do-in theory is that the thumb can control the function of the brain, the index finger the stomach, the middle one the circulatory organ system, the ring finger the nervous system, and the little finger the respiratory organs and the genital organs, and it shows the same tendency as Takenouchi theory from the fact that a lower part of the little finger corresponds to the genital organ. 17) Takenouchi theory is a healing method that oures a physical disease using diagnosis of the change of skin color of the palm and back of the hand. 18) Takenouchi theory does not follow the contracted corresponding body structure, but relies on corresponding responses from parts of the body by clinical tests using acupuncture appied to the hand. 19) Maybelle Segal's reflexology is very similar to that of Kevin & Kunz's in that acupuncture to specific points of our fingers stimulate responses corresponding to the sinus of the brain, but Segal's theory is different from the latter in that a lower part of the wrist also is said to stimulate responses corresponding to each organ of body. 20) Kevin and Kunz's reflexology is a corresponding response system based on the Vertical zone theory that ten distinct polarity flows come from the tips of each of the fingers and toes. This theory puts stress on the flow of energy in the Vertical zone. 21) Bowling Pin's reflexology is another interpretation of the contracted corresponding system of the hand laying stress on the torso. 22) Yu's, Park's and Sung-hun's reflexologies are theories that the contracted body form exists in the hand, but Maybelle's and Kevin and Kunz's reflexologies have the structure of the body divided into the right and left and sides by the central Vertical axis of body corresponding to the right and left hands respectively.

Comparison of the Crystallization Behavior of Silica Between Mg and Al‑Phosphate Used in Tension Coatings of Grain‑Oriented Electrical Steel

Hyung‑Ki Park,Min‑Soo Han,Chang‑Hwan Chang,Jong‑Tae Park,박창수,Hyung‑Don Joo 대한금속·재료학회 2020 METALS AND MATERIALS International Vol.26 No.3

The effect of the phosphate component on the thermal stability of tension coatings was investigated with a focus on thecrystallization behavior of amorphous silica in the tension coating. After stress-relief annealing, core loss of samples coatedwith a Mg-phosphate was improved, while that coated with an Al-phosphate was deteriorated. The domain wall spacing ofthe samples coated with Mg- and Al-phosphates was respectively increased and decreased after stress relief annealing. Thismeans that the stress relief annealing did not much diminish the tensile stress for Mg-phosphate coating but much diminishedthe tensile stress for Al-phosphate coating. Based on FTIR and XRD results, we found that the crystallization temperatureof silica with Al-phosphate was lower than that of silica with Mg-phosphate. The crystallization of silica was accompaniedby an abrupt volume change, which formed cracks in the tension coating and deteriorated the tensile stress.

Goryeo hand-reflexology and hand-foot-reflexology therapies .consider a part or whole part of body as face, hand, foot, ear and eye according, to either which part of body would be similar to which part of body or which function is projected to which part of body. Among the various methods of therapies, hand-reflexology therapies of You`s and Pack`s styles are widely used. Since these two styles are opposite exactly to each other; it is Park`s theory that develops methodologies which are exactly apposite to those of You`s they. Based on these two therapies, strong stimulation of heart was carried put through You`s arid Pak`s methods and changes of body temperatures and pulses were investigated by measuring the body temperatures, pulses, and pressures before and 30 minutes after needle insertion. The major results are as follows: 1) By carrying out the strong, stimulation of ,heart through You`s method, it was found that body temperatures, pulses, and blood pressures wire all increased after needle insertion compared with those of before needle insertion. However, statistical significance was observed only in the case of body temperature(p$lt; .05). 2) By carrying out the strong stimulation of heart through Park`s method, it was found that body temperature, pulses, and blood pressure all decreased after needle insertion compared with those of before needle insertion, However, statistical significance was observed only in the case of body temperature(p$lt; .05). 3) Based on the results obtained in this works, it was turned out that You`s and Park`s styles were opposite even in clinical experiments such as body temperature, pulses, and blood pressure as was case in the theoretical view points.

Jae‑Young Park,Kwangsuk Park,Bosung Seo,Julien O. Fadonougbo,Tae‑Wook Na,Ki Beom Park,Hyeon‑Tae Im,Nong‑Moon Hwang,Hyung‑Ki Park 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.7

This study examines the insulation coating technology of Fe–Si–Cr powder via selective oxidation annealing, which oxidizeselements selectively by controlling the oxidation potential. The study calculated the oxidation driving force of Fe, Si, andCr, and conducted a thermodynamic analysis of oxidation and reduction conditions according to temperature and oxidationpotential. Based on the results, a selective oxidation annealing was performed in an atmosphere in which Fe is reduced andonly Si and Cr are selectively oxidized. The oxidation potential was controlled through the partial pressure ratio of hydrogenand water vapor. The XPS analysis results confirmed that a Si and Cr complex oxide layer formed on the powder surfaceafter the selective oxidation annealing. Afterward, withstanding voltages were analyzed to evaluate the insulation property. Then, the withstanding voltage of the powder applying the selective oxidation annealing increased significantly comparedto that of the initial powder. Further analysis showed that the powder annealed in an air atmosphere had a significantly lowersaturation magnetic flux density than the initial powder, while the powder applying the selective oxidation annealing hadonly a slightly reduced saturation magnetic flux density.

This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

C-reactive protein accelerates DRP1-mediated mitochondrial fission by modulating ERK1/2-YAP signaling in cardiomyocytes

( Suyeon Jin ),( Chan Joo Lee ),( Gibbeum Lim ),( Sungha Park ),( Sang-hak Lee ),( Ji Hyung Chung ),( Jaewon Oh ),( Seok-min Kang ) 생화학분자생물학회 2023 BMB Reports Vol.56 No.12

C-reactive protein (CRP) is an inflammatory marker and risk factor for atherosclerosis and cardiovascular diseases. However, the mechanism through which CRP induces myocardial damage remains unclear. This study aimed to determine how CRP damages cardiomyocytes via the change of mitochondrial dynamics and whether survivin, an anti-apoptotic protein, exerts a cardioprotective effect in this process. We treated H9c2 cardiomyocytes with CRP and found increased intracellular ROS production and shortened mitochondrial length. CRP treatment phosphorylated ERK1/2 and promoted increased expression, phosphorylation, and translocation of DRP1, a mitochondrial fission-related protein, from the cytoplasm to the mitochondria. The expression of mitophagy proteins PINK1 and PARK2 was also increased by CRP. YAP, a transcriptional regulator of PINK1 and PARK2, was also increased by CRP. Knockdown of YAP prevented CRP-induced increases in DRP1, PINK1, and PARK2. Furthermore, CRP-induced changes in the expression of DRP1 and increases in YAP, PINK1, and PARK2 were inhibited by ERK1/2 inhibition, suggesting that ERK1/2 signaling is involved in CRP-induced mitochondrial fission. We treated H9c2 cardiomyocytes with a recombinant TAT-survivin protein before CRP treatment, which reduced CRP-induced ROS accumulation and reduced mitochondrial fission. CRP-induced activation of ERK1/2 and increases in the expression and activity of YAP and its downstream mitochondrial proteins were inhibited by TAT-survivin. This study shows that mitochondrial fission occurs during CRPinduced cardiomyocyte damage and that the ERK1/2-YAP axis is involved in this process, and identifies that survivin alters these mechanisms to prevent CRP-induced mitochondrial damage.
