This urban centralization is expected to develop rapidly, with 75% of the population living in the city by 2035. Large cities are becoming unsustainable due to side effects such as environmental pollution, severe traffic jams, excessive energy depletion, and destruction of the natural ecosystem. In addition, the happiness index of citizens of large cities is also falling because of high crime rates and safety accidents, the work-life imbalance caused by inequality and polarization, and overly competitive education. To solve this problem, Smart City, an IT-based future city model, was born. The Korean government is also actively attempting to improve urban competitiveness and promote sustainable development through efficient construction and operation of smart cities as a national focus project. To support the effort, we review the basic directions and strategies of Sejong City's Smart City service infrastructure based on the comprehensive national land plan, Smart City plan, and Smart City strategy plan.

Wind energy can be utilized for the generation of electricity, due to significant wind potential at different parts of the world, some countries have already been generating of electricity through wind. Pakistan is still well behind and has not yet made any appreciable effort for the same. The objective of this work was to add some new strategies to calculate Weibull parameters and assess wind energy potential. A new approach calculates Weibull parameters; we also developed an alternate formula to calculate shape parameters instead of the gamma function. We obtained k (shape parameter) and c (scale parameter) for two-parameter Weibull distribution using five statistical methods for five different cities in Pakistan. Maximum likelihood method, Modified Maximum likelihood Method, Method of Moment, Energy Pattern Method, Empirical Method, and have been to calculate and differentiate the values of (shape parameter) k and (scale parameter) c. The performance of these five methods is estimated using the Goodness-of-Fit Test, including root mean square error, mean absolute bias error, mean absolute percentage error, and chi-square error. The daily 10-minute average values of wind speed data (obtained from energydata.info) of different cities of Pakistan for the year 2016 are used to estimate the Weibull parameters. The study finds that Hyderabad city has the largest wind potential than Karachi, Quetta, Lahore, and Peshawar. Hyderabad and Karachi are two possible sites where wind turbines can produce reasonable electricity.

Purpose: Postoperative exercise for acute Achilles tendon rupture is important for a patient's return to daily life and sports. On the other hand, the protocol requires considerable effort to educate patients and continuous checking. This study evaluated the outcome of a new simple and delayed rehabilitation protocol after Achilles tendon rupture repair. Materials and Methods: From July 2014 to November 2020, one hundred eighty-three patients were operated on by one surgeon. The exercise protocol was classified into two methods. One group (immediate protocol, control group) started immediate full weight bearing with a 20° plantar flexion range of motion from two days postoperatively. Ankle dorsiflexion was restricted to 0°. The other group (delayed protocol, case group) started full weight bearing with a controlled ankle motion boot from two weeks postoperatively. No range of motion exercise was allowed until six weeks postoperatively. Age, sex, body mass index, ankle range of motion, muscle power, time to return to previous physical activity, functional score, and complication rate were evaluated. The results of the two groups were compared using a Mann-Whitney test. Statistical significance was set as p<0.05. Results: The range of motion, double heel rising, and one-leg standing were achieved faster in the control group (p<0.05). However, single-heel rising, repeated single-heel rising, return to previous activity (work, run, and sport), and functional scores showed no statistical difference (p>0.05). Conclusion: Simple and delayed postoperative rehabilitation of acute Achilles tendon rupture without active range of motion exercises showed satisfactory functional results and a low complication rate.

The objective of this paper is to analyze the disparities in perceptions regarding gender-related matters among students at K University, determined by their gender, and to propose solutions within the university education system. The results of the study are as follows. First, many men believe that there is no structural discrimination against women and that men are discriminated against, whereas women show the opposite. Second, men and women show statistically significant differences in perception of women's level of effort, reasons for low income, and work ability after employment. Third, men show unfavorable attitudes towards feminism compared to women. Fourth, the reasons men show hostile attitudes toward the female quota system and feminism include the influence of the traditional gender role model imposed on men and the difference in men's and women's views on structural inequality. To reduce the perception gap between men and women, it is necessary to reconsider hegemonic masculinity, apply issue-centered education using accurate information, publicize issues by preparing a mistake-friendly space, and respond to the perception gap at the university level from the perspective of citizenship education.

As the demand for p-type semiconductors increases, much effort is being put into developing new p-type materials. This demand has led to the development of novel new p-type semiconductors that go beyond existing p-type semiconductors. Copper iodide (CuI) has recently received much attention due to its wide band gap, excellent optical and electrical properties, and low temperature synthesis. However, there are limits to its use as a semiconductor material for thin film transistor devices due to the uncontrolled generation of copper vacancies and excessive hole doping. In this work, p-type CuI semiconductors were fabricated using the chemical vapor deposition (CVD) process for thin-film transistor (TFT) applications. The vacuum process has advantages over conventional solution processes, including conformal coating, large area uniformity, easy thickness control and so on. CuI thin films were fabricated at various deposition temperatures from 150 to 250 ℃ The surface roughness root mean square (RMS) value, which is related to carrier transport, decreases with increasing deposition temperature. Hall effect measurements showed that all fabricated CuI films had p-type behavior and that the Hall mobility decreased with increasing deposition temperature. The CuI TFTs showed no clear on/off because of the high concentration of carriers. By adopting a Zn capping layer, carrier concentrations decreased, leading to clear on and off behavior. Finally, stability tests of the PBS and NBS showed a threshold voltage shift within ±1 V.

The Ministry of Employment and Labor announced a roadmap for reducing serious accidents to create a "safe and healthy workplace, happy Korea" and ordered a risk assessment for all work processes in all workplaces on November 30, 2022. Accordingly, even workplaces that handle new chemicals must conduct risk assessment when introducing new chemicals, but the risk assessment techniques currently proposed by the government focus on preventing conventional accidents such as falls, getting caught, and bumping. Currently, there is a Chemical Hazard Risk Management (CHARM) technique that is most commonly used for chemical risk assessment, but in small and medium-sized businesses that lack professional manpower related to chemical substances, there are many technical terms in the technique and it is difficult to interpret, so its utilization is very low. Therefore, the purpose of this study is to present a method that can make risk assessment easier and simpler before handling new chemicals so that it can be used well in small and medium-sized businesses that lack professional manpower related to chemical substances. Through actual cases, the method of using CHARM was confirmed step by step, and based on this, risk reduction establishment and execution methods were derived. Based on the results of this study, it is expected that it will be used as the best tool for preventing accidents such as acute poisoning when handling chemicals in small and medium-sized workplaces that lack professional manpower related to chemical substances and make every effort to protect workers' health.

Focusing on Hwaseokjeong in Paju, the work seeks to clarify the social production of Nujeong (樓亭: Korean traditional pavilions) space, which took place over the 1960s and 70s, and its cultural-political implications. To make the effort as such meaningful, a theoretical framework based not merely on the thesis of 'social production of space' advocated by Henri Lefebvre but especially on some discussions related to 'state production of space' is prepared, according to which Hwaseokjeong is analyzed and explained. As a consequence, two principal arguments are put forward: one is that Hwaseokjeong was a social space which had been built and constructed in accordance with the unique mode of production dominating Korean society at that time called 'the state mode of production (le mode de production étatique)'; the other is that what lies beneath the denotation of a 'social space of tradition restoration' that Hwaseokjeong appears to carry is in fact the connotation of 'infiltration of anti-communist ideology'. All of these claims are once again supported both by examining Roland Barthes's semiology and mythologies and by considering Hwaseokjeong's P yeonaek (扁額: a plaque or framed text) as 'the practice of naming power through Jesa (題詞: inscribing dedications)'. While providing a succinct summary, the paper finally evaluates what 'social production of space' implies to social practices of architecture and related criticisms by taking into account the relationship between visibility and readability of space including buildings.

This study focuses on developing a building object recognition technology for efficient use in the remodeling of buildings constructed without drawings. In the era of the 4th industrial revolution, smart technologies are being developed. This research contributes to the architectural field by introducing a deep learning-based method for automatic object classification and recognition, utilizing point cloud data. We use a TD3D network with voxels, optimizing its performance through adjustments in voxel size and number of blocks. This technology enables the classification of building objects such as walls, floors, and roofs from 3D scanning data, labeling them in polygonal forms to minimize boundary ambiguities. However, challenges in object boundary classifications were observed. The model facilitates the automatic classification of non-building objects, thereby reducing manual effort in data matching processes. It also distinguishes between elements to be demolished or retained during remodeling. The study minimized data set loss space by labeling using the extremities of the x, y, and z coordinates. The research aims to enhance the efficiency of building object classification and improve the quality of architectural plans by reducing manpower and time during remodeling. The study aligns with its goal of developing an efficient classification technology. Future work can extend to creating classified objects using parametric tools with polygon-labeled datasets, offering meaningful numerical analysis for remodeling processes. Continued research in this direction is anticipated to significantly advance the efficiency of building remodeling techniques.

The purpose of this study was to examine the learning competencies of students at a college from September 1 to November 30, 2017, in an effort to provide some information on how to foster learning competencies in college years, which lay the foundation for work and social lives. 1. The learning competencies of the subjects consisted of academic vision, student identity, cognitive regulation, emotional regulation, learning management and creating learning environments. Out of five points, they scored the highest in academic vision and student identity with 3.34, followed by learning management with 3.20, creating learning environments with 3.18, emotional regulation with 3.16 and cognitive regulation with 3.14. 2. There were statistically significant differences in academic vision according to age, the area of major, the academic credential of their fathers, commuting time, military service experience and career plans. 3. There were statistically significant differences in student identity and cognitive regulation according to gender, age, the area of major, the academic credential of their fathers, commuting time, military service experience and career plans. 4. There were statistically significant differences in emotional regulation according to age, the area of major, the academic credential of their fathers, commuting time, career plans and daily mean study hours. 5. There were statistically significant differences in learning management according to gender, age, the area of major, grade point average, the academic credential of their fathers, career plans and daily mean study hours. 6. There were statistically significant differences in creating learning environments according to gender, age, the area of major, the academic credential of fathers, commuting time, career plans and daily mean study hours. As they were poorest at the cognitive regulation area among the areas of learning competencies, self-directed learning programs that deal with how to study, learning process, how to take notes and arrange them, how to link different pieces of acquired knowledge and how to map out study plans should be developed to give support to students.
