The informal economy is a large part of the urban economy. The informal economy accounts for about half of Pakistan's GDP. This research examined nine different areas of Rawalpindi's Central Business District's business sector (CBD). A survey of 404 respondents from 16 CBD marketplaces enables a comprehensive examination of who works in the informal and formal economic sectors, how much they earn, their goals, perception of their job, and their degree of similarity to the rest of the working population. Furthermore, the statistics illustrate the pro-cyclical connections between the informal economic sector and the formal economy. The Multinomial Logistic Regression (MLR) technique is used for the analysis. The MLR results indicated the informal economic sector holds positive relation with earning members in a family, business expertise, average business sale, and negative relation with education level, satisfaction with government tax policies, household expense, and average investment in the business. From a resilience standpoint, governance is considered an intentional collective action to preserve a stable system condition. Hence, the current study recommends tax reforms and government institution reorganization to mobilize the informal sector and make effective institutional governance.

Emperor Minh Mang (明命), the second ruler of the Nguyen Dynasty in Vietnam, reigned from 1820 to 1841. He is widely regarded by contemporary historians as the most distinguished monarch of his dynasty, despite some controversial policies. One aspect of his extraordinary legacy is the remarkable 142 offspring he sired - 78 princes and 64 princesses - earning him the unprecedented distinction of having the most progeny among kings in world history. Vietnamese people suppose Minh Mang's prolific reproductive success to the consumption of a specially prescribed medicine known as Minh Mang Thang (明命湯, MMT). This medicine, often associated with sexual potency and fertility, is characterized by intriguing names such as "One night Five sexes," "One night Six sexes born Five babies," or "Six sexes Three pregnancies." Vietnamese folklore vividly recounts Minh Mang's exceptional sexual prowess, attributing it to the use of MMT. MMT formulations, which include various herbs, notably Korean ginseng, may incorporate additional botanical ingredients depending on their intended purpose. This paper aims to explore the origins, history, ingredients, and applications of MMT, unraveling the mystery behind this mystical prescription that has inspired several oriental medicinal researchers. Through this investigation, we seek to shed light on the cultural and historical contexts surrounding Minh Mang's use of MMT and its enduring impact on traditional Vietnamese medicine and folklore.

This paper analyses the performance of push-pull strategy by Multicharts' portpolio tool. This strategy decreases a risk of option sell by moving an exercise price to outward and compensates the profit by doubling contracts. This strategy also makes risk-free option sell to move inward for earning gain. This strategy basically uses several symbols. And this feature makes impossible to use a portpolio tool. However, This paper provides the method to use it with extracting intrinsic data from a symbolname. As an experiment for one month of september experiment options, it shows 1.5 million won in case of 5-displace and also shows 32 million won in case of 2.5-displace. If a Margin is enough, this strategy always earns profit, but it's difficult to be applicated in real trades because of a margin risk.

The purpose of this study was to investigate the relationship between household income, consumption wants for education, private education expenses, and old-age economic preparation behaviors in mothers with school-aged children. The participants in this study comprised 393 mothers living with children aged 8.19 in Daegu. All participants had wage-earning husbands. A questionnaire was used to collect the data. Factor analysis was conducted using SPSS and structural regression analysis was performed using AMOS. The main results of this study were as follows: The participants' old-age economic preparation behaviors were influenced by their household income, the proportion of private education expenditures they paid, and the perceived burden the participants had of these private education expenditures. The consumption wants for education in mothers with school-aged children had no significant impact on the proportion of private education expenditures paid by the participants. Household income, proportion of private education expenditures, and perceived burden of the private education expenditures had a direct effect on the old-age economic preparation behaviors of the participants. When the perceived burden of the private education expenditures was mediated, the consumption wants for education in mothers with school-aged children had an indirect effect on their old-age economic preparation behaviors.

This study aims to investigate the patterns and causes of the marital duration. Data used for this study are ten waves of Korean Labor and Income Panel Study(KLIPS) in 1998~2007, in which the final sample consists of 2,397 households. The Life-table method is used for describing the overall patterns of marital duration by birth-cohorts and different education groups, and the Cox proportional hazard regression model is used to identify significant factors on the marital duration. The results show that among the all respondents, the 0.79% has divorced or separated within five years after marriage, 2.12% within 10 years, and 5.84% within 20 years, respectively. In addition, the Cox regression results show that the marital duration is significantly affected by the birth-cohorts of respondents and their spouses, education level, earning of spouses, co-residence with parents, and household income. This implies that the hazard rate of marital disruption is higher for younger cohorts, individuals with lower education and economic status, persons living with parents-in-law, compared to their counterparts. Thus, it is necessary to implement social welfare policies applicable for these persons.

The aim of this study is to investigate and develop the extended models for Economic Cash Amount(ECA), Cash Break Even-Point(BEP), and Cash Flow Statement(CFS) by referencing systematic literature review in the field. The study develops three extended models to determine the optimal cash amount: ECA model with interest opportunity cost, financing transaction cost and financing fail cost, ECA model with daily cash supply and interest opportunity cost, ECA model with financing fail cost and interest opportunity cost. Earnings Before Interests, Tax, Depreciation and Amortization(EBITDA) is obtained by subtracting noncash depreciation costs from Earning Before Interest and Tax(EBIT), which is efficient metric to evaluate operating cash flow. The research also develops two extended Cash BEP models, considered as interest and corporate tax, in order to indentify the break-even point as EBITDA equals zero. Furthermore, this paper proposes the modified version of CFS by introducing the reclassification of operating and financing accounts in the statement of financial position. In addition, the study also present the reclassification of five types of profit, such as gross profit, EBIT, ordinary profit, special profit, and net profit within the statement of comprehensive income. In order to provide a better understanding of the proposed cash flow models, numerical examples, such as two-sample t test and Analysis of Variance(ANOVA), are presented to demonstrate the statistical significance according to the industrial types for net working capital(i.e cash-to-cash), net profit, operating cash flow and free cash flow.

Objectives : This study aimed to analyze the trend of financial balance of Korean medicine clinics during 20 years, and to provide basic information for adjusting the fee schedule of Korean medicine procedures in national health insurance(NHI). Methods : We collected 6 financial analysis reports for Korean medicine clinics from the Association of Korean Oriental Medicine(AKOM). The data on incomes, costs and EBIT(earning before interests and taxes) of subject clinics were abstracted, and their long-term trends were evaluated. Results : The proportion of insurance income in total income increased from 23% to 56% during 20 years. Among 5 treatment groups, 'non-insurance medication' took up 65~67% of total incomes in 1997, but its proportion decreased to 42.4% in 2007. 'medical procedure, physical therapy and others' increased from 12.4% in 1987 to 29.2% in 2007. The labor cost was major part of total cost and its proportion maintained from 52% to 54%. Cost of 'non-insurance medication' was on the decline from 41% in 1996 to 31.6% in 2007. EBIT were -17.4 million won in 1996, and 18.4 million won in 2007. Conclusions : Financial balance of Korean medicine clinics improved until early 2000, but it became worse in 2007. Though deficits from NHI procedures has been covered up by profit from 'non-insurance medication', health insurance became a major source of income during last two decades.

Objectives : Korean director Bong Joon-ho's movie 'Mother' is a story about a woman who struggles to save her son from an indictment of murder. This movie premiered at the 2009 Cannes film festival. The present study aimed to investigate the various roles of acupuncture in the plot from the perspective of movie professionals, including critics, writers and producers. Methods : We investigated the meaning of acupuncture as a subject matter in this movie. Participants who work in the film industry or are studying film were included. Survey questions were organized in a two part open-ended questionnaire and in multiple-choice form. The questionnaires were distributed via e-mail or the subjects were contacted directly. Results: In this movie, acupuncture serves at least three roles. The first role it serves is as a symbol of the mother role in her son's life and in her community. Acupuncture also works as a conduit for communication and a means of earning a living for the mother. She strives to clear her son's name by discovering the real murderer through performing acupuncture. Finally, the acupuncture box is crucial in the son's understanding of the mother's role in the crime. Seventy-nine percent of those surveyed responded that acupuncture was an important motif in this movie. Conclusions : These findings, in addition to those of previous studies, suggest that acupuncture can serve as a useful context for mass communication in media. The understanding of the meaning of acupuncture in the movie provides useful information on the perception of acupuncture modality today.
