This study examined the influence of ESG performance on the firm value of Chinese equipment manufacturing companies over the period from 2011 to 2020. The analysis indicated that while ESG performance exerted a negative influence on firm value, this impact was not statistically significant. These findings substantiate the Institutional Difference Hypothesis (IDH), which posits that country-specfic institutional variations sifnificantly shape the strategic decision-making of organizations. When disaggregating the three components of ESG, variations in the results were observed both for overall ESG performance and for each individual dimension. Of the three dimension elements, the environmental (E) and governance (G) facets had a negative bearing, whereas the social (S) facet had a positive influence. Notably, only the governance dimension (G) demonstrated a statistically significant influence. These outcomes affirm the institutional difference hypothesis, illustrating divergent results across distint ESG dimensions.

Compared to previous in-vitro test, FE model showed reliable motion patterns. A finite element model of a 50th percentile male neck was developed to study the mechanics of whiplash injury while the rear impacts. The model was consisted of the whole cervical vertebrae including part of occipital, intervertebral discs. which were modeled using linear viscoelastic materials and posterior elements. The sliding interfaces were defined to simulate contact phenomena in facet joints and in odontoid process. All ligaments and atlanto-occipital membrane were modeled as nonlinear bar elements. Only muscle elements were not considered. Motion of each cervical vertebra was obtained from the dynamic simulation with a MADYMO model for 15 km/h $40\%$ rear end offset impacts. Soft tissue neck injury(STNI) was investigated with a developed FE model. In FE model analysis, the high stress was appeared at C3/C4 disc in offset impact. Further research is still needed in order to improve the developed neck FE model for many different crash patterns.

We have analyzed the biomechanical characteristics of cervical spine after total disc replacement using finite element analysis. A finite element model of C2-C7 spinal motion segment was developed and validated by other experimental studies. Two types of artificial discs, semi-constraint and un-constraint, were inserted at C6-C7 segments. Inferior plane of C7 vertebra was fixed and 1Nm of moment were applied on superior plane of C2 vertebra with 50N of compressive load along follower load direction. Mobility of the cervical spine in which each artificial disc inserted was higher than that of intact one in all loading conditions. Also, high mobility at the surgical level after total disc replacement could lead higher facet joint force and ligaments axial stresses. The results of present study could be used to evaluate surgical option and validate the biomechanical characteristics of the implant in total disc replacement in cervical spine.

The purpose of this study to analyze the effect of Mindfulness on the Therapeutic Relationship using System Dynamics. The biggest factor in psychotherapy's treatment outcome is the Therapeutic Relationship including the quality of the therapist (empathy, therapeutic presence) and therapy alliance. Mindfulness practice can facilitate the therapeutic relationship. In order to analyze the therapeutic relationship, I measure FFMQ(Five Facet Mindfulness Questionnaire), Empathy, Therapeutic presence and Therapy alliance. Participants consist of 55 mental health professionals (doctor, psychologist, psychiatrist, counselor, social worker). The result of the study will be explained. First, with the causal loop diagram research, I analyze how mindfulness can influence the quality of therapist and therapy alliance. The result of literature research indicate that mindfulness increase therapist's empathy, congruence, therapeutic presence, flow, therapy alliance. And then mindfulness reinforces the ability of therapeutic relationship. Secondly, through the real data research and simulation analysis, mindfulness practicing period (year and hour a day) of therapist is studied. The result of the therapist experiencing mindfulness practice period is over 5 years and the daily hours of practice is 2 - 2.5 hours in order to enhance the therapeutic relationship. After reviewing the result of the research it is important to understand the practicing period and daily practice of mindfulness. With daily practice and time, the level of mindfulness will increase and influence positively the therapeutic relationship between therapist and client.

Objective : To describe the underlying causes, surgical results, and prognostic factors in thoracic stenosis causing myelopathy, retrospective analysis for 28 cases of thoracic stenosis with surgery was performed Materials & Method : Twenty-eight patients(male, 15 ; female, 13) who underwent decompressive surgery for thoracic stenosis between 1987 and 1997 were analyzed. The mean age was 49 and the mean follow-up was 30.6 months. Statistical analysis with $SPSS^{(R)}$ was performed. Chi-square test was used for the analysis of relationship between subjects and multivariate analysis with general linear model was used to find prognostic factors. Result : Degenerative spondylosis was the most common cause, and three cases were associated with systemic diseases. Decompressive laminectomy was done in 23 cases, anterior decompression in four cases, and combined decompression in one case. Ossification of ligamentum flavum was found in 18 cases, facet hypertrophy in 13, ossification of posterior longitudinal ligament in six, and ventral spur in four. Postoperatively, 16 patients improved functionally and 4 patients worsened. The group of which initial symptom duration was less than two years showed better result(p=0.003). The group with sufficient decompression and no additional proximal stenosis had better outcome(p=0.002, p=0.001). Conclusion : Chronic myelopathy caused by thoracic stenosis can be reversible with appropriate decompression.

$BCl_3-Cl_2$ 플라즈마에서 이온 강화 식각 시 source power에 따른GaAs(100)의 표면 형태 변화를 연구하였다. Floating potential에서는 이온 포격(bombardment)이 거의 없기 때문에, 화학적 반응에 의존한 순수한 습식 식각에 의해 나타나는 것과 같이 <110> 능선과 {111} facet으로 이루어진 표면이 관찰 되었다. 이러한 형태는 식각 시작후 1분 이내에 형성되기 시작하여 시간이 지남에 따라 커진다. 동일한 압력에서 source power를 변화시키면 식각된 표면이 다른 형태를 보인다. 100 W 정도의 낮은 source power에서는 결정학적 표면이 형성되지 않지만, 900 W 정도의 높은 source power에서는 결정학적 표면이 잘 형성된다. 이것은 건식 식각에 필수적인 여기된 반응성 물질의 양이 source power에 크게 좌우되기 때문이다. 높은 source power에서는 반응성 물질의 농도가 높아지고, 열역학적으로 가장 안정한 GaAs(100) 표면이 형성 된다. 반면에 반응성 물질이 부족할 경우에는 표면 형태는 sputtering에 의해 결정된다. Scaling theory에 기초한 표면의 통계적 분석 적용 시, 두개의 spatial exponent가 발견 되었다. 하나는 1 보다 작고 원자 수준의 표면형태 형성 기구에 의해 결정되고, 다른 하나는 1보다 크며 facet 형성 기구와 같이 큰 규모의 형태 형성 기구에 의한 결과로 생각된다.

The purpose of this study is to analyze the various processes and patterns to build or synthesize class numbers in the 800 class of the Dewey Decimal Classification, Edition 20(1989). The results of the analysis are as follows: 1. The 800(Literature and rhetoric) class in the DDC system is the main class added analytico-synthetic principle positively to an enumerative scheme. 2. The facets to be a n.0, pplied in literature are language literary form literary period ; kind, scope, or medium ; notation 08(collection) or 09(criticism) literary feature, subject, author, etc. 3. In the 800 class, there are the five tables of precedence for literary forms aspects ; specific kinds of persons ; literary, period in relation to the aspects for works treating more than one literary form subforms, aspects and literary periods in the works treating a specific literary form. 4. The basic number synthesis of literary works proceeds through the various facets in the following sequence, as far as necessary for the item : base no. + literary form + literary time or period + kind, scope, or medium + notation 08 or 09 + subform + additional notation from T3C and other tables. 5. In view of the multiplicity of facets, their synthesis formulas take the following order : (1) Works about the literature : base no.(schedule) + language(T6) or form(T3B) (2) Works by or about individual author : base no.(schedule) + form (T3A) + period(schedule) + subform(T3A) (3) Works by or about more than one author, not restricted by language facet : base no.(schedule) + period(T1) ; base no.(schedule) + kind, scope, medium(T3B), or feature(T3C), or person(T5). (4) Works by or about more than one author, restricted by language facet : base no.(schedule) + form (T3B) + period(schedule) + subform(T3B) + notation 08 or 09(T3B) ; base no.(schedule) + notation 08 or 09(T3B) + 9(T3C) + area notation(T2) : base no.(schedule) + form (T3B) + notation 008 or 009(T3B) : base no.(schedule) + form (T3B) + kind, scope, medium(T3B) + notation 08 or 09(T3B) + period(schedule). (5) Affiliated literatures for which period numbers are not us base no.(schedule) + form (T3A or T3B), or notation 08 or 09(T3B) : base no.(schedule) + kind, scope, medium(T3B), feature(T3C), or person(T5) 6. The problems in the number building of the 800 class are the complexity and difficulty of number synthesis, the intrinsic weakness of from distinction and the inconvenience of retrieval inherent in the form class. In order to solve these problems, therefore, the citation orders and methods of DDC should be improved and synthesis patterns simplified from the point of view of its applicability and its usefulness in the "literature class".
